Description

電池式電源裝置 Battery type power supply unit

本發明係關於一種電池式電源裝置。 The present invention relates to a battery type power supply device.

有一種外觀圓柱形狀且可視為乾電池之無線接收驅動裝置(專利文獻1)。於專利文獻1中揭示有如下構成，即，無線接收驅動裝置收納內置電池及無線接收驅動裝置接收基板部，且將該無線接收驅動裝置接收基板部之輸出端子連接於馬達之輸入端子。藉由將該無線接收驅動裝置設於電動式玩具車之電池盒，便可對玩具車賦予無線通信功能。使用者可使用對無線接收驅動裝置進行操作之裝置，移動玩具車。 There is a wireless receiving driving device which is cylindrical in appearance and can be regarded as a dry battery (Patent Document 1). Patent Document 1 discloses a configuration in which a wireless reception drive device accommodates a built-in battery and a wireless reception drive device to receive a substrate portion, and the output terminal of the wireless reception drive device reception substrate portion is connected to an input terminal of the motor. By providing the wireless receiving drive device in the battery case of the electric toy vehicle, the wireless communication function can be imparted to the toy car. The user can move the toy vehicle using a device that operates the wireless receiving drive.

於將無線接收驅動裝置安裝於玩具車之電池盒之狀態下，玩具車之馬達及外部開關係與無線接收驅動裝置串列連接。伴隨馬達等感應性負載之接通/斷開，而於馬達產生因逆起電力所致之較高的浪湧電壓。馬達之浪湧電壓之產生會導致連接於馬達之無線接收驅動裝置之基板之破損。又，存在於無線接收驅動裝置串列連接外部電池之情 形。於以此方式使用無線接收驅動裝置之情形時，若電動式玩具車之開關為接通狀態，即便為玩具車未移動之狀態，亦會向無線接收驅動裝置之基板流入外部電池之漏電流，由此有外部電池消耗之可能性。 In a state in which the wireless receiving driving device is mounted on the battery case of the toy vehicle, the motor and the external opening relationship of the toy car are connected in series with the wireless receiving driving device. With the on/off of an inductive load such as a motor, a high surge voltage due to the reverse power is generated in the motor. The generation of a surge voltage of the motor causes damage to the substrate of the wireless receiving drive connected to the motor. Moreover, the wireless receiving drive device is connected in series with an external battery. shape. When the wireless receiving drive device is used in this manner, if the switch of the electric toy vehicle is in the ON state, even if the toy vehicle is not moving, the leakage current of the external battery flows into the substrate of the wireless receiving drive device. This has the potential for external battery consumption.

The drain terminal of the output transistor 120 is connected to the outer positive terminal 103 via the distribution cable 110.

上拉電阻(檢測電阻)124係於內側正極端子105與 外側正極端子103之間，與輸出電晶體120並列地配置。上拉電阻125係介置於輸出電晶體120之閘極端子與內側正極端子105之間。 A pull-up resistor (detection resistor) 124 is connected to the inner positive terminal 105 and The outer positive electrode terminals 103 are arranged in parallel with the output transistor 120. The pull-up resistor 125 is interposed between the gate terminal of the output transistor 120 and the inner positive terminal 105.

DCDC變換器121之Vcc端子係連接於內側正極端子105，EN端子連接於外側正極端子103，OUTPUT端子連接於RFIC122之Vdd端子。DCDC變換器121係內部電源電路，將安裝於電池收納部102之單四乾電池之電池電壓Vcc升壓至內部電路動作用之例如3.0V之電源電壓Vdd。DCDC變換器121係以於上述EN端子為高位準時將電源電壓Vdd供給至RFIC122，於上述EN端子為低位準時不將電源電壓Vdd供給至RFIC122的方式構成。此處，DCDC變換器121係作為供給RFIC122之驅動電壓之內部電源電路發揮功能，但向RFIC122供給驅動電壓之內部電源電路亦可為DCDC變換器121以外之其它電子零件等。 The Vcc terminal of the DCDC converter 121 is connected to the inner positive terminal 105, the EN terminal is connected to the outer positive terminal 103, and the OUTPUT terminal is connected to the Vdd terminal of the RFIC 122. The DCDC converter 121 is an internal power supply circuit that boosts the battery voltage Vcc of the single-four-cell battery mounted in the battery housing unit 102 to a power supply voltage Vdd of, for example, 3.0 V for internal circuit operation. The DCDC converter 121 is configured to supply the power supply voltage Vdd to the RFIC 122 when the EN terminal is at a high level, and not to supply the power supply voltage Vdd to the RFIC 122 when the EN terminal is at a low level. Here, the DCDC converter 121 functions as an internal power supply circuit that supplies the driving voltage of the RFIC 122. However, the internal power supply circuit that supplies the driving voltage to the RFIC 122 may be an electronic component other than the DCDC converter 121 or the like.

於輸出電晶體120之漏極端子與DCDC變換器121之EN端子之間介置有反相器123。藉由於DCDC變換器121之輸入段配置反相器123，而可避免因馬達115產生之逆起電壓引起的DCDC變換器之破壞等。反相器123之輸入端子連接於輸出電晶體120之漏極端子，輸出端子連接於DCDC變換器121之EN端子。反相器123係將輸入信號反轉後輸出。 An inverter 123 is interposed between the drain terminal of the output transistor 120 and the EN terminal of the DCDC converter 121. By arranging the inverter 123 in the input section of the DCDC converter 121, the destruction of the DCDC converter due to the reverse voltage generated by the motor 115 and the like can be avoided. The input terminal of the inverter 123 is connected to the drain terminal of the output transistor 120, and the output terminal is connected to the EN terminal of the DCDC converter 121. The inverter 123 inverts the input signal and outputs it.

RFIC122係由電源電壓Vdd驅動而統括地控制電池式電源裝置100之控制電路。於RFIC122之ANT端子連接 有無線通訊用之天線127。RFIC122之OUTPUT端子連接於輸出電晶體120之閘極端子。RFIC122於功能上具備通訊部、控制信號產生部、控制部等。通訊部依照控制部之控制而驅動，經由天線127而與外部資訊處理裝置200進行依據Bluetooth(註冊商標)規格之無線通訊。另，RFIC122亦可進行依據其它無線通訊規格、例如無線LAN規格之無線通訊。通訊部經由天線127自外部資訊處理裝置200接收表示馬達115之接通/斷開之代碼無線信號。接收到表示馬達115接通之代碼無線信號時，控制信號產生部依照控制部之控制而驅動，產生低位準之閘極控制信號。接收到表示馬達115斷開之代碼無線信號時，控制信號產生部依照控制部之控制產生高位準之閘極控制信號。或者，控制信號產生部依照控制部之控制而斷開，由此開放OUTPUT端子。所謂控制信號產生部產生之閘極控制信號之高位準，係指相較輸出電晶體120之閾值電壓Vth充分低之電壓值，所謂低位準係指相較輸出電晶體120之閾值電壓Vth充分高之電壓值。 The RFIC 122 is controlled by the power supply voltage Vdd to collectively control the control circuit of the battery power supply device 100. Connected to the ANT terminal of RFIC122 There is an antenna 127 for wireless communication. The OUTPUT terminal of the RFIC 122 is connected to the gate terminal of the output transistor 120. The RFIC 122 functionally includes a communication unit, a control signal generation unit, and a control unit. The communication unit is driven in accordance with the control of the control unit, and performs wireless communication in accordance with the Bluetooth (registered trademark) standard with the external information processing device 200 via the antenna 127. In addition, the RFIC 122 can also perform wireless communication according to other wireless communication specifications, such as wireless LAN specifications. The communication unit receives a code wireless signal indicating ON/OFF of the motor 115 from the external information processing device 200 via the antenna 127. Upon receiving the code wireless signal indicating that the motor 115 is turned on, the control signal generating unit is driven in accordance with the control of the control unit to generate a low level gate control signal. Upon receiving the code wireless signal indicating that the motor 115 is off, the control signal generating unit generates a high level gate control signal in accordance with the control of the control unit. Alternatively, the control signal generating unit is turned off in accordance with the control of the control unit, thereby opening the OUTPUT terminal. The high level of the gate control signal generated by the control signal generating portion is a voltage value that is sufficiently lower than the threshold voltage Vth of the output transistor 120. The so-called low level refers to a threshold voltage Vth that is sufficiently higher than the output transistor 120. The voltage value.

輸出電晶體120係藉由利用輸入至閘極之閘極控制信號而施加之電壓(閘極電壓)，控制其接通/斷開。於閘極電壓相較閾值電壓Vth充分低之低位準時，於源極‧漏極間形成通道，流通最大漏極電流。該狀態係輸出電晶體120接通之狀態。若輸出電晶體120接通，則電池式電源裝置100之外側正極端子103與外側負極端子104之間經由內置電池而流通電流。若外部負載裝置111之電源開關 114為接通狀態，則電池式電源裝置100之外側正極端子103與外側負極端子104之間流通電流，外部負載裝置111之馬達115驅動。另一方面，於閘極電壓相較閾值電壓Vth充分高之高位準時，源極‧漏極間不流通漏極電流。該狀態係輸出電晶體120斷開之狀態。若輸出電晶體120斷開，則電池式電源裝置100之外側正極端子103與外側負極端子104之間遮斷。藉此，即便外部負載裝置111之電源開關114為接通狀態，外部負載裝置111之電路遮斷，馬達115不驅動。 The output transistor 120 controls its on/off by a voltage (gate voltage) applied by a gate control signal input to the gate. When the gate voltage is sufficiently lower than the threshold voltage Vth, a channel is formed between the source and the drain, and a maximum drain current flows. This state is a state in which the output transistor 120 is turned on. When the output transistor 120 is turned on, a current flows between the outer positive electrode terminal 103 and the outer negative terminal 104 of the battery type power supply device 100 via the internal battery. If the power switch of the external load device 111 When 114 is in the ON state, current flows between the external positive electrode terminal 103 and the external negative terminal 104 of the battery-type power supply device 100, and the motor 115 of the external load device 111 is driven. On the other hand, when the gate voltage is sufficiently higher than the threshold voltage Vth, the drain current does not flow between the source and the drain. This state is a state in which the output transistor 120 is turned off. When the output transistor 120 is turned off, the battery-type power supply device 100 is blocked between the outer positive terminal 103 and the outer negative terminal 104. Thereby, even if the power switch 114 of the external load device 111 is in the ON state, the circuit of the external load device 111 is blocked, and the motor 115 is not driven.

保護用二極體171係以相對於馬達115而與輸出電晶體120並列地自外側負極端子104朝外側正極端子103為順向之方式配置。曾納二極體172係與保護用二極體171朝向相反地配置。此處，保護用二極體171及曾納二極體172係於外側正極端子103與外側負極端子104之間相對於馬達115而並列連接於輸出電晶體120及內置電池。保護用二極體171之輸入端子連接於外側負極端子104，輸出端子連接於曾納二極體172之輸出端子，曾納二極體172之輸入端子連接於外側正極端子103。 The protective diode 171 is disposed so as to be parallel to the output positive transistor 120 from the outer negative terminal 104 toward the outer positive terminal 103 in parallel with the motor 115. The Zener diode 172 is disposed opposite to the protective diode 171. Here, the protective diode 171 and the Zener diode 172 are connected in parallel between the outer positive electrode terminal 103 and the outer negative terminal 104 to the output transistor 120 and the internal battery with respect to the motor 115. The input terminal of the protective diode 171 is connected to the outer negative terminal 104, the output terminal is connected to the output terminal of the Zener diode 172, and the input terminal of the Zener diode 172 is connected to the outer positive terminal 103.

曾納二極體172之曾納電壓與保護用二極體171之順向電壓之合計電壓較輸出電晶體120之逆擊穿電壓之絕對值小。藉此，伴隨輸出電晶體120之接通/斷開，即便馬達115瞬間產生浪湧電壓(逆起電壓)，浪湧電流亦會被包含保護用二極體171及馬達115之閉電路消耗。由此，可避免輸出電晶體120之汲極-源極間施加高電壓，從而 可自馬達115產生之浪湧電壓保護輸出電晶體120。 The sum of the Zener voltage of the Zener diode 172 and the forward voltage of the protective diode 171 is smaller than the absolute value of the reverse breakdown voltage of the output transistor 120. As a result, with the on/off of the output transistor 120, even if the motor 115 instantaneously generates a surge voltage (reverse voltage), the surge current is consumed by the closed circuit including the protection diode 171 and the motor 115. Thereby, a high voltage is applied between the drain and the source of the output transistor 120, thereby The output voltage 120 can be protected by a surge voltage generated from the motor 115.

又，曾納二極體172之曾納電壓與保護用二極體171之順向電壓之合計電壓至少較外部電池300之合計電壓大。藉此，於外部開關114接通之狀態下，當輸出電晶體120為穩定狀態時，即外部開關114為接通狀態下馬達115不產生浪湧電壓時，於曾納二極體172僅施加有較曾納電壓低之逆向電壓，故而曾納二極體172為斷開狀態。包含保護用二極體171及馬達115之閉電路因曾納二極體172遮斷，由此可防止或減少外部電池300之漏電流之產生。另，當外部開關114與輸出電晶體120均為接通狀態時，於保護用二極體171僅施加有較二極體之逆擊穿電壓低之逆向電壓，故而保護用二極體為斷開狀態。因此，包含輸出電晶體120、內置電池及保護用二極體171之閉電路因保護用二極體171遮斷，由此可避免內置電池之短路。 Further, the total voltage of the Zener voltage of the Zener diode 172 and the forward voltage of the protective diode 171 is at least larger than the total voltage of the external battery 300. Thereby, when the output transistor 120 is in the steady state in the state where the external switch 114 is turned on, that is, when the motor 115 does not generate a surge voltage when the external switch 114 is in the ON state, only the Zener diode 172 is applied. There is a reverse voltage lower than the Zener voltage, so the Zener diode 172 is off. The closed circuit including the protective diode 171 and the motor 115 is blocked by the Zener diode 172, whereby the occurrence of leakage current of the external battery 300 can be prevented or reduced. When both the external switch 114 and the output transistor 120 are in an ON state, only the reverse voltage lower than the reverse breakdown voltage of the diode is applied to the protection diode 171, so that the protection diode is broken. Open state. Therefore, the closed circuit including the output transistor 120, the built-in battery, and the protective diode 171 is blocked by the protective diode 171, whereby the short circuit of the built-in battery can be avoided.

(動作說明) (Action description)

以下，將電源開關114斷開之狀態稱為外部負載裝置11之斷開狀態，將電源開關114接通但馬達115不動作之狀態稱為外部負載裝置111之待機狀態，將馬達115動作之狀態稱為外部負載裝置111之動作狀態。又，將RFIC122之控制部不驅動之狀態稱為電池式電源裝置100之斷開狀態，將RFIC122之控制部驅動但無線通訊部之發送接收動作斷開之狀態稱為電池式電源裝置100之待機狀 態，將無線通訊部之發送接收動作接通之狀態稱為電池式電源裝置100之可通訊狀態，將自RFIC122輸出閘極控制信號之狀態稱為電池式電源裝置100之動作狀態。 Hereinafter, a state in which the power switch 114 is turned off is referred to as an off state of the external load device 11, and a state in which the power switch 114 is turned on but the motor 115 is not operated is referred to as a standby state of the external load device 111, and the motor 115 is operated. It is called the operating state of the external load device 111. In addition, the state in which the control unit of the RFIC 122 is not driven is referred to as the disconnected state of the battery-type power supply device 100, and the state in which the control unit of the RFIC 122 is driven but the transmission/reception operation of the wireless communication unit is turned off is referred to as standby of the battery-type power supply device 100. shape The state in which the transmission/reception operation of the wireless communication unit is turned on is referred to as the communicable state of the battery-type power supply device 100, and the state in which the gate control signal is output from the RFIC 122 is referred to as the operation state of the battery-type power supply device 100.

第1實施形態之電池式電源裝置100之一個特徵為，與電源開關114之接通/斷開連動地，以外側正極端子103之相對於基準電位之電壓位準變動之方式，於內側正極端子105與外側正極端子103之間，與輸出電晶體120並列地配置有上拉電阻(檢測電阻)124。此處，將基準電位設為GND電位。當電源開關114斷開時，外側正極端子103經由上拉電阻124連接於內側正極端子105，故而為高位準。另一方面，若電源開關114自斷開切換為接通，則外側正極端子103經由電源開關114而連接於GND，故而自高位準切換為低位準。如此，與電源開關114之接通/斷開連動地，外側正極端子103之電壓位準變動。電池式電源裝置100藉由檢測外側正極端子103之電壓位準之變動，而檢測電源開關114之接通/斷開。 The battery-type power supply device 100 according to the first embodiment is characterized in that, in conjunction with the on/off of the power switch 114, the inner positive terminal is shifted by the voltage level of the outer positive terminal 103 with respect to the reference potential. A pull-up resistor (detection resistor) 124 is disposed between the 105 and the outer positive terminal 103 in parallel with the output transistor 120. Here, the reference potential is set to the GND potential. When the power switch 114 is turned off, the outer positive terminal 103 is connected to the inner positive terminal 105 via the pull-up resistor 124, so that it is at a high level. On the other hand, when the power switch 114 is switched from off to on, the outer positive terminal 103 is connected to GND via the power switch 114, and thus switches from a high level to a low level. Thus, in conjunction with the on/off of the power switch 114, the voltage level of the outer positive terminal 103 changes. The battery type power supply device 100 detects the on/off of the power switch 114 by detecting the fluctuation of the voltage level of the outer positive terminal 103.

當外部負載裝置111為初始狀態時，反相器123之輸入端子經由上拉電阻124而連接於內側正極端子105，故而為高位準，DCDC變換器121之EN端子(反相器123之輸出端子)為低位準。因此，由DCDC變換器121產生之電源電壓Vdd不被供給至RFIC122。因此，電池式電源裝置100為斷開狀態。 When the external load device 111 is in the initial state, the input terminal of the inverter 123 is connected to the inner positive terminal 105 via the pull-up resistor 124, so it is a high level, and the EN terminal of the DCDC converter 121 (the output terminal of the inverter 123) ) is low. Therefore, the power supply voltage Vdd generated by the DCDC converter 121 is not supplied to the RFIC 122. Therefore, the battery type power supply device 100 is in an off state.

當電源開關114接通時，反相器123之輸入端子經由電源開關114而連接於GND，故而自高位準切換為低位 準，DCDC變換器121之EN端子自低位準切換為高位準。藉此，由DCDC變換器121產生之電源電壓Vdd供給至RFIC122，藉此RFIC122之控制部驅動，電池式電源裝置100之狀態自斷開狀態遷移為待機狀態。以RFIC122驅動為契機，依照控制部之控制，無線通訊部之發送接收動作自斷開切換為接通，藉此電池式電源裝置100自待機狀態遷移為可通訊狀態。 When the power switch 114 is turned on, the input terminal of the inverter 123 is connected to the GND via the power switch 114, so switching from the high level to the low level The EN terminal of the DCDC converter 121 switches from a low level to a high level. Thereby, the power supply voltage Vdd generated by the DCDC converter 121 is supplied to the RFIC 122, whereby the control unit of the RFIC 122 is driven, and the state of the battery-type power supply device 100 shifts from the disconnected state to the standby state. When the RFIC 122 is driven, the transmission/reception operation of the wireless communication unit is switched from off to on in accordance with the control of the control unit, whereby the battery-type power supply device 100 shifts from the standby state to the communicable state.

當電源開關114斷開時，反相器123之輸入端子再次經由上拉電阻124而連接於內側正極端子105，故而自低位準切換為高位準，藉此RFIC122斷開，電池式電源裝置100之狀態自可通訊狀態切換為斷開狀態。 When the power switch 114 is turned off, the input terminal of the inverter 123 is again connected to the inner positive terminal 105 via the pull-up resistor 124, and thus switches from the low level to the high level, whereby the RFIC 122 is turned off, and the battery power supply device 100 The status switches from the communicable state to the disconnected state.

當電池式電源裝置100為可通訊狀態時，電池式電源裝置100依照自外部資訊處理裝置200接收之無線信號，可進行各種處理。例如經由無線通訊部自外部資訊處理裝置200接收到指示馬達115接通之代碼無線信號時，控制信號產生部產生低位準之閘極控制信號。藉此，輸出電晶體120之閘極端子變成低位準，因此輸出電晶體120接通，馬達115驅動。如此，使用者藉由操作外部資訊處理裝置200，可以自由之時序接通外部負載裝置111。 When the battery-type power supply device 100 is in a communicable state, the battery-type power supply device 100 can perform various processes in accordance with wireless signals received from the external information processing device 200. For example, when the code wireless signal indicating that the motor 115 is turned on is received from the external information processing device 200 via the wireless communication unit, the control signal generating unit generates a low level gate control signal. Thereby, the gate terminal of the output transistor 120 becomes a low level, so that the output transistor 120 is turned on and the motor 115 is driven. In this way, by operating the external information processing device 200, the user can turn on the external load device 111 at a free timing.

如圖4所說明般，根據第1實施形態之電池式電源裝置100，可與外部負載裝置111之電源開關114之接通連動地，將電池式電源裝置100之狀態自斷開狀態切換為可通訊狀態，且與電源開關114之斷開連動地，自可通訊狀態切換為斷開狀態。藉此，電池式電源裝置100無須裝備 用於將其狀態於斷開狀態與可通訊狀態之間切換之開關，該點有助於裝置之小型化及零件成本之降低。又，當外部負載裝置111為初始狀態時，DCDC變換器121與RFIC122不驅動，故而可降低不需要之電力消耗。 As shown in FIG. 4, according to the battery-type power supply device 100 of the first embodiment, the state of the battery-type power supply device 100 can be switched from the disconnected state to the state in which the power switch 114 of the external load device 111 is turned on. The communication state is switched from the communicable state to the disconnected state in conjunction with the disconnection of the power switch 114. Thereby, the battery type power supply device 100 does not need to be equipped A switch for switching its state between an open state and a communicable state, which contributes to miniaturization of the device and reduction in component cost. Further, when the external load device 111 is in the initial state, the DCDC converter 121 and the RFIC 122 are not driven, so that unnecessary power consumption can be reduced.

另，於第1實施形態之電池式電源裝置100中，係將反相器123之輸出信號輸入至DCDC變換器121，但亦可為將反相器123之輸出信號輸入至RFIC122的構成。 In the battery-type power supply device 100 of the first embodiment, the output signal of the inverter 123 is input to the DC-DC converter 121. However, the output signal of the inverter 123 may be input to the RFIC 122.

圖5係表示第1實施形態之電池式電源裝置100之其它例之等效電路圖。反相器123之輸出端子係連接於RFIC122之INPUT端子。藉由於RFIC122之輸入段配置反相器123，可避免因馬達115產生之逆起電壓引起之RFIC122之破壞等。DCDC變換器121之EN端子係連接於內側正極端子105。因此，於內置電池安裝於電池收納部102之期間，DCDC變換器121接通，故而電池式電源裝置100為待機狀態。 Fig. 5 is an equivalent circuit diagram showing another example of the battery-type power supply device 100 of the first embodiment. The output terminal of the inverter 123 is connected to the INPUT terminal of the RFIC 122. By configuring the inverter 123 in the input section of the RFIC 122, the destruction of the RFIC 122 due to the reverse voltage generated by the motor 115 can be avoided. The EN terminal of the DCDC converter 121 is connected to the inner positive terminal 105. Therefore, while the built-in battery is mounted in the battery housing portion 102, the DCDC converter 121 is turned on, and the battery power source device 100 is in the standby state.

RFIC122依照外側正極端子103之電壓位準判別的電源開關114之接通/斷開，切換經由天線127之RF信號之發送接收動作之接通/斷開。如圖4所說明般，電源開關114之接通/斷開可根據反相器123之輸出信號之電壓位準判別。當電源開關114接通時，反相器123之輸出信號為高位準，當電源開關114斷開時，反相器123之輸出信號為低位準。因此，當INPUT端子為低位準時，判別電源開關114斷開，故而依照控制部之控制而無線通訊部之發送接收動作斷開，將電池式電源裝置100之狀態自可通訊 狀態切換為待機狀態。當INPUT端子為高位準時，判別電源開關114接通，故而依照控制部之控制而無線通訊部之發送接收動作接通，將電池式電源裝置100之狀態自待機狀態切換為可通訊狀態。控制部對無線通訊部之發送接收動作之接通/斷開之切換係藉由控制無線通訊部之通訊模組之驅動電壓Vdd之供電而進行。當然，控制部對無線通訊部之發送接收動作之接通/斷開之切換亦可於通訊模組驅動之狀態下藉由利用軟體控制電波輸出而進行。 The RFIC 122 switches ON/OFF of the transmission/reception operation of the RF signal via the antenna 127 in accordance with the on/off of the power switch 114 determined by the voltage level of the outer positive terminal 103. As illustrated in FIG. 4, the on/off of the power switch 114 can be determined based on the voltage level of the output signal of the inverter 123. When the power switch 114 is turned on, the output signal of the inverter 123 is at a high level, and when the power switch 114 is turned off, the output signal of the inverter 123 is at a low level. Therefore, when the INPUT terminal is at the low level, it is determined that the power switch 114 is turned off, so that the transmission and reception operation of the wireless communication unit is turned off in accordance with the control of the control unit, and the state of the battery type power supply device 100 is self-communicable. The state is switched to the standby state. When the INPUT terminal is at the high level, it is determined that the power switch 114 is turned on. Therefore, the transmission/reception operation of the wireless communication unit is turned on in accordance with the control of the control unit, and the state of the battery-type power supply device 100 is switched from the standby state to the communicable state. The switching of the ON/OFF of the transmission/reception operation of the wireless communication unit by the control unit is performed by controlling the power supply of the drive voltage Vdd of the communication module of the wireless communication unit. Of course, the switching of the ON/OFF of the transmission/reception operation of the wireless communication unit by the control unit can also be performed by controlling the radio wave output by the software while the communication module is being driven.

如圖5所說明般，根據第1實施形態之電池式電源裝置100之其它例，可與外部負載裝置111之電源開關114之接通連動地，將電池式電源裝置100之狀態自待機狀態切換為可通訊狀態，且與電源開關114之斷開連動地自可通訊狀態切換為待機狀態。藉此，電池式電源裝置100無須裝備用於將其狀態於待機狀態與可通訊狀態之間切換之開關，該點有助於裝置之小型化及零件成本之降低。又，當外部負載裝置111為初始狀態時，DCDC變換器121與RFIC122不驅動，故而可降低不需要之電力消耗。 As described in FIG. 5, according to another example of the battery-type power supply device 100 of the first embodiment, the state of the battery-type power supply device 100 can be switched from the standby state in conjunction with the power switch 114 of the external load device 111. It is in a communicable state, and is switched from the communicable state to the standby state in conjunction with the disconnection of the power switch 114. Thereby, the battery-type power supply device 100 does not need to be equipped with a switch for switching its state between the standby state and the communicable state, which contributes to miniaturization of the device and reduction in component cost. Further, when the external load device 111 is in the initial state, the DCDC converter 121 and the RFIC 122 are not driven, so that unnecessary power consumption can be reduced.

又，藉由如圖5般構成電路，於內置電池安裝於電池收納部102之期間，電池式電源裝置100為待機狀態。控制部亦可與電源開關114之接通/斷開連動地，執行無線通訊部之發送接收動作之接通/斷開以外之處理。例如，控制部與電源開關114之接通/斷開連動地變更外部資訊處理裝置200之間之通訊間隔。圖6係表示圖5之電池式電源裝置100對通訊間隔之變更處理之順序之流程圖。當 外部負載裝置111為初始狀態時，電池式電源裝置100為待機狀態。無線通訊部依照控制部之控制，以通訊間隔T1與外部資訊處理裝置200通訊(步驟S11)。當電源開關114接通時(步驟S12)，即RFIC122之INPUT端子自低位準切換為高位準時，無線通訊部依照控制部之控制，以較通訊間隔T1短之通訊間隔T2與外部資訊處理裝置200通訊(步驟S13)。通訊間隔T1、T2可為預設值，亦可為由使用者經由外部資訊處理裝置200設定之值。當電源開關114斷開時(步驟S14)，即RFIC122之INPUT端子自高位準切換為低位準時，處理步驟返回至步驟S11，無線通訊部依照控制部之控制，以通訊間隔T1與外部資訊處理裝置200通訊。 Further, by configuring the circuit as shown in FIG. 5, the battery-type power supply device 100 is in a standby state while the internal battery is mounted in the battery housing portion 102. The control unit may perform processing other than the on/off of the transmission/reception operation of the wireless communication unit in conjunction with the on/off of the power switch 114. For example, the control unit changes the communication interval between the external information processing devices 200 in conjunction with the on/off of the power switch 114. Fig. 6 is a flow chart showing the procedure of the process of changing the communication interval by the battery-type power supply device 100 of Fig. 5. when When the external load device 111 is in the initial state, the battery-type power supply device 100 is in the standby state. The wireless communication unit communicates with the external information processing device 200 at the communication interval T1 in accordance with the control of the control unit (step S11). When the power switch 114 is turned on (step S12), that is, when the INPUT terminal of the RFIC 122 is switched from the low level to the high level, the wireless communication unit is in communication with the external information processing device 200 at a communication interval T2 shorter than the communication interval T1 according to the control of the control unit. Communication (step S13). The communication intervals T1 and T2 may be preset values or may be values set by the user via the external information processing device 200. When the power switch 114 is turned off (step S14), that is, when the INPUT terminal of the RFIC 122 is switched from the high level to the low level, the processing returns to step S11, and the wireless communication unit controls the communication unit to communicate with the external information processing device according to the control interval. 200 communications.

當外部負載裝置111為待機狀態時，藉由縮短外部資訊處理裝置200之間之通訊間隔，提升電池式電源裝置100對來自外部資訊處理裝置200之指示之應答速度，且亦可提升外部資訊處理裝置200之間之通訊之連接性。又，當外部負載裝置111為斷開狀態(電源開關114為斷開狀態)時，藉由延長外部資訊處理裝置200之間之通訊間隔，可降低不需要之電力消耗。 When the external load device 111 is in the standby state, by shortening the communication interval between the external information processing devices 200, the response speed of the battery-type power supply device 100 to the instruction from the external information processing device 200 is improved, and external information processing can also be improved. Connectivity of communication between devices 200. Further, when the external load device 111 is in the off state (the power switch 114 is in the off state), by extending the communication interval between the external information processing devices 200, unnecessary power consumption can be reduced.

(第2實施形態) (Second embodiment)

第2實施形態之電池式電源裝置100係構成為可使用PWM信號作為第1實施形態之電池式電源裝置100之輸出電晶體120之閘極控制信號。 The battery-type power supply device 100 of the second embodiment is configured to use a PWM signal as a gate control signal of the output transistor 120 of the battery-type power supply device 100 of the first embodiment.

(電路構成) (circuit configuration)

圖7係表示第2實施形態之電池式電源裝置100之一例之等效電路圖。第2實施形態之電池式電源裝置100之一個特徵為，於DCDC變換器121之EN端子之前段配置OR電路131。於第2實施形態之電池式電源裝置100中，保護用二極體171及曾納二極體172係與第1實施形態之電池式電源裝置100同樣地連接，藉此發揮與第1實施形態相同之效果。 Fig. 7 is an equivalent circuit diagram showing an example of the battery-type power supply device 100 of the second embodiment. One of the battery-type power supply devices 100 of the second embodiment is characterized in that the OR circuit 131 is disposed in front of the EN terminal of the DC-DC converter 121. In the battery-type power supply device 100 of the second embodiment, the protective diode 171 and the Zener diode 172 are connected in the same manner as the battery-type power supply device 100 of the first embodiment, thereby exhibiting the first embodiment. The same effect.

OR電路131具有2個輸入端子及1個輸出端子。OR電路131於其2個輸入端子中之至少一者為高位準時，輸出高位準之信號。又，OR電路131於其2個輸入端子之兩方為低位準時，輸出低位準之信號。OR電路131之輸出端子連接於DCDC變換器121之EN端子。OR電路131之輸出端子與DCDC變換器121之EN端子之間介置有低通濾波器132。低通濾波器132包含例如電阻及電容器。低通濾波器132使較遮斷頻率低之頻率之成分通過，遞減較遮斷頻率高之頻率之成分，抑制因雜訊等引起之瞬間信號之變動。 The OR circuit 131 has two input terminals and one output terminal. The OR circuit 131 outputs a signal of a high level when at least one of its two input terminals is at a high level. Further, the OR circuit 131 outputs a signal of a low level when both of the two input terminals are low. The output terminal of the OR circuit 131 is connected to the EN terminal of the DCDC converter 121. A low pass filter 132 is interposed between the output terminal of the OR circuit 131 and the EN terminal of the DCDC converter 121. The low pass filter 132 includes, for example, a resistor and a capacitor. The low-pass filter 132 passes a component having a frequency lower than the cutoff frequency, reduces a component having a frequency higher than the cutoff frequency, and suppresses a change in an instantaneous signal caused by noise or the like.

OR電路131之一輸入端子(第1輸入端子)連接於RFIC122之OUTPUT端子。OR電路131之另一輸入端子(第2輸入端子)經由檢測電晶體130連接於內側正極端子105。又，OR電路131之第1、第2輸入端子經由下拉電阻136、135而連接於GND。 One input terminal (first input terminal) of the OR circuit 131 is connected to the OUTPUT terminal of the RFIC 122. The other input terminal (second input terminal) of the OR circuit 131 is connected to the inner positive terminal 105 via the detecting transistor 130. Further, the first and second input terminals of the OR circuit 131 are connected to GND via pull-down resistors 136 and 135.

RFIC122之OUTPUT端子與輸出電晶體120之閘極端子之間介置有反相器133。反相器133之輸出係輸入至輸出電晶體120之閘極。 An inverter 133 is interposed between the OUTPUT terminal of the RFIC 122 and the gate terminal of the output transistor 120. The output of inverter 133 is input to the gate of output transistor 120.

檢測電晶體130典型而言係P通道MOSFET，對電源開關114之接通/斷開進行檢測。檢測電晶體130之漏極端子連接於OR電路131之第2輸入端子，源極端子連接於內側正極端子105，閘極端子連接於外側正極端子103。與第1實施形態同樣地，上拉電阻(檢測電阻)124係於內側正極端子105與外側正極端子103之間，與輸出電晶體120並列地配置。藉此，可與電源開關114之接通/斷開連動地，將外側正極端子103之信號位準於低位準與高位準之間切換。藉由將檢測電晶體130之閘極端子連接於外側正極端子103，可與電源開關114之接通/斷開連動地將檢測電晶體130接通/斷開。 The detection transistor 130 is typically a P-channel MOSFET that detects the on/off of the power switch 114. The drain terminal of the detecting transistor 130 is connected to the second input terminal of the OR circuit 131, the source terminal is connected to the inner positive terminal 105, and the gate terminal is connected to the outer positive terminal 103. Similarly to the first embodiment, the pull-up resistor (detection resistor) 124 is disposed between the inner positive electrode terminal 105 and the outer positive electrode terminal 103, and is arranged in parallel with the output transistor 120. Thereby, the signal level of the outer positive terminal 103 can be switched between the low level and the high level in conjunction with the on/off of the power switch 114. By connecting the gate terminal of the detecting transistor 130 to the outer positive terminal 103, the detecting transistor 130 can be turned on/off in conjunction with the on/off of the power switch 114.

控制信號產生部依照控制部之控制，產生與接收之馬達輸出指示值相應之閘極控制信號。此處，閘極控制信號係由PWM(脈寬信號調製)信號提供。例如，於馬達輸出指示值為0%之情形時，控制信號產生部產生佔空比0%(僅低位準)之PWM信號。於馬達輸出指示值為100%之情形時，控制信號產生部產生佔空比100%(僅高位準)之PWM信號。於馬達輸出指示值為50%之情形時，控制信號產生部產生佔空比50%(低位準與高位準各一半)之信號。由控制信號產生部產生之PWM信號作為閘極控制信號輸入至輸出電晶體120。 The control signal generating unit generates a gate control signal corresponding to the received motor output instruction value in accordance with the control of the control unit. Here, the gate control signal is provided by a PWM (Pulse Width Signal Modulation) signal. For example, when the motor output indication value is 0%, the control signal generating section generates a PWM signal having a duty ratio of 0% (low level only). In the case where the motor output indicating value is 100%, the control signal generating portion generates a PWM signal having a duty ratio of 100% (high level only). In the case where the motor output indicating value is 50%, the control signal generating portion generates a signal having a duty ratio of 50% (half of the low level and the high level). The PWM signal generated by the control signal generating portion is input to the output transistor 120 as a gate control signal.

當PWM信號為高位準(閘極端子為低位準)時，輸出電晶體120為接通狀態。因此，外部負載裝置111之電路導通，馬達115驅動。當PWM信號(閘極控制信號)為低位準(閘極端子為高位準)時，輸出電晶體120為斷開狀態。因此，外部負載裝置111之電路遮斷，馬達115不驅動。於PWM信號輸入至閘極端子之期間，馬達115以特定之周期重複進行轉動開始與轉動停止。若輸出電晶體120自接通切換為斷開，馬達115因其線圈特性而轉動逐漸變慢，但若輸出電晶體120自接通切換為斷開則再次轉動變快。利用該特性，藉由PWM控制而可使馬達115以任意轉動數轉動。 When the PWM signal is at a high level (the gate terminal is at a low level), the output transistor 120 is in an on state. Therefore, the circuit of the external load device 111 is turned on, and the motor 115 is driven. When the PWM signal (gate control signal) is at a low level (the gate terminal is at a high level), the output transistor 120 is in an off state. Therefore, the circuit of the external load device 111 is blocked, and the motor 115 is not driven. During the input of the PWM signal to the gate terminal, the motor 115 repeats the rotation start and the rotation stop at a specific cycle. If the output transistor 120 is switched from on to off, the motor 115 gradually becomes slower due to its coil characteristics, but if the output transistor 120 is switched from on to off, the rotation becomes faster again. With this characteristic, the motor 115 can be rotated by an arbitrary number of rotations by PWM control.

(動作說明) (Action description)

第2實施形態之電池式電源裝置100之一個特徵為，於DCDC變換器121之前段配置有OR電路131。OR電路131接受自RFIC122輸出之閘極控制信號及檢測電晶體130之檢測信號之輸入，作為邏輯和之運算結果而向DCDC變換器121輸出高位準或低位準之信號。藉此，若電源開關114為接通狀態，可避免電池式電源裝置100自可通訊狀態切換為斷開狀態或待機狀態。 One of the battery-type power supply devices 100 of the second embodiment is characterized in that an OR circuit 131 is disposed in front of the DC-DC converter 121. The OR circuit 131 receives the input of the gate control signal output from the RFIC 122 and the detection signal of the detection transistor 130, and outputs a signal of a high level or a low level to the DCDC converter 121 as a result of the logical sum operation. Thereby, if the power switch 114 is in the on state, the battery-type power supply device 100 can be prevented from switching from the communicable state to the off state or the standby state.

具體而言，當外部負載裝置111為初始狀態時，檢測電晶體130、RFIC122亦均斷開，故而OR電路131之第1、第2輸入端子分別經由下拉電阻136、135連接於GND，故而為低位準。因此，由DCDC變換器121產生之 電源電壓Vdd不會供給至RFIC122。因此，電池式電源裝置100為斷開狀態。 Specifically, when the external load device 111 is in the initial state, the detection transistor 130 and the RFIC 122 are also turned off. Therefore, the first and second input terminals of the OR circuit 131 are connected to the GND via the pull-down resistors 136 and 135, respectively. Low level. Therefore, it is generated by the DCDC converter 121. The power supply voltage Vdd is not supplied to the RFIC 122. Therefore, the battery type power supply device 100 is in an off state.

當電源開關114接通時，檢測電晶體130之閘極端子經由電源開關114連接於GND，故而自高位準切換為低位準。OR電路131之第2輸入端子經由檢測電晶體130連接於內側正極端子105而自低位準切換為高位準，藉此OR電路131輸出高位準之信號。DCDC變換器121之EN端子自低位準切換為高位準，由DCDC變換器121產生之電源電壓Vdd供給至RFIC122，藉此RFIC122之控制部驅動，電池式電源裝置100之狀態自斷開狀態切換為待機狀態。以RFIC122之控制部驅動為契機，依照控制部之控制，無線通訊部之發送接收動作自斷開切換為接通，電池式電源裝置100之狀態自待機狀態切換為可通訊狀態。輸出電晶體120依照與來自外部資訊處理裝置200之馬達輸出指示相應的PWM信號調整其電源輸出。 When the power switch 114 is turned on, the gate terminal of the detecting transistor 130 is connected to the GND via the power switch 114, so that it switches from the high level to the low level. The second input terminal of the OR circuit 131 is connected to the inner positive terminal 105 via the detecting transistor 130, and is switched from the low level to the high level, whereby the OR circuit 131 outputs a high level signal. The EN terminal of the DCDC converter 121 is switched from the low level to the high level, and the power supply voltage Vdd generated by the DCDC converter 121 is supplied to the RFIC 122, whereby the control unit of the RFIC 122 is driven, and the state of the battery power supply device 100 is switched from the off state to standby mode. When the control unit of the RFIC 122 is driven, the transmission/reception operation of the wireless communication unit is switched from off to on in accordance with the control of the control unit, and the state of the battery-type power supply device 100 is switched from the standby state to the communicable state. The output transistor 120 adjusts its power output in accordance with a PWM signal corresponding to the motor output indication from the external information processing device 200.

於電源開關114接通之狀態下，當輸出電晶體120斷開時(輸出電晶體120之閘極端子為高位準時)，檢測電晶體130之閘極端子經由電源開關114連接於GND故而為低位準，藉此檢測電晶體130接通。藉由檢測電晶體130接通，OR電路131之第1輸入端子經由檢測電晶體130連接於內側正極端子105故而為高位準，藉此OR電路131將高位準之信號輸出至DCDC變換器121。 In a state where the power switch 114 is turned on, when the output transistor 120 is turned off (when the gate terminal of the output transistor 120 is at a high level), the gate terminal of the detecting transistor 130 is connected to the GND via the power switch 114, thereby being low. Precisely, thereby detecting that the transistor 130 is turned on. When the detecting transistor 130 is turned on, the first input terminal of the OR circuit 131 is connected to the inner positive terminal 105 via the detecting transistor 130, so that it is at a high level, whereby the OR circuit 131 outputs a high level signal to the DCDC converter 121.

於電源開關114接通之狀態下，當輸出電晶體120接通時(輸出電晶體120之閘極端子為低位準時)，檢測電 晶體130之閘極端子經由輸出電晶體120連接於內側正極端子105故而為高位準，藉此檢測電晶體130斷開。OR電路131之第1輸入端子經由下拉電阻136連接於GND故而為低位準。另一方面，當輸出電晶體120接通時，自OUTPUT端子輸出之閘極控制信號為高位準。因此，OR電路131之第2輸入端子連接於OUTPUT端子故而為高位準，藉此OR電路131將高位準之信號輸出至DCDC變換器121。 In a state where the power switch 114 is turned on, when the output transistor 120 is turned on (when the gate terminal of the output transistor 120 is at a low level), the detection is performed. The gate terminal of the crystal 130 is connected to the inner positive terminal 105 via the output transistor 120, so that it is at a high level, thereby detecting that the transistor 130 is turned off. The first input terminal of the OR circuit 131 is connected to the GND via the pull-down resistor 136, so that it is at a low level. On the other hand, when the output transistor 120 is turned on, the gate control signal output from the OUTPUT terminal is at a high level. Therefore, the second input terminal of the OR circuit 131 is connected to the OUTPUT terminal, so that it is at a high level, whereby the OR circuit 131 outputs a high level signal to the DCDC converter 121.

因此，因閘極控制信號而輸出電晶體120斷開之期間，OR電路131之第1輸入端子為高位準、第2輸入端子為低位準，故而OR電路131輸出高位準之信號。另一方面，於輸出電晶體120接通之期間，OR電路131之第1輸入端子為低位準、第2輸入端子為高位準，故而OR電路131輸出高位準之信號。 Therefore, during the period in which the output transistor 120 is turned off due to the gate control signal, the first input terminal of the OR circuit 131 is at the high level and the second input terminal is at the low level, so the OR circuit 131 outputs a high level signal. On the other hand, during the period in which the output transistor 120 is turned on, the first input terminal of the OR circuit 131 is at the low level and the second input terminal is at the high level, so the OR circuit 131 outputs a signal of a high level.

如此，若電源開關114接通，則即便輸出電晶體120因閘極控制信號而接通/斷開，OR電路131亦可維持接通狀態。藉此，於閘極控制信號使用PWM信號之情形時，亦可將電池式電源裝置100之狀態維持可通訊狀態。藉由能夠使用PWM信號，可提供一種能夠於0%至100%之範圍內自如地調整電源輸出之電源裝置。藉此，例如僅藉由將第2實施形態之電池式電源裝置100安裝於電池盒112，便可對原本不具備調整電源輸出之手段之外部負載裝置111賦予調整電源輸出之手段。使用者操作外部資訊處理裝置200，可自由地變更例如安裝電池式電源裝置 100之電動玩具之動作速度。 As described above, when the power switch 114 is turned on, the OR circuit 131 can be maintained in the ON state even if the output transistor 120 is turned on/off by the gate control signal. Thereby, when the PWM signal is used as the gate control signal, the state of the battery power supply device 100 can be maintained in a communicable state. By being able to use the PWM signal, it is possible to provide a power supply device capable of freely adjusting the power output from 0% to 100%. As a result, for example, only by attaching the battery-type power supply device 100 of the second embodiment to the battery case 112, it is possible to provide a means for adjusting the power supply output to the external load device 111 that does not have a means for adjusting the power output. The user operates the external information processing device 200, and can freely change, for example, a battery-type power supply device. The speed of the electric toy of 100.

另，於第2實施形態中，構成為將OR電路131之輸出信號輸入至DCDC變換器121，但亦可構成為將OR電路131之輸出信號輸入至RFIC122之INPUT端子，依照INPUT端子之信號位準，藉由控制部切換無線通訊部之發送接收動作之接通/斷開。 Further, in the second embodiment, the output signal of the OR circuit 131 is input to the DCDC converter 121, but the output signal of the OR circuit 131 may be input to the INPUT terminal of the RFIC 122 in accordance with the signal bit of the INPUT terminal. The control unit switches the ON/OFF of the transmission/reception operation of the wireless communication unit.

(第3實施形態) (Third embodiment)

於第1、第2實施形態中，對輸出電晶體120使用P通道MOSFET之情形時之電路例進行了說明，但作為輸出電晶體120亦可使用N通道MOSFET。相比P通道MOSFET而言，N通道MOSFET較廉價，藉由使用N通道MOSFET，可降低電池式電源裝置100之零件成本。又，相比P通道MOSFET而言，N通道MOSFET之耐壓較高，藉由使用N通道MOSFET，可增加能夠相對於電池式電源裝置100串列連接之外部電池之數。該點可期待能夠使用電池式電源裝置100之外部負載裝置111之範圍之擴大。另，輸出電晶體120亦可為雙極電晶體，於此情形時，將閘極控制信號換成基極控制信號之說法。 In the first and second embodiments, a circuit example in the case where a P-channel MOSFET is used as the output transistor 120 has been described. However, an N-channel MOSFET may be used as the output transistor 120. N-channel MOSFETs are less expensive than P-channel MOSFETs, and the cost of parts for battery-powered power supply unit 100 can be reduced by using N-channel MOSFETs. Moreover, the N-channel MOSFET has a higher withstand voltage than the P-channel MOSFET, and by using an N-channel MOSFET, the number of external batteries that can be connected in series with the battery-type power supply device 100 can be increased. At this point, it is expected that the range of the external load device 111 of the battery type power supply device 100 can be expanded. Alternatively, the output transistor 120 can also be a bipolar transistor, in which case the gate control signal is replaced by a base control signal.

(電路構成) (circuit configuration)

圖9係表示第3實施形態之電池式電源裝置100之一例之等效電路圖。圖9係將圖7之電路之輸出電晶體140自P通道MOSFET變更為N通道MOSFET之情形時之電 路例。於第3實施形態之電池式電源裝置100中，保護用二極體171及曾納二極體172係與第1實施形態之電池式電源裝置100同樣地連接，藉此發揮與第1實施形態相同之效果。 Fig. 9 is an equivalent circuit diagram showing an example of the battery-type power supply device 100 of the third embodiment. Figure 9 is a diagram showing the case where the output transistor 140 of the circuit of Figure 7 is changed from a P-channel MOSFET to an N-channel MOSFET. Road example. In the battery-type power supply device 100 of the third embodiment, the protective diode 171 and the Zener diode 172 are connected in the same manner as the battery-type power supply device 100 of the first embodiment, thereby exhibiting the first embodiment. The same effect.

如圖9所示，OR電路131、DCDC變換器121及RFIC122之間之配線係與圖7之電路相同。輸出電晶體140介置於內側負極端子106與外側負極端子104之間。輸出電晶體140之源極端子連接於內側正極端子105，漏極端子連接於外側負極端子104，閘極端子連接於RFIC122之OUTPUT端子。 As shown in FIG. 9, the wiring between the OR circuit 131, the DCDC converter 121, and the RFIC 122 is the same as that of the circuit of FIG. The output transistor 140 is interposed between the inner negative terminal 106 and the outer negative terminal 104.

(動作說明) (Action description)

當外部負載裝置111為初始狀態(電源開關114為斷開狀態)時，第2檢測電晶體141其閘極端子經由下拉電阻143連接於GND故而為低位準，而為斷開狀態。第1檢測電晶體130其閘極端子經由上拉電阻134連接於內側正極端子105故而為高位準，而為斷開狀態。於外部負載裝置111為初始狀態下RFIC122不驅動，故而不輸出閘極控制信號。因此，OR電路131其第1、第2輸入端子分別經由下拉電阻136、135連接於GND故而為低位準，故而輸出低位準之信號。 When the external load device 111 is in the initial state (the power switch 114 is in the off state), the gate terminal of the second detecting transistor 141 is connected to the GND via the pull-down resistor 143, so that it is in the off state. The first detecting transistor 130 has its gate terminal connected to the inner positive terminal 105 via the pull-up resistor 134, so that it is at a high level and is in an off state. When the external load device 111 is in the initial state, the RFIC 122 is not driven, so the gate control signal is not output. Therefore, the OR circuit 131 has its first and second input terminals connected to the GND via the pull-down resistors 136 and 135, and thus has a low level, so that a low level signal is output.

當電源開關114接通時，第2檢測電晶體141其閘極端子經由外側負極端子104、馬達115、電源開關114、外側正極端子103連接於內側正極端子105而為高位準，故而接通。第1檢測電晶體130其閘極端子經由第2檢測電晶體141連接於GND而為低位準，故而接通。OR電路131之第2輸入端子經由第1檢測電晶體130連接於內側正極端子105而自低位準切換為高位準，藉此OR電路131輸出高位準之信號。DCDC變換器121之EN端子自低位準切換為高位準，由DCDC變換器121產生之電源電壓Vdd被供給至RFIC122，藉此RFIC122之控制部驅 動，電池式電源裝置100之狀態自斷開狀態切換為待機狀態。以RFIC122之控制部驅動為契機，依照控制部之控制，無線通訊部之發送接收動作自斷開切換為接通，電池式電源裝置100之狀態自待機狀態切換為可通訊狀態。輸出電晶體120依照與來自外部資訊處理裝置200之馬達輸出指示相應的PWM信號調整其電源輸出。 When the power switch 114 is turned on, the gate terminal of the second detecting transistor 141 is connected to the inner positive terminal 105 via the outer negative terminal 104, the motor 115, the power switch 114, and the outer positive terminal 103, and is turned to the high level. The gate of the first detecting transistor 130 is connected to the GND via the second detecting transistor 141 to be at a low level, and is turned on. The second input terminal of the OR circuit 131 is connected to the inner positive terminal 105 via the first detecting transistor 130, and is switched from the low level to the high level, whereby the OR circuit 131 outputs a high level signal. The EN terminal of the DCDC converter 121 is switched from the low level to the high level, and the power supply voltage Vdd generated by the DCDC converter 121 is supplied to the RFIC 122, whereby the control unit of the RFIC 122 drives The state of the battery-type power supply device 100 is switched from the off state to the standby state. When the control unit of the RFIC 122 is driven, the transmission/reception operation of the wireless communication unit is switched from off to on in accordance with the control of the control unit, and the state of the battery-type power supply device 100 is switched from the standby state to the communicable state. The output transistor 120 adjusts its power output in accordance with a PWM signal corresponding to the motor output indication from the external information processing device 200.

根據以上所說明之第3實施形態之電池式電源裝置100，可與電源開關114之接通/斷開連動地，將其狀態於斷開狀態與可通訊狀態之間切換。又，若電源開關114接通，則即便輸出電晶體120因閘極控制信號而接通/斷開，OR電路131亦可維持接通狀態。藉此，即便於閘極控制信號使用PWM信號之情形時，亦可將電池式電源裝置100之狀態維持可通訊狀態。即，於輸出電晶體120使用N通道MOSFET之情形時，可與輸出電晶體120使用P通道MOSFET之第2實施形態之電池式電源裝置100同樣地動作，從而獲得同樣之效果。 According to the battery-type power supply device 100 of the third embodiment described above, it is possible to switch the state between the off state and the communicable state in conjunction with the on/off of the power switch 114. Further, when the power switch 114 is turned on, the OR circuit 131 can be kept in the ON state even if the output transistor 120 is turned on/off by the gate control signal. Thereby, even when the PWM signal is used as the gate control signal, the state of the battery-type power supply device 100 can be maintained in a communicable state. In other words, when the output transistor 120 is an N-channel MOSFET, the output transistor 120 can be operated in the same manner as the battery-type power supply device 100 of the second embodiment of the P-channel MOSFET, and the same effect can be obtained.

(動作說明) (Action description)

圖11係表示圖10之RFIC122之PWM控制中之各端子之輸入輸出之變化的時序圖。圖12係表示圖10之RFIC122之發送接收動作之接通/斷開之切換處理之順序的流程圖。控制部依照由控制信號產生部產生之自OUTPUT端子輸出之閘極控制信號與輸入至INPUT端子之信號的邏輯和，控制無線通訊部之發送接收動作之接通/斷開。具體而言，控制部於自OUTPUT端子輸出之閘極控制信號與輸入至INPUT端子之信號之邏輯和為高位準時接通發送接收動作，於低位準時斷開。 Fig. 11 is a timing chart showing changes in input and output of respective terminals in the PWM control of the RFIC 122 of Fig. 10. Fig. 12 is a flow chart showing the procedure of the switching processing of the ON/OFF of the transmission/reception operation of the RFIC 122 of Fig. 10. The control unit controls on/off of the transmission/reception operation of the wireless communication unit in accordance with the logical sum of the gate control signal output from the OUTPUT terminal generated by the control signal generating unit and the signal input to the INPUT terminal. Specifically, the control unit turns on the transmission/reception operation when the logical sum of the gate control signal output from the OUTPUT terminal and the signal input to the INPUT terminal is high, and turns off at the low level.

如圖12所示，當外部負載裝置111為初始狀態(電源開關114為斷開狀態)時，RFIC122之INPUT端子為低位準，OUTPUT端子為低位準(步驟S21)。因此，該等2個端子之信號位準之邏輯和為低位準，故而無線通訊部之發送接收動作不接通。因此，電池式電源裝置100為發送接收動作斷開之待機狀態。當INPUT端子自低位準切換為高位準時，即電源開關114接通時(步驟S22)，該等2個端子之信號位準之邏輯和自低位準切換為高位準。藉此，依照控制部之控制，無線通訊部之發送接收動作接通，電池式電源裝置100之狀態自待機狀態切換為可通訊狀態(步驟S23)。 As shown in FIG. 12, when the external load device 111 is in the initial state (the power switch 114 is in the off state), the INPUT terminal of the RFIC 122 is at the low level and the OUTPUT terminal is at the low level (step S21). Therefore, the logical sum of the signal levels of the two terminals is a low level, and therefore the transmission and reception operations of the wireless communication unit are not turned on. Therefore, the battery type power supply device 100 is in a standby state in which the transmission/reception operation is disconnected. When the INPUT terminal is switched from the low level to the high level, that is, when the power switch 114 is turned on (step S22), the logic level of the signal levels of the two terminals is switched from the low level to the high level. Thereby, according to the control of the control unit, the transmission/reception operation of the wireless communication unit is turned on, and the state of the battery-type power supply device 100 is switched from the standby state to the communicable state (step S23).

當INPUT端子為高位準時(步驟S24之Yes)，依照 控制部之控制，將無線通訊部之發送接收動作維持接通狀態，藉此電池式電源裝置100維持可通訊狀態(步驟S26)。當INPUT端子為低位準時，控制部依照OUTPUT端子之信號位準，切換發送接收動作之接通/斷開。當INPUT端子為低位準、OUTPUT端子為高位準時，藉由閘極控制信號之高位準而為輸出電晶體120接通，馬達115驅動之狀態。因此，電池式電源裝置100可維持可通訊狀態。因此，當INPUT端子為低位準(步驟S24之No)、OUTPUT端子為高位準時(步驟S25之Yes)，依照控制部之控制，無線通訊部之發送接收動作維持接通狀態，藉此電池式電源裝置100維持可通訊狀態(步驟S26)。當INPUT端子為低位準、OUTPUT端子為低位準時(或者開放時)，電源開關114為斷開狀態，自降低不需要之電力消耗之觀點而言，可將電池式電源裝置100自可通訊狀態切換為待機狀態。因此，當INPUT端子為低位準(步驟S24之No)、OUTPUT端子為低位準時(步驟S25之No)，依照控制部之控制，無線通訊部之發送接收動作自接通切換為斷開，藉此電池式電源裝置100之狀態自可通訊狀態切換為待機狀態(步驟S27)。 When the INPUT terminal is at the high level (Yes in step S24), The control of the control unit maintains the transmission/reception operation of the wireless communication unit in an ON state, whereby the battery-type power supply device 100 maintains the communicable state (step S26). When the INPUT terminal is at the low level, the control unit switches the transmission/reception operation on/off according to the signal level of the OUTPUT terminal. When the INPUT terminal is at the low level and the OUTPUT terminal is at the high level, the output transistor 120 is turned on by the high level of the gate control signal, and the motor 115 is driven. Therefore, the battery type power supply device 100 can maintain a communicable state. Therefore, when the INPUT terminal is at the low level (No in step S24) and the OUTPUT terminal is at the high level (Yes in step S25), the transmission and reception operation of the wireless communication unit is maintained in the ON state in accordance with the control of the control unit, whereby the battery power source is used. The device 100 maintains a communicable state (step S26). When the INPUT terminal is at a low level and the OUTPUT terminal is at a low level (or when it is open), the power switch 114 is in an off state, and the battery type power supply device 100 can be switched from a communicable state from the viewpoint of reducing unnecessary power consumption. It is in standby mode. Therefore, when the INPUT terminal is at the low level (No in step S24) and the OUTPUT terminal is at the low level (No in step S25), the transmission/reception operation of the wireless communication unit is switched from on to off in accordance with the control of the control unit. The state of the battery type power supply device 100 is switched from the communicable state to the standby state (step S27).

藉由以上所說明之控制部之發送接收動作之接通/斷開之切換控制，如圖11所示，可於電源開關114斷開之期間，斷開發送接收動作，於電源開關114接通之期間，接通發送接收動作。因此，第4實施形態之電池式電源裝置100可不用如第2實施形態般配置OR電路131地，於 零件件數少於第2實施形態之電池式電源裝置100之狀態下，使用PWM信號作為閘極控制信號。另，此處係與電源開關114之接通/斷開連動地將電池式電源裝置100之通訊功能接通/斷開，但亦可如圖5所說明般，與電源開關114之接通/斷開連動變更電池式電源裝置100之通訊間隔。例如，藉由於電源開關114為接通狀態時縮短通訊間隔，可提升電池式電源裝置100對來自外部資訊處理裝置200之指示之應答速度，且亦可提升外部資訊處理裝置200之間之通訊之連接性。又，於電源開關114斷開之狀態下，延長外部資訊處理裝置200之間之通訊間隔，藉此可降低不需要之電力消耗。 By the switching control of the ON/OFF of the transmission/reception operation of the control unit described above, as shown in FIG. 11, the transmission/reception operation can be turned off while the power switch 114 is off, and the power switch 114 is turned on. During this period, the transmission and reception operation is turned on. Therefore, the battery-type power supply device 100 of the fourth embodiment can be configured without the OR circuit 131 as in the second embodiment. When the number of parts is smaller than that of the battery type power supply device 100 of the second embodiment, the PWM signal is used as the gate control signal. In addition, the communication function of the battery-type power supply device 100 is turned on/off in conjunction with the on/off of the power switch 114, but may be connected to the power switch 114 as illustrated in FIG. The communication interval of the battery type power supply device 100 is changed by the disconnection. For example, by shortening the communication interval when the power switch 114 is in the on state, the response speed of the battery power source device 100 to the instruction from the external information processing device 200 can be improved, and the communication between the external information processing devices 200 can also be improved. Connectivity. Further, in a state where the power switch 114 is turned off, the communication interval between the external information processing devices 200 is extended, whereby unnecessary power consumption can be reduced.

又，對控制部之發送接收動作之接通/斷開之切換進行控制之方法並不限定於上述。例如，控制部亦可於自OUTPUT端子輸出閘極控制信號之期間不進行無線通訊部之發送接收動作之接通/斷開控制。藉此，即便因閘極控制信號而輸出電晶體120接通/斷開，INPUT端子之輸入信號之電壓位準發生變化，電池式電源裝置100亦可維持即將自OUTPUT端子輸出閘極控制信號前之狀態、即可通訊狀態。 Moreover, the method of controlling the switching of the ON/OFF of the transmission/reception operation of the control unit is not limited to the above. For example, the control unit may not perform ON/OFF control of the transmission/reception operation of the wireless communication unit while the gate control signal is output from the OUTPUT terminal. Thereby, even if the output transistor 120 is turned on/off due to the gate control signal, the voltage level of the input signal of the INPUT terminal changes, and the battery type power supply device 100 can maintain the gate control signal immediately before output from the OUTPUT terminal. The status, the communication status.

When the OUTPUT2 terminal of the RFIC 122 is open, in order to stabilize the gate terminal of the third output transistor 163 at a high level, the gate terminal of the third output transistor 163 is connected to the inner positive terminal 105 via the pull-up resistor 153.

第4輸出電晶體164之源極端子連接於內側負極端子106，漏極端子連接於外側負極端子104，閘極端子連接於RFIC122之OUTPUT1端子。當RFIC122之OUTPUT1端子開放時，為了以高位準穩定第4輸出電晶體164之閘極端子，第4輸出電晶體164之閘極端子經由上拉電阻154連接於內側正極端子105。 The source terminal of the fourth output transistor 164 is connected to the inner negative terminal 106, the drain terminal is connected to the outer negative terminal 104, and the gate terminal is connected to the OUTPUT1 terminal of the RFIC 122. When the OUTPUT1 terminal of the RFIC 122 is open, in order to stabilize the gate terminal of the fourth output transistor 164 at a high level, the gate terminal of the fourth output transistor 164 is connected to the inner positive terminal 105 via the pull-up resistor 154.

於OR電路131之第1輸入端子之前段配置有OR電路145。OR電路145之第1輸入端子連接於RFIC122之OUTPUT1端子，第2輸入端子連接於RFIC122之 OUTPUT2端子。藉此，若自OUTPUT1端子與OUTPUT2端子之一方輸出有閘極控制信號，則即便於OUTPUT端子有2個之情形時，亦可與第2實施形態同樣地自OUTPUT1端子或OUTPUT2端子輸出高位準之閘極控制信號，無論於第1、第4輸出電晶體161、164接通之情形時、還是第2、第3輸出電晶體162、163接通之情形時，均可維持電池式電源裝置100之發送接收動作接通之狀態。因此，可使用PWM信號作為閘極控制信號。 An OR circuit 145 is disposed in front of the first input terminal of the OR circuit 131.

(電路動作) (circuit action)

圖14係表示伴隨圖13之電源開關114之接通/斷開而變動之各電晶體之端子電壓的圖。 Fig. 14 is a view showing terminal voltages of the respective transistors which are changed in accordance with the on/off of the power switch 114 of Fig. 13;

於電源開關114斷開之狀態下，第1、第3輸出電晶體161、163其等之源極端子為高位準、其等之閘極端子經由上拉電阻151、153連接於內側正極端子105故而為高位準，因此為斷開狀態。第2輸出電晶體162其源極端子為低位準、閘極端子經由下拉電阻152連接於內側負極端子106故而為低位準，因此為斷開狀態。第4輸出電晶體164其源極端子為低位準、閘極端子經由上拉電阻154連接於內側正極端子105故而為高位準，因此為接通狀態。檢測電晶體130其源極端子為高位準、閘極端子經由上拉電阻134連接於內側正極端子105故而為高位準，因此為斷開狀態。 When the power switch 114 is turned off, the source terminals of the first and third output transistors 161 and 163 are at a high level, and the gate terminals thereof are connected to the inner positive terminal 105 via the pull-up resistors 151 and 153. Therefore, it is a high level, so it is in a disconnected state. The second output transistor 162 has a source terminal of a low level, and the gate terminal is connected to the inner negative terminal 106 via the pull-down resistor 152, so that it is at a low level, and thus is in an off state. The fourth output transistor 164 has its source terminal at a low level, and the gate terminal is connected to the inner positive terminal 105 via the pull-up resistor 154, so that it is at a high level, and thus is in an on state. The detecting transistor 130 has a source terminal having a high level, and the gate terminal is connected to the inner positive terminal 105 via the pull-up resistor 134, so that it is at a high level, and thus is in an off state.

當電源開關114接通時，檢測電晶體130之閘極端子 經由第4輸出電晶體164連接於內側負極端子106故而自高位準切換為低位準，藉此檢測電晶體130接通。藉由檢測電晶體130接通，OR電路131之第2輸入端子變成高位準，自DCDC變換器121向RFIC122供給驅動電壓Vdd，RFIC122驅動，電池式電源裝置100之狀態自斷開狀態切換為可通訊狀態。 When the power switch 114 is turned on, the gate terminal of the transistor 130 is detected. The fourth output transistor 164 is connected to the inner negative terminal 106, thereby switching from the high level to the low level, thereby detecting that the transistor 130 is turned on. When the detecting transistor 130 is turned on, the second input terminal of the OR circuit 131 becomes a high level, and the driving voltage Vdd is supplied from the DCDC converter 121 to the RFIC 122, and the RFIC 122 is driven, and the state of the battery type power supply device 100 is switched from the off state to the state. Communication status.

第5實施形態之電池式電源裝置100係經由無線通訊部而自外部資訊處理裝置200接收與馬達轉動方向之切換指示相關之代碼無線信號。當接收到用於使馬達正轉之代碼無線信號時，依照控制部之控制而自OUTPUT1端子輸出由控制信號產生部產生之閘極控制信號。另一方面，當接收到用於使馬達逆轉之代碼無線信號時，依照控制部之控制而自OUTPUT2端子輸出由控制信號產生部產生之閘極控制信號。當閘極控制信號自OUTPUT1端子輸出時，第1、第4輸出電晶體161、164相互同時地接通/斷開。同樣地，當閘極控制信號自OUTPUT2端子輸出時，第2、第3輸出電晶體162、163相互同時地接通/斷開。另，以自OUTPUT1端子與OUTPUT2端子不同時輸出閘極控制信號之方式進行設定。藉此，當第1、第4輸出電晶體164接通時，第2、第3輸出電晶體163不接通，可避免電路之誤動作、電路短路等。 The battery-type power supply device 100 according to the fifth embodiment receives a code radio signal related to an instruction to switch the direction of rotation of the motor from the external information processing device 200 via the wireless communication unit. When the code wireless signal for forward rotation of the motor is received, the gate control signal generated by the control signal generating portion is output from the OUTPUT1 terminal in accordance with the control of the control unit. On the other hand, when the code wireless signal for reversing the motor is received, the gate control signal generated by the control signal generating portion is output from the OUTPUT2 terminal in accordance with the control of the control unit. When the gate control signal is output from the OUTPUT1 terminal, the first and fourth output transistors 161 and 164 are turned on/off at the same time. Similarly, when the gate control signal is output from the OUTPUT2 terminal, the second and third output transistors 162 and 163 are turned on/off at the same time. In addition, the gate control signal is output when the OUTPUT1 terminal is different from the OUTPUT2 terminal. Thereby, when the first and fourth output transistors 164 are turned on, the second and third output transistors 163 are not turned on, and malfunction of the circuit, short circuit of the circuit, and the like can be avoided.

如以上所說明般，於電源開關114斷開之狀態下，藉由將4個輸出電晶體161、162、163、164中之1個輸出電晶體、此處為第4輸出電晶體164設為接通狀態，當電 源開關114接通時，可將檢測電晶體130之閘極端子自高位準切換為低位準。即，將4個輸出電晶體161、162、163、164中之1個輸出電晶體設為接通狀態，而能夠進行電池式電源裝置100之電源開關114之接通/斷開之檢測。由於能夠檢測電源開關114之接通/斷開，故而即便於電池式電源裝置100具備用於使馬達115能夠正逆轉之H橋控制電路的情形時，如以上所說明般，亦可與電源開關114之接通/斷開連動地進行電池式電源裝置100之通訊功能之接通/斷開、通訊間隔之變更等。 As described above, in the state where the power switch 114 is turned off, one of the four output transistors 161, 162, 163, and 164 is outputted from the transistor, and here, the fourth output transistor 164 is set. On state, when electricity When the source switch 114 is turned on, the gate terminal of the detecting transistor 130 can be switched from a high level to a low level. In other words, one of the four output transistors 161, 162, 163, and 164 is turned on, and the power source switch 114 of the battery power source device 100 can be turned on/off. Since it is possible to detect the on/off of the power switch 114, even when the battery type power supply device 100 is provided with an H-bridge control circuit for enabling the motor 115 to be reversed, as described above, it is also possible to be connected to the power switch. The ON/OFF of the communication function of the battery type power supply device 100, the change of the communication interval, and the like are performed in conjunction with the ON/OFF of 114.

另，構成第1至第5實施形態之電池式電源裝置100之電路係由外部負載、外部電源及電源開關一併構成之電路。因此，藉由於具有外部負載、外部電源及電源開關之其它電子機器組入電池式電源裝置100之電路，此電子機器係與第1至第5實施形態之電池式電源裝置100同樣地動作，獲得同樣之效果。 Further, the circuits constituting the battery-type power supply device 100 according to the first to fifth embodiments are circuits including an external load, an external power supply, and a power supply switch. Therefore, the electronic device is operated in the same manner as the battery-type power supply device 100 according to the first to fifth embodiments, and the other electronic devices having the external load, the external power supply, and the power switch are incorporated in the circuit of the battery-type power supply device 100. The same effect.

此處，為了自馬達115產生之浪湧電壓保護輸出電晶體120，將保護用二極體171以相對於馬達115而與輸出電晶體120並列地自外側負極端子104朝外側正極端子103為順向之方式配置，為了防止或減少外部電池300之漏電流之產生，將曾納二極體172與保護用二極體171朝向相反地連接。但，用於防止或減少外部電池300之漏電流之產生之電路構成並不限定於此。 Here, in order to protect the output transistor 120 from the surge voltage generated by the motor 115, the protective diode 171 is slid from the outer negative terminal 104 toward the outer positive terminal 103 in parallel with the output transistor 120 with respect to the motor 115. In order to prevent or reduce the occurrence of leakage current of the external battery 300, the Zener diode 172 and the protective diode 171 are connected in opposite directions. However, the circuit configuration for preventing or reducing the occurrence of leakage current of the external battery 300 is not limited thereto.

圖15、圖16、圖17、圖18係表示第2實施形態之電池式電源裝置100之其它例之等效電路圖。參照圖 15、圖16、圖17、圖18，說明用於防止或減少外部電池300之漏電流之產生的其它電路構成。另，以第2實施形態為例進行說明，但用於防止或減少漏電流之產生之其它構成可應用於其它實施形態。 FIG. 15, FIG. 16, FIG. 17, and FIG. 18 are equivalent circuit diagrams showing another example of the battery-type power supply device 100 according to the second embodiment. Reference map 15. Fig. 16, Fig. 17, and Fig. 18 illustrate other circuit configurations for preventing or reducing the occurrence of leakage current of the external battery 300. Further, the second embodiment will be described as an example, but another configuration for preventing or reducing the occurrence of leakage current can be applied to other embodiments.

如圖15所示，為了自馬達115產生之浪湧電壓保護輸出電晶體120，且防止或減少外部電池300之漏電流之產生，保護用電晶體173係相對於馬達115而與輸出電晶體120並列地配置。此處，保護用電晶體173為N通道MOSFET，其汲極端子連接於外側正極端子103，閘極端子連接於RFIC122之OUTPUT2端子，源極端子連接於外側負極端子104。又，當OUTPUT2端子開放時，為了以低位準穩定保護用電晶體173之閘極端子，保護用電晶體173之閘極端子經由下拉電阻176而連接於GND。保護用電晶體173係依照來自RFIC122之控制信號，而控制其接通/斷開。具體而言，保護用電晶體173係依照RFIC122之控制，於輸出電晶體120自接通即將切換為斷開前接通。又，保護用電晶體173係依照RFIC122之控制，自接通起經過馬達115產生之浪湧電壓變小之一定時間後斷開。即，至少於馬達115產生浪湧電壓之期間，保護用電晶體173為接通狀態。因此，伴隨輸出電晶體120之接通/斷開，即便馬達115產生浪湧電壓(逆起電壓)，浪湧電流亦會被包含保護用電晶體173及馬達115之閉電路消耗，故而輸出電晶體120之汲極-源極間不會施加浪湧電壓帶來之高電壓。因此，可自馬達115產生之浪湧電壓保 護輸出電晶體120。 As shown in FIG. 15, in order to protect the output transistor 120 from the surge voltage generated by the motor 115, and to prevent or reduce the generation of leakage current of the external battery 300, the protection transistor 173 is coupled to the output transistor 120 with respect to the motor 115. Parallel configuration. Here, the protective transistor 173 is an N-channel MOSFET, the drain terminal is connected to the outer positive terminal 103, the gate terminal is connected to the OUTPUT2 terminal of the RFIC 122, and the source terminal is connected to the outer negative terminal 104. Further, when the OUTPUT2 terminal is opened, in order to stabilize the gate terminal of the protection transistor 173 at a low level, the gate terminal of the protection transistor 173 is connected to GND via the pull-down resistor 176. The protective transistor 173 is controlled to be turned on/off in accordance with a control signal from the RFIC 122. Specifically, the protection transistor 173 is turned on before the output transistor 120 is switched from on to off in accordance with the control of the RFIC 122. Further, the protective transistor 173 is turned off after a certain period of time during which the surge voltage generated by the motor 115 becomes small after being turned on in accordance with the control of the RFIC 122. That is, the protective transistor 173 is turned on at least during the period in which the motor 115 generates a surge voltage. Therefore, with the on/off of the output transistor 120, even if the motor 115 generates a surge voltage (reverse voltage), the inrush current is consumed by the closed circuit including the protection transistor 173 and the motor 115, so that the output is output. The high voltage caused by the surge voltage is not applied between the drain and the source of the crystal 120. Therefore, the surge voltage can be generated from the motor 115 The output transistor 120 is protected.

當保護用電晶體173為斷開狀態時，藉由保護用電晶體173而將包含內置電池、輸出電晶體120及保護用電晶體173之閉電路遮斷，可避免內置電池之短路。又，當保護用電晶體173為斷開狀態時，可藉由保護用電晶體173而將包含外部電池400、馬達115及保護用電晶體173之閉電路遮斷，由此可防止或減少外部電池300之漏電流。 When the protective transistor 173 is turned off, the closed circuit including the built-in battery, the output transistor 120, and the protective transistor 173 is blocked by the protective transistor 173, so that the short circuit of the built-in battery can be avoided. Further, when the protective transistor 173 is turned off, the closed circuit including the external battery 400, the motor 115, and the protective transistor 173 can be blocked by the protective transistor 173, whereby the external portion can be prevented or reduced. The leakage current of the battery 300.

保護用電晶體173係於輸出電晶體120即將斷開前接通，故而產生保護用電晶體173與輸出電晶體120均為接通狀態之期間。若無任何對策，則因自內側正極端子105經由輸出電晶體120、保護用電晶體173後連接內側負極端子106之電流路徑，而內置電池短路。此處，係以自外側負極端子104朝外側正極端子103為順向之方式，將短路避免用之二極體177串列連接於保護用電晶體173，藉此可避免當輸出電晶體120與保護用電晶體173均為接通狀態時之內部電池之短路。 The protective transistor 173 is turned on immediately before the output transistor 120 is turned off, so that the protective transistor 173 and the output transistor 120 are both turned on. If there is no countermeasure, the current path of the inner negative terminal 106 is connected to the inner positive electrode terminal 105 via the output transistor 120 and the protective transistor 173, and the built-in battery is short-circuited. Here, the short-circuit avoidance diode 177 is connected in series to the protective transistor 173 so that the short-circuit avoidance diode 177 is aligned from the outer negative terminal 104 toward the outer positive terminal 103, whereby the output transistor 120 can be avoided. The protective transistor 173 is short-circuited to the internal battery when it is in the ON state.

另，若保護用電晶體173之斷開/接通可與輸出電晶體120之接通/斷開同步，便可省略短路避免用之二極體177。又，可藉由利用電阻等代替短路避免用之二極體177而避免內置電池之短路。 Further, if the opening/closing of the protection transistor 173 can be synchronized with the on/off of the output transistor 120, the short-circuit avoidance diode 177 can be omitted. Further, the short circuit of the internal battery can be avoided by using a resistor or the like instead of the short-circuit avoiding diode 177.

如圖16所示，亦可僅將保護用二極體171相對於馬達115而與輸出電晶體120並列配置。藉由使用具有較輸出電晶體120之逆擊穿電壓低之順向電壓特性之保護用二極體171，可自馬達115產生之浪湧電壓保護輸出電晶體 120。又，藉由使用具有較外部電池300之合計電壓高之順向電壓特性之保護用二極體171，可防止或減少外部電池300之漏電流之產生。進而，藉由使用具有較外部電池300之合計電壓高、且較輸出電晶體120之逆擊穿電壓低之順向電壓特性的保護用二極體171，可兼具自馬達115產生之浪湧電壓保護輸出電晶體120之功能、及防止或減少外部電池300之漏電流之產生的功能。 As shown in FIG. 16, only the protective diode 171 may be arranged in parallel with the output transistor 120 with respect to the motor 115. The output transistor can be protected from the surge voltage generated by the motor 115 by using the protective diode 171 having a forward voltage characteristic lower than the reverse breakdown voltage of the output transistor 120. 120. Moreover, by using the protective diode 171 having a forward voltage characteristic higher than the total voltage of the external battery 300, generation of leakage current of the external battery 300 can be prevented or reduced. Further, by using the protective diode 171 having a higher total voltage than the external battery 300 and lowering the reverse breakdown voltage of the output transistor 120, the surge generated from the motor 115 can be used. The voltage protects the function of the output transistor 120 and the function of preventing or reducing the generation of leakage current of the external battery 300.

於輸出電晶體120自接通切換為斷開而馬達115產生浪湧電壓之情形時，保護用二極體171因浪湧電壓而導通。藉此，浪湧電流被包含保護用二極體171及馬達115之閉電路消耗，不會對輸出電晶體120施加高電壓。因此，可自馬達115產生之浪湧電壓保護輸出電晶體120。另一方面，當輸出電晶體120為穩定狀態時，於保護用二極體171僅施加有較低之逆向電壓，故而保護用二極體171為斷開狀態。藉此，包含保護用二極體171及馬達115之閉電路遮斷，可防止或減少外部電池300之漏電流之產生。又，包含保護用二極體171及輸出電晶體120之閉電路被遮斷，可避免內置電池之短路。 When the output transistor 120 is switched from on to off and the motor 115 generates a surge voltage, the protection diode 171 is turned on by the surge voltage. Thereby, the inrush current is consumed by the closed circuit including the protection diode 171 and the motor 115, and a high voltage is not applied to the output transistor 120. Therefore, the output transistor 120 can be protected by the surge voltage generated from the motor 115. On the other hand, when the output transistor 120 is in a stable state, only a low reverse voltage is applied to the protective diode 171, so that the protective diode 171 is in an off state. Thereby, the closed circuit including the protective diode 171 and the motor 115 is blocked, and the occurrence of leakage current of the external battery 300 can be prevented or reduced. Further, the closed circuit including the protective diode 171 and the output transistor 120 is blocked, and the short circuit of the built-in battery can be avoided.

如圖17所示，亦可為了自馬達115產生之浪湧電壓保護輸出電晶體120，將保護用二極體171以相對於馬達115而與輸出電晶體120並列地自外側負極端子104朝外側正極端子103為順向之方式配置，為了減少外部電池300產生之漏電流，將低減用電阻174連接於保護用二極體171。於該電路構成中，無關於輸出電晶體120之接通/ 斷開，包含保護用二極體171及馬達115之閉電路均為導通狀態。當馬達115產生浪湧電壓時，浪湧電流被該閉電路消耗，故而可自馬達115產生之浪湧電壓保護輸出電晶體120。另一方面，當輸出電晶體120為穩定狀態時，自外部電池300向閉電路流通漏電流。但，該閉電路介置有電阻值較高之電阻174，藉此可減小其漏電流，從而可減少外部電池300之消耗。 As shown in FIG. 17, the output transistor 120 can also be protected from the surge voltage generated from the motor 115, and the protective diode 171 is laterally outward from the outer negative terminal 104 in parallel with the output transistor 120 with respect to the motor 115. The positive electrode terminal 103 is disposed in a forward direction, and the low-reduction resistor 174 is connected to the protective diode 171 in order to reduce leakage current generated by the external battery 300. In this circuit configuration, regardless of the turn-on of the output transistor 120 / When it is disconnected, the closed circuit including the protective diode 171 and the motor 115 is in an on state. When the motor 115 generates a surge voltage, the inrush current is consumed by the closed circuit, so that the surge voltage can be generated from the motor 115 to protect the output transistor 120. On the other hand, when the output transistor 120 is in a steady state, a leakage current flows from the external battery 300 to the closed circuit. However, the closed circuit is provided with a resistor 174 having a relatively high resistance value, whereby the leakage current can be reduced, thereby reducing the consumption of the external battery 300.

如圖18所示，亦可為了自馬達115產生之浪湧電壓保護輸出電晶體120，將保護用二極體171以相對於馬達115而與輸出電晶體120並列地自外側負極端子104朝外側正極端子103為順向之方式配置，為了防止或減少外部電池300產生之漏電流，將電容器175連接於保護用二極體171。電容器175將電流之直流成分遮斷。外部電池300產生之漏電流為直流，故而包含保護用二極體171及馬達115之閉電路中不會流通外部電池300之漏電流。因此，藉由電容器175，可防止或減少當輸出電晶體120為穩定狀態時之外部電池300之漏電流之產生。當馬達115產生浪湧電壓時，藉由電容器175吸收並減少瞬間產生之浪湧電壓，由此可自浪湧電壓保護輸出電晶體120。 As shown in FIG. 18, the output transistor 120 can also be protected from the surge voltage generated from the motor 115, and the protective diode 171 is laterally outward from the outer negative terminal 104 in parallel with the output transistor 120 with respect to the motor 115. The positive electrode terminal 103 is disposed in a forward direction, and the capacitor 175 is connected to the protective diode 171 in order to prevent or reduce leakage current generated by the external battery 300. Capacitor 175 blocks the DC component of the current. Since the leakage current generated by the external battery 300 is DC, the leakage current of the external battery 300 does not flow in the closed circuit including the protection diode 171 and the motor 115. Therefore, by the capacitor 175, generation of leakage current of the external battery 300 when the output transistor 120 is in a stable state can be prevented or reduced. When the motor 115 generates a surge voltage, the instantaneous surge voltage is absorbed and reduced by the capacitor 175, whereby the output transistor 120 can be protected from the surge voltage.
