Description
本發明是關於一種電源供應器用之一控制治具裝置,更特別地,本發明是關於一種用於設定一電源供應器的一保護晶片之一過電流保護態樣之控制治具裝置及方法。 BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a control fixture apparatus for a power supply, and more particularly to a control fixture apparatus and method for setting an overcurrent protection aspect of a protection wafer of a power supply.
傳統的過電流保護架構是由硬體電路設計,完全是由保護晶片及其週邊電路設計而成。零件的誤差以及電路佈局設計的誤差往往造成同一批生產出來的產品的OCP(Over Current Protection,過電流保護,以下簡稱OCP)的保護電流範圍非常不集中,甚至與預期設定相差甚遠,除了考量保護晶片本身的誤差外並且需要使用高精密度的零件(RL,RS,Ri等電阻)做匹配,因此增加零件成本;即使使用可變電阻(VR),也需要由人工於生產流程中進行調整,但仍無法避免人工手調的誤差。 The traditional overcurrent protection architecture is designed by a hardware circuit and is designed entirely from the protection chip and its peripheral circuits. The error of the parts and the error of the circuit layout design often cause the OCP (Over Current Protection, OCP) protection current range of the same batch of products to be very inconsistent, even far from the expected setting, except for the protection. The error of the chip itself and the need to use high-precision parts (resistances such as RL, RS, Ri) to match, thus increasing the cost of parts; even if a variable resistor (VR) is used, it needs to be adjusted manually by the production process. However, it is still impossible to avoid the error of manual adjustment.
雖然新一代的保護晶片本身具備可接收設定訊號的功能,控制治具可以送出啟動OCP調整的訊號,當保護晶片接受到訊號後,保護晶片會讓電源供應器(Power Supply Unit,以下簡稱PSU)開機並且進行OCP設定。所有的傳輸方式皆為單線單向,是由ATE(Automatic Test Equipment,自動測試設備,以下簡稱ATE)設定好負載後再送出觸發訊號(TTL)給控制治 具;控制治具根據該觸發訊號來送出特定固定的訊號到保護晶片的輸入腳(如PSON)。 Although the new generation of protection chip itself has the function of receiving the setting signal, the control fixture can send the signal for starting the OCP adjustment. When the protection chip receives the signal, the protection chip will make the power supply unit (Power Supply Unit, PSU for short). Power on and perform OCP settings. All transmission methods are single-line one-way. After the load is set by ATE (Automatic Test Equipment, ATE), the trigger signal (TTL) is sent to the control. The control fixture sends a specific fixed signal to the input pin (such as PSON) of the protection chip according to the trigger signal.
但是,由於控制治具只用來觸發保護晶片進行設定OCP保護的訊號,在設定期間控制治具無法讀取保護晶片及PSU的狀態,且保護晶片設定完成後控制治具也無法確認寫入結果。因此一旦保護晶片在設定OCP保護的過程中有錯誤發生,控制治具當然也無法確認異常緣由,從而無法立即排除。 However, since the control jig is only used to trigger the protection chip to set the OCP protection signal, the control jig cannot read the state of the protection chip and the PSU during the setting period, and the control jig cannot confirm the writing result after the protection chip setting is completed. . Therefore, once the protection wafer has an error in the process of setting the OCP protection, the control fixture can of course not confirm the cause of the abnormality, and thus cannot be immediately eliminated.
請參照第1圖,第1圖係顯示具有一傳統單線單向控制介面的一控制系統1a,該控制系統1a包含一自動化測試設備100、一控制治具101、一電源供應器102及一負載103,其中該電源供應器102包含一保護晶片102.1。該自動化測試設備100與該控制治具101、該電源供應器102及該負載103電連接,該自動化測試設備100可自動化地測試該電源供應器102之開、關機等功能。 Please refer to FIG. 1. FIG. 1 shows a control system 1a having a conventional single-wire one-way control interface. The control system 1a includes an automatic test equipment 100, a control fixture 101, a power supply 102, and a load. 103, wherein the power supply 102 includes a protection wafer 102.1. The automated test equipment 100 is electrically coupled to the control fixture 101, the power supply 102, and the load 103. The automated test equipment 100 can automatically test the power supply 102 for opening, shutting down, and the like.
在該自動化測試設備100設定完成該負載103之負載狀態後,該自動化測試設備100發送觸發訊號(TTL)至該控制治具101,此時該自動化測試設備100對該電源供應器102斷開控制;再由該控制治具101送出特定訊號至該保護晶片102.1。由於該自動化測試設備100不知道整個設定流程是否結束,因此該自動化測試設備100等待一特定時間(例如10秒)後,確定該整個設定流程結束後再重新控制該電源供應器102。由於該整個流程皆為單線單向,因此該自動化測試設備100也無從得知該設定流程是否結束。 After the automated test equipment 100 sets the load state of the load 103, the automated test equipment 100 sends a trigger signal (TTL) to the control fixture 101, at which time the automated test equipment 100 turns off the power supply 102. Then, the control jig 101 sends a specific signal to the protection chip 102.1. Since the automated test equipment 100 does not know whether the entire set process is finished, the automated test equipment 100 waits for a certain time (for example, 10 seconds) to determine that the power supply 102 is re-controlled after the entire set flow is completed. Since the entire process is a single-line one-way, the automated test equipment 100 also has no way of knowing whether the setting process is over.
在具有公告號I367612的台灣發明專利中,揭露了一種過電流保護電路及應用其之電源轉換器。該電源轉換器雖包含一迴授控制電 路,但該迴授控制電路並不具雙向傳輸的功能。 In the Taiwan invention patent having the publication number I367612, an overcurrent protection circuit and a power converter using the same are disclosed. The power converter includes a feedback control Road, but the feedback control circuit does not have the function of two-way transmission.
在具有公開號201417433的台灣發明專利申請中,揭露了一種電源供應器之過電流保護晶片及其設定方法。該專利雖揭露一過電流保護晶片,但該專利主要是利用接收一負載電流偵測訊號、一基準訊號、一單元設定資料及一比較訊號等,來進行過電流保護設定,該過電流保護晶片並未具有雙向傳輸的功能。 In the Taiwan invention patent application with the publication No. 201417433, an overcurrent protection wafer of a power supply and a setting method thereof are disclosed. Although the patent discloses an overcurrent protection chip, the patent mainly uses an input current detection signal, a reference signal, a unit setting data, and a comparison signal to perform an overcurrent protection setting. It does not have the function of two-way transmission.
具有該傳統單線單向控制介面的該控制系統1a如上所述。由於目前的保護晶片不具有迴授功能,因此控制治具送出特定脈波後,後續的控制皆由保護晶片自己辨識,如此發生異常或產生誤差都無法即時偵測。 The control system 1a having the conventional single-line one-way control interface is as described above. Since the current protection chip does not have a feedback function, after the control jig sends a specific pulse wave, the subsequent control is recognized by the protection chip itself, and such an abnormality or an error cannot be detected immediately.

請參照第2圖,第2圖係顯示本發明之第一例示性實施例之具有一雙線單向控制介面的一控制系統2a。在第2圖中,該控制系統2a包含一自動化測試設備200、一控制治具裝置201、一電源供應器202、一第一傳輸線T1、一第二傳輸線T2及一負載203。該電源供應器202包含一保護晶片202.1,該控制治具裝置201包含一控制單元201.1。在第2圖中,該自動化測 試設備200耦接於該控制治具裝置201、該電源供應器202及該負載203,而該電源供應器202耦接於該負載203。該控制單元201.1經由該第一傳輸線T1及該第二傳輸線T2與該保護晶片202.1電連接。 Referring to FIG. 2, a second diagram showing a control system 2a having a two-wire one-way control interface according to a first exemplary embodiment of the present invention. In FIG. 2, the control system 2a includes an automated test equipment 200, a control fixture device 201, a power supply 202, a first transmission line T1, a second transmission line T2, and a load 203. The power supply 202 includes a protective wafer 202.1, and the control fixture device 201 includes a control unit 201.1. In Figure 2, the automated test The test device 200 is coupled to the control fixture device 201, the power supply 202, and the load 203, and the power supply 202 is coupled to the load 203. The control unit 201.1 is electrically connected to the protection wafer 202.1 via the first transmission line T1 and the second transmission line T2.
本發明之該控制治具裝置201具備自動化之啟動方式。控制系統2a的自動化架構包含多個連接器(線材),該多個連接器(線材)將可編程的該自動化測試設備200連接到該控制治具裝置201、該負載203和該電源供應器202,以便該自動化測試設備200進行控制。該自動化測試設備200可以送出觸發訊號K1(TTL訊號)啟動該控制治具裝置201,送出設定訊號H1以自動化設定該負載203以模擬該電源供應器202所需之負載值,並且可以針對該電源供應器202進行電源系統的全功能驗證(例如像是開機、關機以及效能等),以達到全自動化測試流程。 The control jig device 201 of the present invention is provided with an automated starting method. The automation architecture of the control system 2a includes a plurality of connectors (wires) that connect the programmable automated test equipment 200 to the control fixture device 201, the load 203, and the power supply 202 In order for the automated test equipment 200 to control. The automatic test equipment 200 can send the trigger signal K1 (TTL signal) to activate the control fixture device 201, send the setting signal H1 to automatically set the load 203 to simulate the load value required by the power supply 202, and can be used for the power source. The provider 202 performs full-feature verification of the power system (such as booting, shutdown, and performance, etc.) to achieve a fully automated testing process.
該自動化測試設備200亦可送出觸發信號K1以啟動該控制治具裝置201。該控制治具裝置201只在當要設定該保護晶片202.1時才會被啟動,當該自動化測試設備200送出觸發信號K1以啟動該控制治具裝置201時,該自動化測試設備200同時斷開對該電源供應器202控制的動作。 The automated test equipment 200 can also send a trigger signal K1 to activate the control fixture device 201. The control fixture device 201 is only activated when the protection wafer 202.1 is to be set. When the automatic test equipment 200 sends the trigger signal K1 to activate the control fixture device 201, the automatic test equipment 200 is simultaneously disconnected. The action controlled by the power supply 202.
請再回到第2圖,當該控制治具裝置201接收到該自動化測試設備200送出之觸發信號K1時,即進入第一情況,此時該控制單元201.1會經由該第一傳輸線T1傳輸一第一訊號S1至該保護晶片202.1。由於該負載203為直接耦接於該電源供應器202,因此只有該電源供應器202之該保護晶片202.1能偵測到該負載203被設定的數值。透過傳輸該第一訊號S1至該保護晶片202.1以探詢該第一訊號S1是否與該負載203的數值相吻合。 Please return to FIG. 2, when the control fixture device 201 receives the trigger signal K1 sent by the automated test equipment 200, the first situation is entered, at which time the control unit 201.1 transmits a first transmission line T1. The first signal S1 to the protection wafer 202.1. Since the load 203 is directly coupled to the power supply 202, only the protection chip 202.1 of the power supply 202 can detect the value set by the load 203. The first signal S1 is transmitted to the protection chip 202.1 to inquire whether the first signal S1 matches the value of the load 203.
於第二情況時,該保護晶片202.1在接收該第一訊號S1後, 該保護晶片202.1會經由該第二傳輸線T2,迴授一第二訊號S2至該控制單元201.1。例如當該負載203被設定為具有15A的負載電流,則該控制單元201.1透過傳輸該第一訊號S1(例如,代表10A的負載電流),至該保護晶片202.1,因10A與15A並不吻合,該保護晶片202.1經由該第二傳輸線T2,迴授該第二訊號S2告知該第一訊號S1所代表的值不合。在該控制單元201.1收到該第二訊號S2後,會再送出代表11A之該第一訊號S1再次探詢。經由不斷的嘗試與錯誤來達到類似於傳統可變電阻調整之效果。 In the second case, after the protection chip 202.1 receives the first signal S1, The protection chip 202.1 sends a second signal S2 to the control unit 201.1 via the second transmission line T2. For example, when the load 203 is set to have a load current of 15A, the control unit 201.1 transmits the first signal S1 (for example, a load current representing 10A) to the protection wafer 202.1, because 10A and 15A do not match. The protection chip 202.1 sends back the second signal S2 via the second transmission line T2 to notify the value represented by the first signal S1. After the second signal S2 is received by the control unit 201.1, the first signal S1 of the representative 11A is sent again to interrogate. Achieving effects similar to conventional variable resistance adjustments through constant trials and errors.
第一例示性實施例之控制系統2a的應用原理為利用該保護晶片202.1原有的PSON接腳來作為該第一傳輸線T1的連接端,再利用PGO(Power Good)接腳來作為該第二傳輸線T2的連接端,以增加迴授訊號。 The application principle of the control system 2a of the first exemplary embodiment is to use the original PSON pin of the protection chip 202.1 as the connection end of the first transmission line T1, and then use the PGO (Power Good) pin as the second. The connection end of the transmission line T2 to increase the feedback signal.

如第3(a)圖所示,該自動化測試設備300耦接於該控制治具 裝置301、該電源供應器302及該負載303,而該電源供應器302耦接於該負載303。該控制單元301.1經由該傳輸線Tx與該保護晶片302.1電連接。具有該單線雙向控制介面的控制系統3a-1與具有該雙線單向控制介面的控制系統2a之主要區別技術特徵為,該控制單元301.1只經由一條傳輸線Tx與該保護晶片302.1電連接。由於部份的保護晶片並不具有PGO接腳,因此採取訊號共用的方式。本發明之控制系統3a-1可應用於只有PSON接腳之保護晶片。 As shown in FIG. 3( a ), the automated test equipment 300 is coupled to the control fixture The device 301, the power supply 302 and the load 303, and the power supply 302 is coupled to the load 303. The control unit 301.1 is electrically connected to the protection wafer 302.1 via the transmission line Tx. The main distinguishing feature of the control system 3a-1 having the single-wire bidirectional control interface and the control system 2a having the two-wire unidirectional control interface is that the control unit 301.1 is electrically connected to the protection wafer 302.1 via only one transmission line Tx. Since some of the protection chips do not have PGO pins, signal sharing is adopted. The control system 3a-1 of the present invention can be applied to a protection wafer having only PSON pins.
在本發明之一實施例中,該控制單元301.1為微處理器。該控制單元301.1可經由送出指令至該保護晶片302.1以詢問該保護晶片302.1是否具有PGO接腳,再根據來自該保護晶片302.1的回傳訊號來決定要採用單線雙向介面或雙線單向介面。 In an embodiment of the invention, the control unit 301.1 is a microprocessor.

請參照第3(b)圖,第3(b)圖係顯示執行多單元自動辨識功能之程序3a-2之第一例示性實施例流程圖。請額外參照第3(a)圖。該控制治具裝置301根據接收自該保護晶片302.1之迴授訊號可進行多單元自動辨識功能以進行一過電流保護設定P。該程序3a-2是敘述如下。在步驟310中,該控制單元301.1經由該傳輸線Tx傳輸一第一訊號S1至該保護晶片302.1以詢問要對哪個設定單元(該第一設定單元G1、該第二設定單元G2及該第三設定單元G3的其中之一)進行過電流保護設定。在步驟311中,該保護晶片302.1自為判斷並確認一過電流保護設定目標單元Gp(如第3(b)圖所示即該第一設定單元G1)。 Please refer to FIG. 3(b), which shows a flow chart of the first exemplary embodiment of the program 3a-2 for performing the multi-cell automatic identification function. Please refer to Figure 3(a) for additional reference. The control fixture device 301 can perform a multi-cell automatic identification function based on the feedback signal received from the protection chip 302.1 to perform an overcurrent protection setting P. This procedure 3a-2 is described below. In step 310, the control unit 301.1 transmits a first signal S1 to the protection chip 302.1 via the transmission line Tx to inquire which setting unit to be used (the first setting unit G1, the second setting unit G2 and the third setting) One of the units G3) performs an overcurrent protection setting. In step 311, the protection wafer 302.1 determines and confirms an overcurrent protection setting target unit Gp (as shown in FIG. 3(b), the first setting unit G1).
接著,在步驟312中,該保護晶片302.1經由該傳輸線Tx迴授代表該過電流保護設定目標單元Gp的一第二訊號S2至該控制單元301.1。在步驟313中,該控制單元301.1經由該傳輸線Tx對該過電流保護設定目標單元 Gp進行該過電流保護設定P。在步驟314中,該控制單元301.1完成對該保護晶片302.1之該過電流保護設定P。 Next, in step 312, the protection chip 302.1 returns a second signal S2 representing the overcurrent protection setting target unit Gp to the control unit 301.1 via the transmission line Tx. In step 313, the control unit 301.1 sets the target unit for the overcurrent protection via the transmission line Tx. Gp performs this overcurrent protection setting P. In step 314, the control unit 301.1 completes the overcurrent protection setting P for the protection wafer 302.1.
該電源供應器302具備分別供應多個輸出電流給多個負載的能力,例如輸出電流至硬碟、中央處理器及顯示卡的其中至少一個。該保護晶片302.1能夠針對該多個輸出電流進行各自的過電流保護設定。當使用者決定好要對哪個設定單元(該被決定好的設定單元即之後會被該保護晶片302.1指定為過電流保護設定目標單元Gp)進行該過電流保護設定P後,即於該自動化測試設備300進行設定。以該第一設定單元G1代表負責供應輸出電流至硬碟、該第二設定單元G2代表負責供應輸出電流至中央處理器及該第三設定單元G3代表負責供應輸出電流至顯示卡為例(該負載303內部分別會有三個與該第一設定單元G1、該第二設定單元G2及該第三設定單元G3相對應的模擬單元),如使用者決定對該第一設定單元G1進行過電流保護設定,又該硬碟需要18A的電流,則該自動化測試設備300即會對該負載303進行模擬成該硬碟(不會對中央處理器及顯示卡進行模擬,一次一組)。 The power supply 302 has the capability of supplying a plurality of output currents to a plurality of loads, for example, output current to at least one of a hard disk, a central processing unit, and a display card. The protection wafer 302.1 is capable of performing respective overcurrent protection settings for the plurality of output currents. After the user decides which setting unit (the determined setting unit is to be designated as the overcurrent protection setting target unit Gp by the protection chip 302.1), the overcurrent protection setting P is performed, and the automatic test is performed. The device 300 performs setting. Taking the first setting unit G1 for supplying the output current to the hard disk, the second setting unit G2 for supplying the output current to the central processing unit, and the third setting unit G3 for supplying the output current to the display card as an example (the There are three analog units corresponding to the first setting unit G1, the second setting unit G2 and the third setting unit G3 respectively in the load 303, and the user decides to protect the first setting unit G1 from overcurrent. If the hard disk requires a current of 18 A, the automated test device 300 will simulate the load 303 into the hard disk (the CPU and the display card will not be simulated, one at a time).
此時該自動化測試設備300即會將該第一設定單元G1相對應的模擬單元設定為需要18A電流的負載,對其他兩個模擬單元設定為需要1A電流的負載。該負載303即會對該第一設定單元G1抽載18A電流,此時該保護晶片302.1能明顯辨識出此時該對該第一設定單元G1進行過電流保護設定(18A電流代表高電壓訊號,1A電流代表低電壓訊號)。首先,該控制治具裝置301使用具有迴授功能之該傳輸線Tx送出該第一訊號S1到該保護晶片302.1;然後,該保護晶片302.1迴授該第二訊號S2到該控制單元301.1以確認該保護晶片302.1的該過電流保護設定目標單元Gp(即於本例為該第一設 定單元G1);然後,該控制單元301.1針對該過電流保護設定單元Gp進行該過電流保護設定P。 At this time, the automatic test equipment 300 sets the analog unit corresponding to the first setting unit G1 to a load requiring 18A current, and sets the other two analog units to a load requiring 1A current. The load 303 will draw 18A current to the first setting unit G1. At this time, the protection chip 302.1 can clearly recognize that the first setting unit G1 is overcurrent protection setting (the 18A current represents a high voltage signal, 1A current represents a low voltage signal). First, the control fixture device 301 sends the first signal S1 to the protection chip 302.1 using the transmission line Tx having a feedback function; then, the protection chip 302.1 returns the second signal S2 to the control unit 301.1 to confirm the The overcurrent protection setting target unit Gp of the protection chip 302.1 (ie, the first design in this example) The unit G1); then, the control unit 301.1 performs the overcurrent protection setting P for the overcurrent protection setting unit Gp.
請參照第3(c)圖,第3(c)圖係顯示執行多單元自動辨識功能之程序3a-3之第二例示性實施例流程圖。請額外參照第3(a)圖。該保護晶片302.1更可延伸至包含該第一設定單元G1至一第N設定單元Gn。該程序3a-3是敘述如下。在步驟310中,該控制單元301.1經由該傳輸線Tx傳輸該第一訊號S1至該保護晶片302.1以詢問要對哪個設定單元(或過電流保護設定目標單元Gp)(該第一設定單元G1至該第N設定單元Gn其中之一)進行過電流保護設定。在步驟311中,該保護晶片302.1自為判斷及確認該過電流保護設定目標單元Gp。 Referring to FIG. 3(c), FIG. 3(c) is a flow chart showing a second exemplary embodiment of the program 3a-3 for performing the multi-cell automatic identification function. Please refer to Figure 3(a) for additional reference. The protection wafer 302.1 can further extend to include the first setting unit G1 to an Nth setting unit Gn. This procedure 3a-3 is described below. In step 310, the control unit 301.1 transmits the first signal S1 to the protection chip 302.1 via the transmission line Tx to inquire which setting unit (or overcurrent protection setting target unit Gp) is to be applied (the first setting unit G1 to the One of the Nth setting units Gn performs an overcurrent protection setting. In step 311, the protection wafer 302.1 sets the target unit Gp for determining and confirming the overcurrent protection.
接著,在步驟312中,該保護晶片302.1經由該傳輸線迴授代表該過電流保護設定目標單元Gp的該第二訊號S2至該控制單元301.1。在步驟313中,該控制單元301.1經由該傳輸線Tx對該過電流保護設定目標單元Gp進行該過電流保護設定P。在步驟314中,該控制單元301.1完成對該保護晶片302.1之該過電流保護設定P。 Next, in step 312, the protection chip 302.1 returns the second signal S2 representing the overcurrent protection setting target unit Gp to the control unit 301.1 via the transmission line. In step 313, the control unit 301.1 performs the overcurrent protection setting P on the overcurrent protection setting target unit Gp via the transmission line Tx. In step 314, the control unit 301.1 completes the overcurrent protection setting P for the protection wafer 302.1.
該程序3a-2與該程序3a-3之主要區別技術特徵是該保護晶片302.1可延伸到包含該第1設定單元G1至該第N設定單元Gn。 The main distinguishing feature of the program 3a-2 and the program 3a-3 is that the protection wafer 302.1 can be extended to include the first setting unit G1 to the Nth setting unit Gn.
請參照第3(d)圖,第3(d)圖係顯示執行多次重工之程序3a-4之第一例示性實施例流程圖。該控制治具裝置301根據接收自該保護晶片302.1之迴授訊號可進行多次重工功能。該程序3a-4是敘述如下。在步驟320中,該控制單元301.1經由該傳輸線Tx傳輸一第三訊號S3至該保護晶片302.1以了解該第一設定單元G1內之該第一設定單元之第一記憶體G11的儲存狀 況。在步驟321中,該保護晶片302.1根據該第一設定單元之第一記憶體G11的該儲存狀況來迴授代表該第一設定單元之第一記憶體G11的該儲存狀況的一第四訊號S4至該控制單元301.1;當該第一設定單元之第一記憶體G11之資料是在過電流保護未設定狀態中時(為空時),即表示無進行過該過電流保護設定P,則進入步驟322。在步驟322中,該控制單元301.1對該第一設定單元之第一記憶體G11進行初次之一第一過電流保護態樣A1的寫入。其中該第一過電流保護態樣A1代表例如像是保護點為18A的電流。 Please refer to FIG. 3(d), which shows a flow chart of the first exemplary embodiment of the procedure 3a-4 for performing multiple rework. The control fixture device 301 can perform multiple rework functions based on the feedback signal received from the protection chip 302.1. This procedure 3a-4 is described below. In step 320, the control unit 301.1 transmits a third signal S3 to the protection chip 302.1 via the transmission line Tx to learn the storage state of the first memory G11 of the first setting unit in the first setting unit G1. condition. In step 321 , the protection chip 302.1 reclaims a fourth signal S4 representing the storage condition of the first memory G11 of the first setting unit according to the storage condition of the first memory G11 of the first setting unit. To the control unit 301.1; when the data of the first memory G11 of the first setting unit is in the overcurrent protection unset state (when it is empty), that is, the overcurrent protection setting P has not been performed, then enter Step 322. In step 322, the control unit 301.1 performs writing of the first one of the first overcurrent protection patterns A1 on the first memory G11 of the first setting unit. Wherein the first overcurrent protection aspect A1 represents, for example, a current having a protection point of 18A.
當該第一設定單元之第一記憶體G11是在過電流保護已設定狀態中時(為有資料時),則進入步驟323。在步驟323中,該保護晶片302.1根據該第一設定單元之第二記憶體G12的儲存狀況來迴授代表該第一設定單元之第二記憶體G12的儲存狀況的一第四訊號S4至該控制單元301.1;當該第一設定單元之第二記憶體G12是在過電流保護未設定狀態中時(資料為空時),則回到步驟322;在步驟322中,該控制單元301.1對該第一設定單元之第二記憶體G12進行一第二過電流保護態樣A2的寫入,此即二次重工,其中該第二過電流保護態樣A2代表例如像是保護點為16A的電流。 When the first memory G11 of the first setting unit is in the overcurrent protection set state (when there is data), the process proceeds to step 323. In step 323, the protection chip 302.1 returns a fourth signal S4 representing the storage condition of the second memory G12 of the first setting unit according to the storage condition of the second memory G12 of the first setting unit. Control unit 301.1; when the second memory G12 of the first setting unit is in the overcurrent protection unset state (when the data is empty), return to step 322; in step 322, the control unit 301.1 The second memory G12 of the first setting unit performs writing of a second overcurrent protection pattern A2, that is, secondary rework, wherein the second overcurrent protection pattern A2 represents, for example, a current with a protection point of 16A. .
請參照第3(e)圖,第3(e)圖係顯示執行多次重工之程序3a-5之第二例示性實施例流程圖。該程序3a-5與該程序3a-4之區別技術特徵為步驟324。該第一設定單元G1可包含該第一設定單元之第一記憶體G11至一第一設定單元之第N記憶體G1n,該第二設定單元G2以及該第三設定單元G3亦可包含至第N記憶體。因此該控制治具裝置301本身亦同時具備多次重工的功能。針對特定設定單元,該控制治具裝置301需要知道哪一次要寫入哪一設定單元,因此需具備辨識第幾次進行該過電流保護設定P(重工)的功能。 Referring to Figure 3(e), Figure 3(e) is a flow chart showing a second exemplary embodiment of the procedure 3a-5 for performing multiple rework. The distinguishing feature of the program 3a-5 from the program 3a-4 is step 324. The first setting unit G1 may include the first memory G11 of the first setting unit to the Nth memory G1n of the first setting unit, and the second setting unit G2 and the third setting unit G3 may also be included N memory. Therefore, the control fixture device 301 itself also has the function of multiple rework. For the specific setting unit, the control fixture device 301 needs to know which setting unit is to be written, and therefore needs to recognize the function of performing the overcurrent protection setting P (rework) a few times.
由於當拿到該保護晶片302.1時不知道該保護晶片302.1進行過幾次該過電流保護設定P,該控制治具裝置301要能傳送指令至該保護晶片302.1才能夠知道該保護晶片302.1的該特定設定單元寫過幾次,假如已寫過了一次,那即進行第二次的寫入(即二次重工)。以該第一設定單元G1為例,該控制治具裝置301會針對該第一設定單元G1來依序送出不同的指令到該保護晶片302.1(即步驟320);該保護晶片302.1首先會根據該第一設定單元之第一記憶體G11的儲存狀況,將代表該第一設定單元之第一記憶體G11的儲存狀況的資料經迴授該第二訊號S2而傳回該控制治具裝置301(即步驟321)。當該控制治具裝置301接收到該保護晶片302.1的該第二訊號S2時,可以依照該第二訊號S2自動判定需進行寫入的重工順序(即步驟322)。 Since the protection chip 302.1 is not known to have performed the overcurrent protection setting P several times when the protection wafer 302.1 is obtained, the control fixture device 301 can transmit the command to the protection wafer 302.1 to know the protection wafer 302.1. The specific setting unit is written several times. If it has been written once, then the second write (ie, secondary rework) is performed. Taking the first setting unit G1 as an example, the control fixture device 301 sequentially sends different instructions to the protection chip 302.1 for the first setting unit G1 (ie, step 320); the protection chip 302.1 first depends on the The storage condition of the first memory G11 of the first setting unit returns the data representing the storage status of the first memory G11 of the first setting unit to the control fixture device 301 by returning the second signal S2 ( That is, step 321). When the control fixture device 301 receives the second signal S2 of the protection chip 302.1, the rework sequence to be written can be automatically determined according to the second signal S2 (ie, step 322).
當該第一設定單元之第一記憶體G11是在過電流保護已設定狀態中時(為有資料時),則進行步驟323;當該第一設定單元之第二記憶體G12是在過電流保護已設定狀態中時(為有資料時),則進行第三次重工,以此方式進行,可以直到進入步驟324;及對該第一設定單元之第N記憶體G1n進行一第N過電流保護態樣An的寫入。 When the first memory G11 of the first setting unit is in the overcurrent protection set state (when there is data), proceed to step 323; when the second memory G12 of the first setting unit is in an overcurrent When the protection state is set (when there is data), the third rework is performed in this manner, and may proceed to step 324; and an Nth overcurrent is performed on the Nth memory G1n of the first setting unit. Write the protection pattern An.
