Wherein, the state of charge includes at least the magnitude of the charging current.

參閱圖3所示,微控制器150的具體控制邏輯如下。Referring to FIG. 3, the specific control logic of the microcontroller 150 is as follows.

當電力輸入端口110連接於外部電力源,例如電源適配器或電腦主機的連接端口時,微控制器150偵測電力輸入腳位Vcc的電壓大小,判斷電力輸入腳位Vcc的電壓大小是否超過門檻值,若超過則微控制器150通過控制端子156發出控制訊號,將開關元件130切換為切斷,使得電力輸入腳位Vcc與電力輸出腳位142之間為斷路而停止充電。When the power input port 110 is connected to an external power source, such as a power adapter or a connection port of the computer host, the microcontroller 150 detects the voltage level of the power input pin Vcc, and determines whether the voltage of the power input pin Vcc exceeds the threshold value. If it is exceeded, the microcontroller 150 sends a control signal through the control terminal 156 to switch the switching element 130 to be off, so that the power input pin Vcc and the power output pin 142 are disconnected to stop charging.

當電力輸出腳位142連接於待充電設備時,微控制器150以指示端子157,158偵測電力輸入腳位Vcc的電壓大小以及通過取樣電阻120的充電電流大小,若電壓或電流大於門檻值,微控制器150通過控制端子156發出控制訊號,將開關元件130切換為切斷,使得電力輸入腳位Vcc與電力輸出腳位142之間為斷路而停止充電。When the power output pin 142 is connected to the device to be charged, the microcontroller 150 detects the voltage of the power input pin Vcc and the magnitude of the charging current through the sampling resistor 120 by indicating the terminals 157, 158. If the voltage or current is greater than the threshold value, The controller 150 sends a control signal through the control terminal 156 to switch the switching element 130 to off, so that the power input pin Vcc and the power output pin 142 are disconnected to stop charging.

前述電壓及電流都正常時,微控制器150通過控制端子156發出控制訊號,將開關元件130切換為導通,使得電力輸入腳位Vcc與電力輸出腳位142之間為導通而進行充電。When the voltage and current are normal, the microcontroller 150 sends a control signal through the control terminal 156 to switch the switching element 130 to be conductive, so that the power input pin Vcc and the power output pin 142 are electrically connected.

此時,微控制器150偵測電流大小,並且通過指示端子157,158,依據充電狀態輸出指示訊號,使得狀態指示燈號160以燈號的明暗呈現充電狀態,例如電流大小。At this time, the microcontroller 150 detects the magnitude of the current, and outputs an indication signal according to the charging state through the indication terminals 157, 158, so that the status indicator number 160 exhibits a charging state, such as a current magnitude, in light and dark of the light.

以下舉一燈號的明暗呈現充電狀態的範例,但不以此為限:The following is an example of the state of charge of a light, but not limited to:

每3-5秒一個循環One cycle every 3-5 seconds

當通過取樣電阻120的充電電流大小下降到一個下限值後,就可以視為沒有電流流動,而完成待充電設備的充電,微控制器150通過控制端子156發出控制訊號,將開關元件130切換為切斷,使得電力輸入腳位 Vcc與電力輸出腳位142之間為斷路而停止充電。When the magnitude of the charging current through the sampling resistor 120 drops to a lower limit value, it can be regarded that no current flows, and charging of the device to be charged is completed, and the microcontroller 150 sends a control signal through the control terminal 156 to switch the switching element 130. To cut off, make the power input pin The charging is stopped between Vcc and the power output pin 142.
