In a power supply control device (10), power supply is controlled by switching an FET (20) on or off. When the current flowing through the FET (20) has increased, the increased current flows through the resistance circuit (25). The drive circuit (23) notifies that the voltage between the two ends of the resistance circuit (25) is equal to or greater than the reference voltage. The microcomputer (27) instructs the application circuit (26) to apply a voltage to the resistance circuit (25). As a result, the application circuit (26) applies a voltage equal to or greater than the reference voltage to the resistance circuit (25). The microcomputer (27) determines whether or not the drive circuit (23) performs notification after the instruction application circuit (26) applies the voltage to the resistance circuit (25).

    在供电控制装置(10)中,通过将FET(20)切换成导通或断开来控制供电。在经由FET(20)流过的电流上升了的情况下上升的电流经由电阻电路(25)流过。驱动电路(23)在电阻电路(25)的两端之间的电压为基准电压以上的电压的情况下进行告知。微型机(27)指示施加电路(26)向电阻电路(25)施加电压。由此,施加电路(26)将基准电压以上的电压施加于电阻电路(25)。微型机(27)在指示施加电路(26)向电阻电路(25)施加电压之后,判定驱动电路(23)是否进行告知。
