Abstract
A power supply control device controls a supply of power by switching a FET on or off. A current that rises when a current flowing through the FET rises flows through a resistor circuit. A drive circuit makes a notification when a voltage across both ends of the resistor circuit reaches a voltage greater than or equal to a reference voltage. A microcomputer instructs an application circuit to apply a voltage to the resistor circuit. As a result, the application circuit applies a voltage greater than or equal to the reference voltage to the resistor circuit. After instructing the application circuit to stop applying the voltage to the resistor circuit, the microcomputer determines whether or not the drive circuit is making the notification.
