Abstract

In a power supply control device, a switching device turns a main switch on or off to control supply of power via the main switch. When a battery supplies power to the switching device, a fuse is disposed in a first current path of an output current output from the switching device. A diode is disposed in a second current path of the output current different from the first current path. If a current flowing through the fuse increases to or above a first threshold, the fuse blows. If a current flowing through the diode increases to or above a second threshold, the diode blows.
