Abstract

A power supply control device controls power supply to a load through a power supply switch. A driving circuit switches on or off the power supply switch. When the driving circuit switches the power supply switch from off to on, a waveform value regarding the current waveform of a current that flows through the load is output by a waveform value detection unit to a microcomputer. The microcomputer determines power supply control conditions regarding control of power supply to the load based on the waveform value that is input from the waveform detection unit.
