  • Power supply control device
    Patent number: 11870427
    Abstract: A power supply control device controls power supply by switching on or off a first semiconductor switch and a second semiconductor switch that are arranged on a current path. A first diode and a second diode are connected between a drain and a source of the first semiconductor switch and the second semiconductor switch, respectively. Cathodes of the first diode and the second diode are arranged downstream and upstream of the respective anode on the current path. If current flows through the current path even though a microcomputer has given an instruction to switch the first semiconductor switch and the second semiconductor switch off, a first drive circuit switches the first semiconductor switch on.
