Abstract: In a power feeding control device, a control unit determines whether or not a current is flowing through at least one of the first switches, when an instruction to turn off first switches has been given. If it is determined that a current is flowing, the control unit causes a first capacitor to discharge via a current path of the current flowing through a second switch.

Abstract: A load drive circuit includes a power source terminal (“PST”), a power source and a load terminal connecting a load to the power source. A semiconductor switch connects the PST to the load terminal. A control circuit includes an output terminal for opening/closing the semiconductor switch. A freewheeling circuit includes a freewheeling diode and a protection switch blocks a current from the power source to the semiconductor switch when the power source is connected in a reverse manner. A first terminal connects the control circuit to a first fixed potential and a second terminal connects an anode of the freewheeling diode to a second fixed potential. A connection circuit includes a connection switch connecting the output terminal and the first terminal. The connection circuit connects the output terminal to the first terminal when a rise in a potential difference between the first terminal and the second terminal is detected.
