Abstract
A power-supply control device includes a power-source input terminal, an output circuit outputting power to load, power interrupting circuits connected in parallel between the power-source input terminal and the output circuit, and a control circuit controlling each power interrupting circuit separately. Each power interrupting circuit includes an interrupting circuit and a switch element connected in series between the power-source input terminal and the output circuit. The interrupting circuit permits power to pass when receiving a passage permitting signal from the control circuit and interrupts passage of power when not receiving the passage permitting signal. ON/OFF of the switch element is controlled by the control circuit. When any of the power interrupting circuits is set as a diagnostic target circuit, the control circuit stops supplying the passage permitting signal to the interrupting circuit of the diagnostic target circuit and turns off the switch element of the diagnostic target circuit.
