POWER SUPPLY CONTROL DEVICE AND POWER SUPPLY CONTROL METHOD

An ECU controls the supply of power to a load. An upstream switch and a downstream switch are respectively arranged upstream and downstream of the load in a current path of the flow of current through the load. A control unit of a microcomputer determines whether or not current is flowing through th...

Zusammenfassung:	An ECU controls the supply of power to a load. An upstream switch and a downstream switch are respectively arranged upstream and downstream of the load in a current path of the flow of current through the load. A control unit of a microcomputer determines whether or not current is flowing through the upstream switch while an instruction to switch OFF the upstream switch has been given. If it was determined that current is flowing through the upstream switch, the control unit gives an instruction to switch OFF the downstream switch.
