Abstract
An electric power is surely supplied to a load even if an abnormality is generated in a switching control circuit, which controls a switching part that switches electric connection between a power supply and the load of a vehicle. The switching control circuit controls a state of a contact of a keep relay that switches the electric connection between the power supply and the load. A monitor circuit monitors existence or non-existence of the abnormality of the switching control circuit. When detecting the abnormality of the switching control circuit, the monitor circuit transmits a reset signal in order to reset a state of the switching control circuit. When receiving the reset signal from the monitor circuit, an abnormal-time connection circuit transmits a connection signal to a coil of the keep relay to bring a movable contact into contact with a contact. For example, the present invention can be applied to a power-supply control device for the vehicle.
