Abstract
In a power-supply device, a FET passes or blocks a current flowing from one side in a power-supply circuit. A current sensor detects a current flowing into the FET. A FET is coupled to the FET, and passes or blocks a current flowing from another side in the power-supply circuit. A current sensor detects a current flowing into the FET. A junction couples a load unit at a point between the FET and the FET. In each of switch units, a CPU controls the corresponding switch unit of the power-supply circuit based on the detection result detected by the corresponding current sensors.
