Abstract
An inrush current higher than a second anomaly threshold current ILfc passes through a power MOSFET, when a control signal Sof low level is applied to a gate driverso that the power MOSFETand the like turn to a conductive state. A first forcing shutoff operation for the power MOSFETis then prevented, because a first anomaly threshold current ILoc is set to an initial level higher than the inrush current. A fuse time counterstarts a count-up operation in response to the occurrence of the inrush current, and continues to increment its count value until a load current IL falls below the second anomaly threshold current ILfc. According to the count value, the first anomaly threshold current ILoc is decreased stepwise with time.
