Abstract
A second forcing shutoff operation is performed for a power MOSFETand the like, if a time when a load current (or a sense current Is) passing on a power supply line L exceeds a first threshold current Ia reaches a first reference time. On the other hand, the count value of a fuse time counteris cleared to be 'zero' so that the shutoff operation for the power MOSFETand the like is not performed, if a normal state, in which neither an overcurrent nor a fuse current has occurred, continues for a second reference time without the first reference time being reached.
