Abstract
A voltage-dividing circuit, which is formed of serially connected voltage-dividing resistors R, R, R, is disposed between the source terminal S of a power MOSFETand the ground. The divided voltage Va at a connecting point A is applied to one of the input terminals of a comparator, while the divided voltage Vb at a connecting point B is applied to one of the input terminals of a comparator. The other input terminals of the comparatorsare connected to the connecting line between an external terminal P, to which an external resistoris connected, and an FET
