摘要：
A voltage-dividing circuit 60, which is formed of serially connected voltage-dividing resistors R1, R2, R3, is disposed between the source terminal S of a power MOSFET 15 and the ground. The divided voltage Va at a connecting point A is applied to one of the input terminals of a comparator 62, while the divided voltage Vb at a connecting point B is applied to one of the input terminals of a comparator 64. The other input terminals of the comparators 62, 64 are connected to the connecting line between an external terminal P4, to which an external resistor 12 is connected, and an FET 30.
