Abstract: A current flows between the drains of FETs, which function as a switch. A first constant current circuit causes a constant current to flow from the FET side of a resistor to the other side thereof. A first comparator outputs a high level voltage to the control section if the electric potential at the drain of the FET is higher than the electric potential at one end, on the first constant current circuit side, of the resistor. Furthermore, the first comparator outputs a low level voltage to the control section if the electric potential at the drain of the FET is lower than the electric potential at one end, on the first constant current circuit side, of the resistor. The control section turns the FETs off when the first comparator outputs the low level voltage. Furthermore, the control section changes the current that is caused to flow through the resistor by the first constant current circuit.
