Abstract
In a second detection circuit, a current output device outputs, to a circuit resistor, a current corresponding to a circuit voltage between an input terminal of a second FET to which a current is input and ground of a second drive circuit that switches the second FET ON or OFF. The second detection circuit outputs a voltage between two ends of the circuit resistor. A voltage between the ground of the second drive circuit and a downstream end of the circuit resistor is higher than 0 V.
