SHORT-CIRCUIT DETERMINATION CIRCUIT

A short-circuit determination circuit includes a current detection unit, a voltage detection unit, and a short-circuit determination unit. The current detection unit detects the current flowing in a power circuit. The voltage detection unit detects the voltage applied to the power circuit. The short-circuit determination unit determines a short circuit in the power circuit on the basis of the difference between a detection value of the current detected by the current detection unit and a detection value of the voltage detected by the voltage detection unit.
