Classification: CPC G  H | IPC H

Claim 15:
16. The semiconductor device according to claim 11, wherein
the first reference voltage and the second reference voltage are input to the gate of the first switch transistor and the gate of the second switch transistor, respectively,
the disconnection detection circuit sets the first reference voltage to one of the first and second power supply voltages that corresponds to a gate voltage to turn on the first switch transistor at a time of non-occurrence of the first disconnection and sets the first reference voltage to a voltage equivalent to a voltage at the output terminal at a time of occurrence of the first disconnection, and
the disconnection detection circuit sets the second reference voltage to the other of the first and second power supply voltages that corresponds to a gate voltage to turn on the second switch transistor at a time of non-occurrence of the second disconnection and sets the second reference voltage to a voltage equivalent to a voltage at the output terminal at a time of occurrence of the second disconnection.
