Claim 2:
3. The semiconductor device according to claim 2, wherein
the output transistor control circuit includes two sub-transistors of a same conductivity type connected in series between the output voltage node and the gate of the first or second output transistor,
the two sub-transistors have back gate terminals connected in common to a connection node of the two sub-transistors,
the output signal from the disconnection detection circuit is input to the gates of the two sub-transistors,
the output signal input to the two sub-transistors connected to the first output transistor is set to a voltage at the output terminal at a time of non-occurrence of the first disconnection and set to the second power supply voltage at a time of occurrence of the first disconnection, and
the output signal input to the two sub-transistors connected to the second output transistor is set to a voltage at the output terminal at a time of non-occurrence of the second disconnection and set to the first power supply voltage at a time of occurrence of the second disconnection.
