Abstract:
An output circuit has: a first driver circuit configured to receive a voltage of an input terminal and output a first voltage to an output terminal; a first comparison circuit configured to compare a first reference voltage with a voltage of the output terminal; a second driver circuit configured to receive the voltage of the input terminal and output a second voltage to the output terminal and become an off state according to a comparison result of the first comparison circuit; a second comparison circuit configured to compare a second reference voltage different from the first reference voltage with the voltage of the output terminal; and a third driver circuit configured to receive the voltage of the input terminal and output a third voltage to the output terminal and become an off state according to a comparison result of the second comparison circuit.
