Abstract
An electronic circuit includes a failure detection circuit that detects an abnormality of the gate potential of a transistor of a bridge circuit. The failure detection circuit monitors an output voltage of a drive circuit that is to be the gate potential of the transistor of the bridge circuit and, when detecting an abnormality, stops the drive circuit.
