In one embodiment the present invention includes a circuit comprising an amplifier, a first monitor circuit, a second monitor circuit, a third monitor circuit, and a control circuit. The amplifier comprises a first transistor and a second transistor driven by first and second signals, respectively. The amplifier stage provides an amplifier output signal through the output terminal of the amplifier stage. The first monitor circuit generates an output signal indicating a condition of the first signal. The second monitor circuit generates an output signal indicating a condition of the second signal. The third monitor circuit generates an output signal indicating a condition of the amplifier output signal. If a short circuit condition is indicated by the monitor circuits, the control circuit generates a shut down.
