Patent ID: 8630073

Claim:
An integrated circuit protected against overvoltage conditions comprising: an output amplification stage having a first power transistor of a first type connected in series with a second power transistor of a second type between a first power rail and a second power rail; an output signal pad connected between the first power transistor and the second power transistor; a first resistor connected to a first gate of the first power transistor; a second resistor connected to a second gate of the second power transistor; a signal control circuit configured to provide a first signal through the first resistor to the first gate of the first power transistor and a second signal through the second resistor to the second gate of the second power transistor; and an overvoltage sensing circuit configured to provide a first control signal to a first node between the first resistor and the first gate and a second control signal to a second node between the second resistor and the second gate.
