Abstract
An apparatus includes a transistor coupled between an input pin and an output pin and an overvoltage detection circuit configured to receive a serial interface signal from the input pin and generate an enable signal in response to a voltage of the serial interface signal exceeding a voltage threshold. The apparatus also includes a first circuit configured to apply a clamping voltage to a gate of the transistor based on the enable signal to regulate a voltage provided at the output pin.
