Abstract
A system includes a clamp network coupled between an input and an output and configured to clamp a voltage between the input and the output to a first clamp voltage based on the presence of a trigger signal and to a second clamp voltage based on the absence of the trigger signal. The second clamp voltage is greater than the first clamp voltage and the first clamp voltage is less than a breakdown voltage of the power transistor device. A detector circuit is coupled to the input and the output. A power transistor device may also be coupled between the input and the output. The detector circuit is configured to detect a pulse signal at the input or the output while the power transistor device is off and to generate the trigger signal for a time interval based on detecting the pulse signal.
