ABSTRACT:
A protection circuit includes a diode chip, and a switching device integrated with the diode chip, the switching device being isolated, optically triggered, optically powered, and the diode chip connected between a high side terminal of the switching device and an input to a first inverting amplifier, the diode chip further supplying a current when an overvoltage occurs between a drain and a source of the switching device.
