Abstract:
An electrostatic discharge protection system with a node adapted to receive a signal and threshold detecting circuitry coupled to the node. The system includes an IGBT having an IGBT gate coupled to an output of the threshold detecting circuitry, a resistor coupled between an IGBT emitter of the IGBT and a low reference potential node, and a BJT having a BJT base coupled to the IGBT emitter.
