Abstract:
The present invention provides an ESD protection circuit electrically connected between a high voltage power line and a low voltage power line, and the ESD protection circuit includes a bipolar junction transistor (BJT) and a trigger source. A collector of the BJT is electrically connected to the high voltage power line, and an emitter and a base of the BJT are electrically connected to the low voltage power line. The trigger source is electrically connected between the base of the BJT and the high voltage power line.
