ABSTRACT:
An electrostatic discharge (ESD) protection circuit for dissipating an ESD current from a first pad to a second pad during an ESD event. The ESD protection circuit includes a first bipolar transistor having an emitter coupled to the first pad. A second bipolar transistor having a base and a collector coupled to the second pad is used. Zero or more bipolar transistors are sequentially coupled between the first and second bipolar transistors in a base-to-emitter manner. A collector of the first bipolar transistor and the sequentially coupled transistors is connected to a base of a subsequently coupled bipolar transistor for helping to turn on the first, second and sequentially coupled bipolar transistors to provide a current path from the first pad to the second pad during an ESD event.
