ABSTRACT:
An electrostatic discharge (ESD) protection circuit for the protection of an electronic circuit from an ESD event. The electronic circuit, in operation, is provided with a supply voltage and a reference voltage (typically electrical ground) via voltage terminals and/or power supply buses. The protection circuit includes two bipolar transistors in series, where the transistors are coupled between the supply voltage terminal/bus and the reference voltage terminal/bus. The bases of the transistors are coupled via a connection including two resistors in series, where the connection point between the two resistors is coupled with the connection point between the two transistors.
