Abstract
A circuit and method for electrostatic discharge (ESD) protection. The ESD protection circuit includes: a silicon control rectifier (SCR) connected between a first voltage rail and a second voltage rail; one or more diodes connected in series in a forward conduction direction between the first voltage rail and a source of a p-channel field effect transistor (PFET); a drain of the PFET connected to the SCR and connected to ground through a current trigger device; and a control circuit connected to the gate of the PFET.
