Abstract: A device for providing electrostatic discharge (ESD) protection includes circuitry configured to detect an occurrence of an ESD event at one or more voltage rails. An ESD clamp is activated via a clamp triggering path to provide a discharge path for an ESD current. A gate voltage of the ESD clamp is maintained greater than a predetermined threshold via a holding path in parallel with the clamp triggering path.
