Abstract:
Aspects of the invention provide an electrostatic discharge (ESD) protection device with reduced current leakage, and a related method. In one embodiment, an ESD protection device for an integrated circuit (IC) is provided. The ESD protection device includes: a resistor-capacitor (RC) timing circuit for selectively turning on the ESD protection device during an ESD event; a trigger circuit for receiving an output of the RC timing circuit and generating a trigger pulse for driving at least one of: a first ESD clamp and a second ESD clamp; and a selection circuit for selecting one of: the trigger circuit or a charge pump for controlling the second ESD clamp.
