Abstract
Systems and methods for protecting a device from an electrostatic discharge (ESD) event are provided. A resistor-capacitor (RC) trigger circuit and a driver circuit are provided. The RC trigger circuit is configured to provide an ESD protection signal to the driver circuit. A discharge circuit includes a first metal oxide semiconductor (MOS) transistor and a second MOS transistor connected in series between a first voltage potential and a second voltage potential. The driver circuit provides one or more signals for turning the first and second MOS transistors on and off.
