Abstract
In an embodiment a circuit provides protection against electrostatic discharge (ESD). A shunt device is controlled to provide a current bypass upon the occurrence of an ESD event. A trigger circuit controls operation of the shunt device and includes an inverter and a hysteresis means to prevent oscillation of the trigger circuit. A reference is used to trigger the control circuit and has a time constant associated with it to distinguish between power up events and ESD events.
