Abstract
A system and method are provided for electrostatic discharge (ESD) protection circuit having overshoot and undershoot voltage protection during a power supply ramp-up of the circuit. In a specific embodiment, the ESD protection circuit of the present invention includes an ESD discharge circuit coupled between a power supply node and a ground supply node, a trigger circuit coupled to the ESD discharge circuit, the trigger circuit to turn the ESD discharge circuit on in the presence of a voltage spike during the power supply ramp-up and to turn the ESD discharge circuit off in the absence of a voltage spike during the power supply ramp-up, and a delay circuit coupled between the discharge circuit and the trigger circuit, the delay circuit to slow down the turn-off of the discharge circuit to prevent an overshoot or undershoot voltage condition during the power supply ramp-up of the circuit.
