ABSTRACT:
An electrostatic discharge (ESD) protection circuit in a semiconductor integrated circuit (IC) having protected circuitry is provided herein. In one embodiment, a circuit for protecting an integrated circuit from ESD includes a protected circuit node in the integrated circuit, a multiple stage transistor pump circuit coupled to the protected circuit node, and an electrostatic discharge protection circuit having a trigger coupled to the multiple stage transistor pump circuit. The multiple stage transistor pump circuit may comprise a Darlington transistor pump circuit.
