Abstract
An apparatus for protecting an integrated circuit from electrostatic discharge (ESD) includes an RC trigger device configured between a pair of power rails, a first control path coupled to the RC trigger device, and a second control path coupled to the RC trigger device. A power clamp is configured between the power rails for discharging current from an ESD event, the power clamp having an input coupled to outputs of the first and second control paths, the power clamp independently controllable by the first and second control paths. The first and second control paths are further configured to prevent the power clamp from reactivating following an initial deactivation of the power clamp.
