Abstract
An apparatus for protecting an integrated circuit from an electrostatic discharge (ESD) event includes a multiple stage triggering network configured between a pair of power rails, and a power clamp coupled to the multiple stage triggering network, the power clamp configured to discharge current from the ESD event. The multiple stage triggering network has a first control path and a second control path configured to individually control activation of the power clamp.
