ABSTRACT:
An electrostatic discharge protection circuit immune to latch-up during normal operation is disclosed. The ESD protection circuit is positioned at an IC pad for protecting an internal circuit within an integrated circuit from ESD damage. The electrostatic discharge protection circuit comprises a silicon-controlled rectifier and an ON/OFF controller. The silicon-controlled rectifier coupled between the IC pad and a grounding node to form an ESD path, wherein the ON/OFF controller is arranged in the conduction path. During normal operation the ON/OFF controller disconnects the ESD path so as to avoid latch-up even if noise interference happens.
