ABSTRACT:
An electrostatic discharge (ESD) protection device, for protecting power lines of an integrated circuit. In one embodiment, the ESD protection device includes a first silicon controlled rectifier (SCR) coupled between a first power line and a second power line, and a second SCR coupled anti-parallel to the first SCR between the first and second power lines. A first trigger device is coupled to the first power line and a first trigger gate of the first SCR, and a second trigger device coupled to the second power line and a first trigger gate of the second SCR. The trigger devices and the SCRs provide power-down-mode-compatible operation of the power lines, as well as ESD protection.
