Title:
SILICON CONTROLLED RECTIFIER ELECTROSTATIC DISCHARGE PROTECTION DEVICE
Document Type and Number:
WIPO Patent Application WO2004093133
Kind Code:
A3
Abstract:
An electrostatic discharge (ESD) protection device (1000), for protecting power lines (1050) of an integrated circuit. In one embodiment, the ESD protection device includes a first silicon controlled rectifier (SCR) (10021) coupled between a first power line (10501) and a second power line(10502), and a second SCR (10022), coupled anti-parallel to the first SCR between the first and second power lines. A first trigger device (10201) is coupled to the first power line and a first trigger gate (10081) of the first SCR, and a second trigger device (10202) coupled to the second power line and a first trigger gate (10082) 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.
