摘要： Circuit and method for RC power clamp triggered dual SCR ESD protection. In an integrated circuit, a protected pad is coupled to an upper SCR circuit and a lower SCR circuit; and both are coupled to the RC power clamp circuit, which is coupled between the positive voltage supply and the ground voltage supply. A structure for ESD protection is disclosed having a first well of a first conductivity type adjacent to a second well of a second conductivity type, the boundary forming a p-n junction, and a pad contact diffusion region in each well electrically coupled to a pad terminal; additional diffusions are provided proximate to and electrically isolated from the pad contact diffusion regions, the diffusion regions and first and second wells form two SCR devices. These SCR devices are triggered, during an ESD event, by current injected into the respective wells by an RC power clamp circuit.

摘要： An ESD protection circuit includes a pad of an IC, circuitry coupled to the pad for buffering data, an RC power clamp on the IC, and first and second silicon controlled rectifier (SCR) circuits. The RC power clamp is coupled between a positive power supply terminal and a ground terminal. The first SCR circuit is coupled between the pad and the positive power supply terminal. The first SCR circuit has a first trigger input coupled to the RC power clamp circuit. The second SCR circuit is coupled between the pad and the ground terminal. The second SCR circuit has a second trigger input coupled to the RC power clamp circuit. At least one of the SCR circuits includes a gated diode configured to selectively provide a short or relatively conductive electrical path between the pad and one of the positive power supply terminal and the ground terminal.
