Abstract
An ESD protection circuit includes at least a first and a second silicon controlled rectifier (SCR) circuits. The first SCR circuit is coupled between the pad and the positive power supply terminal. The second SCR circuit is coupled between the pad and the ground terminal. At least one of the SCR circuits is 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.
