Abstract
An ESD circuit includes an ESD clamp device with an ESD clamp transistor. The ESD clamp transistor has two sets of one or more body contacts. One set is coupled to a supply voltage rail and the other set is coupled to a clamp activation circuit. The clamp activation circuit is coupled to a clamp device. During an electrical stress event of a sufficient severity affecting a supply voltage rail, the activation circuit makes the clamp device conductive to transfer charge between supply voltage rails.
