Central combined active ESD clamp

Central combined active ESD clamp

An electrostatic discharge clamp for groups of terminals having cascaded and different voltage classes, a plurality of discharge paths, and a multiple-input trigger circuit. In response to detecting a positive voltage event at any of the groups of terminals, the trigger circuitry can turn on an elec...

Zusammenfassung:An electrostatic discharge clamp for groups of terminals having cascaded and different voltage classes, a plurality of discharge paths, and a multiple-input trigger circuit. In response to detecting a positive voltage event at any of the groups of terminals, the trigger circuitry can turn on an electronic switch causing current caused by the voltage event to flow through one or more of the discharge paths instead of through functional circuitry which could potentially be damaged by the current caused by the voltage event.
