COMBINED ESD ACTIVE CLAMP FOR CASCADED VOLTAGE PINS

摘要

A combined electro static discharge clamp for cascaded voltage pins can include an electronic switch, a plurality of discharge paths, and a plurality of trigger circuits. In response to detecting a voltage event across any two voltage pins, the trigger circuitry can turn on the 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.
