ESD protection circuit
摘要:
An ESD circuit is disclosed. The ESD circuit includes a pad and a ground and a sensing element coupled between the pad and ground for sensing an ESD current. The sensing element generates an active sense output signal when an ESD current is sensed and an inactive sense output signal when no ESD current is sensed. The ESD circuit also includes a bypass element comprising a bi-polar junction transistor. The bypass element is coupled in parallel to the sensing element between the pad and ground. The active sense output signal causes the bypass element to be activated to provide a current path between the pad and ground.
