Abstract:
A circuit for electrostatic discharge (ESD) protection is disclosed. The circuit includes multiple transistors that are selectively turned on during an ESD event. An ESD sense circuit detects an ESD event and asserts signals to activate an ESD protection circuit which closes multiple protection transistors to dissipate current during the ESD event. During normal operation of the circuit, the signals are de-asserted, disabling the ESD protection circuit.
