Abstract:
An electrostatic discharge (ESD)-triggered protection apparatus includes a first circuit and a second circuit. The first circuit includes an ESD trigger circuit to sense an ESD pulse and to generate a switching pulse responsive to the ESD pulse; a first ESD discharge device communicatively coupled to the ESD trigger circuit and responsive to the switching pulse to transfer a current generated by the ESD pulse to the ground rail; a control circuit that generates a control signal in response to the switching pulse. The second circuit includes at least one trigger cell buffer that is configured to receive the control signal and to control a second ESD discharge device such that the current generated by the ESD pulse is transferred to the ground rail.
