Abstract:
An electrostatic discharge protection circuit includes: a pulse detection unit, a delay unit, a control unit, and a discharge unit. The pulse detection unit is configured to detect an electrostatic pulse signal; the delay unit is configured to delay or enhance driving capability of the pulse detection signal output by the pulse detection unit; the control unit is configured to generate a control signal based on a first delay signal and a second delay signal output by the delay unit; and the discharge unit is configured to open or close an electrostatic charge discharge passage based on the control signal output by the control unit.
