The present disclosure provides an electrostatic protection circuit and a
semiconductor chip. The electrostatic protection circuit is connected between a first
voltage terminal and a second
voltage terminal, and includes a detection circuit connected between the first
voltage terminal and the second voltage terminal, for generating a transient
control signal in response to an electrostatic pulse between the first voltage terminal and the second voltage terminal; a
delay circuit connected to an output terminal of the detection circuit, for delaying or enhancing a driving capability of the transient
control signal and outputting a
delay signal; a
discharge circuit connected between the first voltage terminal and the second voltage terminal; a
control circuit connected to an output terminal of the
delay circuit and a control terminal of the
discharge circuit, for controlling the
discharge circuit to discharge electrostatic according to the delay
signal; and a reset circuit connected to the control terminal of the discharge circuit and the output terminal of the detection circuit, for resetting the potential of the control terminal of the discharge circuit according to the potential of the output terminal of the detection circuit after the
electrostatic discharge ends.
