Abstract
An electrostatic protection circuit includes: a monitoring unit, a discharge unit, and a controllable voltage dividing unit, where the monitoring unit is connected to at least one probe pad, a discharge unit and a controllable voltage dividing unit, and the monitoring unit is configured to generate a first trigger signal in response to that an electrostatic pulse is present on any probe pad; the discharge unit connected between the at least one probe pad and the ground pad, and configured to form, under control of the first trigger signal, at least one path for discharging electrostatic charges to the ground pad; and the controllable voltage dividing unit is connected to the discharge unit and is configured to share a part of voltage of the first trigger signal for the discharge unit.
