Abstract

A driving circuit controlling a voltage level of an input/output pad and having an electrostatic discharge (ESD) protection function comprises a detector, a controller, and a release control element. The detector is configured to couple to a power terminal and the input/output pad. The controller is coupled to the detector. The release control element is coupled to the power terminal or the input/output pad and coupled to the controller. When an ESD event occurs at the power terminal or the input/output pad, the detector activates the controller to a control signal to control the voltage level of the input/output pad.
