Abstract
An electrostatic discharge (ESD) protection circuit including a detection circuit for detecting an ESD current and a bypass circuit for bypassing the ESD circuit is provided. The detection circuit and the bypass circuit are connected between a first pad and a second pad. The bypass circuit includes a transistor, a diode and a resistor. The drain of the transistor is connected to the first pad. The source of the transistor is connected to the second pad and the anode of the diode. The substrate terminal of the transistor is connected to the cathode of the diode and an output of the detection circuit. The transistor is connected between the substrate terminal and the second pad. The diode may be adopted for maintaining the voltage at the substrate terminal to be steady for turning on the transistor.
