Abstract
An electrostatic discharge protection circuit is provided. The electrostatic discharge protection circuit includes an electrostatic discharge detection circuit, a discharge circuit, and a switch. The electrostatic discharge detection circuit detects whether an electrostatic discharge event occurs at the bounding pad to generate a first detection circuit. The discharge circuit receives the first detection signal. When the electrostatic discharge event occurs at the bounding pad, the discharge circuit provides a discharge path between the bounding pad and a ground terminal according to the first detection signal. The switch is coupled between the core circuit and the ground terminal and controlled by the first detection signal. When the electrostatic discharge event occurs at the bounding pad, the switch is turned off according to the first detection signal.
