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.

Integrated circuit and electrostatic discharge protection circuit thereof

An anti-floating circuit including a first pull-high circuit, a first pull-low circuit and a first control circuit is provided. The first pull-high circuit includes a first P-type transistor and a second P-type transistor and is coupled to a first power terminal. The first pull-low circuit includes a first N-type transistor and a second N-type transistor and is coupled to a second power terminal. A first path is between the first P-type transistor and the first N-type transistor. A second path is between the second P-type transistor and the second N-type transistor. A third path is between the first P-type transistor and the second power terminal. In the first mode, the control circuit turns on the first and second paths and turns off the third path. In the second mode, the control circuit turns off the first and second paths and turns on the third path.
