Abstract
An electrostatic discharge circuit includes a discharge switch, a first trigger circuit and a second trigger circuit. A first terminal of the discharge switch is coupled to a first power domain, and a second terminal of the discharge switch is coupled to a second power domain. The first trigger circuit is coupled between the first terminal and a control terminal of the discharge switch. The second trigger circuit is coupled between the second terminal and the control terminal. When an electrostatic discharge voltage occurs in the first power domain, the second trigger circuit is configured to form a conduction voltage between the second terminal and the control terminal to turn on the discharge switch. When the electrostatic discharge voltage occurs in the second power domain, the second trigger circuit is configured to short the second terminal and the control terminal to turn on the discharge switch.
