Abstract
The present disclosure provides an electrostatic discharge (ESD) protection circuit, coupled between a first reference terminal and a second reference terminal; the ESD protection circuit includes a first voltage divider, a second voltage divider, a first trigger circuit, a second trigger circuit, a first discharge component and a second discharge component. The first trigger circuit includes a first GaN based transistor, including a first source/drain and a second source/drain coupled to the first reference terminal and a gate coupled to the second reference terminal via the first voltage divider. The second trigger circuit includes a terminal coupled to the first reference terminal via the second voltage divider. The first discharge component includes a gate coupled between the first trigger circuit and the first voltage divider. The second discharge component includes a gate coupled between the second trigger circuit and the second voltage divider.
