Abstract

An overvoltage protection circuit is provided. The overvoltage protection circuit includes a main transistor, a first resistance circuit and a second resistance circuit. The first resistance circuit is a circuit having a first resistance, and the second resistance circuit is a circuit having a second t resistance. A first terminal of the main transistor is coupled to an input voltage and connected to a first terminal of the first resistance circuit. A second terminal of the main transistor is used as an output terminal of the overvoltage protection circuit. A first terminal of the second resistance circuit is connected to a second terminal of the first resistance circuit. A control node between the first terminal of the second resistance circuit and the second terminal of the first resistance circuit is connected to a control terminal of the main transistor.
