摘要： An overvoltage protection circuit includes a connection jack, a path connection module, a voltage response module, and a control module. The connection jack is connected to a power supply. The path connection module is connected between the connection jack and a load. The voltage response module is to output a first signal in response to an overvoltage, and output a second signal in response to a constant voltage. The control module is to output a corresponding potential according to the first signal to turn off the path connection module, and output a corresponding potential according to the second signal to turn on the path connection module. When the path connection module is turned off, the connection between the connection jack and the load is disabled, when the path connection module is turned on, the connection between the connection jack and the load is enabled.
