WIPO Patent Application WO/2019/061120
Kind Code:
A1
Abstract:
Disclosed are a surge protection circuit and a surge protection device. The surge protection circuit comprises a feedback module, a switch module, a control module and a surge protection module, wherein one end of the feedback module is connected to a first end of the switch module; the other end of the feedback module is connected to one end of the control module; the other end of the control module is connected to a second end of the switch module; and a third end of the switch module is connected to the surge protection module. By means of the present invention, when there is an excessively high surge voltage, an excessively high surge voltage and/or surge current can be prevented from being transmitted to the surge protection module so as to protect a chip and/or a circuit of the surge protection module.
