This application relates to a charging protection circuit. The charging protection circuit implements overcurrent protection by using a four-terminal NMOS switching transistor. In the solution provided in this application, floating management is performed on a Sub port of the four-terminal NMOS switching transistor. Specifically, when the four-terminal NMOS switching transistor is turned on, potential of the Sub port is pulled up, to avoid an excessively large internal resistance of the four-terminal NMOS switching transistor caused by an excessively large voltage between the Sub port and a drain of the four-terminal NMOS switching transistor. In addition, this application further provides a charging circuit and an electronic device.
