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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Charging protection circuit, charging circuit, and electronic device","description":"This application relates to a charging protection circuit.
