Abstract: 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.

Abstract: This application discloses an image deployment method, where the image deployment method is applied to a container system. Information about an image that has been deployed on each host is collected. After an image tag of a to-be-deployed image is obtained, a degree of overlapping between the image that has been deployed on each host and the to-be-deployed image is determined. A host with a higher overlapping degree needs to download a smaller amount of data when deploying the to-be-deployed image and deploys the to-be-deployed image at a higher speed. Finally, a management node selects, according to overlapping degrees of the hosts, a deployment host for deploying the to-be-deployed image.
