Embodiments of the present disclosure provide a cell protection circuit and an electronic device. The circuit includes a control module, multistage cell units coupled in series and N output interfaces. A positive electrode of a first-stage cell unit and a negative electrode of a last-stage cell unit are each coupled to an output interface, and a negative electrode of each upper-stage cell unit and a positive electrode of an adjacent lower-level cell unit are coupled to a same output interface. A protection module is coupled between at least one output interface in the N output interfaces and a cell unit coupled thereto. The control module is coupled to the protection module, and is configured to control the protection module to be turned off when an electrical signal on a path where the protection module is located is abnormal. N is an integer greater than or equal to 3. The technical solution according to the embodiments of the present disclosure can implement three or more output interfaces in a cell protection circuit, and realize charging and discharging protection of the cell based on the output interfaces.
