Charging control circuit

The utility model provides a charging control circuit. The charging control circuit comprises a switch control module and a switching module. The switch control module comprises a driving chip U4, and the driving chip U4 comprises an input pin A, an input pin B, an output pin OA and an output pin OB; the switching module comprises a capacitor C1, a capacitor C5, a first switch unit and a second switch unit. According to the charging control circuit of the utility model, the switch control module is arranged to send the pulse control signal, and the switching module is arranged to realize the opening and closing of the two groups of switch units according to the pulse control signal, so that the two groups of capacitors can be switched between series connection and parallel connection, and flexible switching between two charging modes can be realized. In addition, controllable switching of charging modes can be realized by arranging two groups of modules, so that the circuit structure has the advantages of low
