Abstract

The invention discloses a charging and discharging circuit and electronic equipment, and belongs to the field of electronic circuits. The charging and discharging circuit comprises a charging interface, a power management IC, a buck-boost charge pump IC, a battery and an external low-voltage module; the first end of the power management IC is connected with the charging interface, the second end of the power management IC is connected with the first end of the buck-boost charge pump IC, and the third end of the power management IC is connected with the external low-voltage module; and the second end of the buck-boost charge pump IC is connected with the positive electrode of the battery. The charging and discharging circuit can solve the problems of large occupied board area and high cost.

Description

technical field [0001] The application belongs to the field of electronic circuits, and in particular relates to a charging and discharging circuit and an electronic device. Background technique [0002] At present, mobile phones using dual-cell batteries are more and more widely used. [0003] The charging and discharging circuit of a mobile phone with dual batteries can be as follows: figure 1 shown. Specifically, the charging and discharging circuit includes a Type-C interface, a buck-boost charging IC, a 2:1 step-down charge pump, a power management IC, a peripheral low-voltage module, and a dual-cell battery. [0004] However, if figure 1 The number of electronic components in the charging and discharging circuit shown is relatively large, which leads to a large board area occupied by the charging and discharging circuit and high cost. Contents of the invention [0005] The purpose of the embodiments of the present application is to provide a charging and discharg...
