Abstract

The invention relates to the technical field of electrons, and provides a charging circuit. The charging circuit comprises a charging control circuit and at least two charging integrated circuits (ICs), wherein the at least two charging ICs are connected with each other in parallel; a common output end of the charging ICs is connected with a charging input end of a battery; and the charging control circuit is used for controlling the at least two charging ICs to charge the battery. The invention further provides a mobile terminal. According to the charging circuit and the mobile terminal provided by the invention, the cost can be effectively controlled when heavy current charging is achieved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a charging circuit and a mobile terminal. Background technique [0002] As the capacity of the battery of the existing mobile terminal is getting larger and larger, the charging time of the battery is also getting longer and longer. In order to shorten the charging time of the mobile terminal, a charging IC (Integrated Circuit) supporting a large current is usually used to charge the battery For charging, however, the high-current charging IC process requirements are relatively high, making it expensive and increasing the production cost of mobile terminal manufacturers. [0003] At the same time, since the existing mobile terminal charges the battery through a single-chip charging IC, the current flowing through the charging IC is large, which easily causes the problem of high heat generation during charging, which makes the surface temperature of the mobile terminal relativ...
