Abstract

The invention discloses a charger charging circuit, a mobile terminal charging circuit, a charger and a mobile terminal. The charger charging circuit comprises a voltage conversion circuit which converts AC to DC for connecting to an AC charging power supply, a first charging interface, and a first control circuit. The first charging interface is used for connecting to a first charging interface of a mobile terminal; the first charging interface comprises a voltage output terminal connected to a voltage conversion circuit and a plurality of first data transmission terminals; one end of the first control circuit is connected to the voltage conversion circuit, and the other end of the first control circuit is connected to at least one first data transmission terminal among the first data transmission terminals. During fast charging, the first control circuit controls connection between the voltage conversion circuit and the data transmission terminal; current outputted by the voltage conversion circuit flows through paths where the voltage output terminal and the data transmission terminal are arranged, such that the path where the data transmission terminal is arranged can be utilized for charging, which increases charging current and improves charging speed.

Description

technical field [0001] The invention relates to the technical field of intelligent mobile terminals, in particular to a charger charging circuit, a mobile terminal charging circuit, a charger and a mobile terminal. Background technique [0002] With the development and popularization of smart mobile terminals, users have higher and higher requirements for mobile terminals. In addition to requiring mobile terminals to have rich functions, mobile terminals are also required to be able to achieve fast charging and have sufficient battery life. By increasing the charging speed and shortening the user's waiting time for charging, the user experience can be significantly improved. At present, when standard USB sockets and USB cables are used, the maximum current that can be transmitted during charging is restricted by the USB protocol. For example, the maximum transmission current supported by the type-C interface is 5A. When a higher current charging is required, Vbus overcurrent...
