Abstract
A charging circuit and a control method for charging different brands of mobile devices are disclosed. The charging circuit comprises: a universal interface connected to a mobile device to be charged; a charging adaptation unit comprising at least two types of charging circuitries, wherein the charging adaptation unit is connected to the universal interface and configured to provide a corresponding charging circuitry for the mobile device; a voltage conversion unit connected to a charging power source and configured to adjust an output voltage of the charging power source to a charging voltage for the mobile device; and a current detection unit connected between the voltage conversion unit and the charging adaptation unit and configured to detect a charging current, wherein the charging current is configured to determine the corresponding charging circuitry for the mobile device. The charging circuit and the control method thereof can charge different brands of mobile devices by means of a single universal interface, and can also charge a mobile device by means of another mobile device, which makes the use of mobile devices more convenient.

8. A control method of a charging circuit, the control method including:
-
using, by a charging adaptation unit, a first circuit as a charging circuitry for a mobile device by default; determining, by the charging adaptation unit, whether a first current value corresponding to a charging voltage of the first circuit is larger or smaller than a first threshold thereby obtaining a first determination result; and controlling, by the charging adaptation unit, the first circuit to charge the mobile device when the first determination result is that the first current value is larger than the first threshold. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
