Abstract
Official abstract text for this publication.
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.
