CHARGING CIRCUIT, ELECTRONIC DEVICE, CHARGING CONTROL METHOD AND DEVICE

A charging circuit (110) applied to a first electronic device includes a charging interface (120), a charging module (130) coupled therewith and configured to detect a connection between the charging interface (120) and a second electronic device, and adjust a current output to the second electronic device, a reverse charging protocol module (140), and a control module (150). The reverse charging protocol module (140) is configured to determine a reverse charging protocol matched with the charging current of the second electronic device. The control module (150) is coupled with the charging module (130) and the reverse charging protocol module (140), and configured to acquire the reverse charging protocol determined by the reverse charging protocol module (140) in response to the connection between the charging interface (120) and the second electronic device, and control the charging module(130) to adjust the current output to the second electronic device based on the reverse charging protocol. The charging circuit can increase the reverse charging current.
