MOBILE TERMINAL WITH MULTI-PORT CHARGING CONTROL FUNCTION

摘要

A mobile terminal includes a battery; a first universal serial bus (USB) interface, a central processing unit (CPU), USB charging management module, and a charging management chip. The central processing unit (CPU) is configured to generate an on/off command, and configured to output an adjustment signal. The USB charging management module is configured to turn on or off a charging channel according to the on/off command, and configured to control a value of a charging current according to the adjustment signal, combine the charging current, and transmit the combined charging current to a charging management chip. The charging management chip is configured to transmit the charging current to the battery to charge the battery.
