Charging management system and charger with the same

摘要

The present invention discloses a charging management system and a charger with such charging management system. The charging management system includes a first signal-output port, a second signal-output port, a third signal-output port and a controller electrically connected with the first, second and third signal-output ports. The first and second signal-output ports are adapted for outputting first and second control signals representing first and second charging currents, respectively, to a charging circuit. The third signal-output port is adapted for outputting a third control signal representing a variable third charging current to the charging circuit. The controller controls the charging management system to operate under at least one of two modes. In the first mode, the controller alternately controls the first and second signal-output ports to output the first and second control signals. In the second mode, the controller only controls the third signal-output port to output the third control signal.
