Working Principles

The MAX713ESE+T operates on a CC/CV charging algorithm. It starts by supplying a constant current to the battery until the battery voltage reaches a predetermined threshold. Then, it switches to a constant voltage mode, where the charging current gradually decreases as the battery approaches full capacity.

The IC continuously monitors the battery temperature using an external thermistor connected to the THERM pin. If the temperature exceeds a certain limit, the IC activates thermal shutdown to protect the battery and itself from damage.
