MM3746 series are protection ICs with charger pump and drive high side N channel FET for Lithium-ion and
Lithium-polymer secondary battery. This IC is suitable for the advanced battery packs which communicate data between the battery pack and the system. MM3746 has a temperature detection thanks to a NTC Thermistor that protects the battery pack and system from over temperature.
