DATASHEET ISL6251, ISL6251A Low Cost Multi-Chemistry Battery Charger Controller FN9202 Rev 3.00 March 13, 2014 The ISL6251, ISL6251A is a highly integrated battery charger controller for Li-Ion/Li-Ion polymer batteries and NiMH batteries. High efficiency is achieved by a synchronous buck topology and the use of a MOSFET, instead of a diode, for selecting power from the adapter or battery. The low side MOSFET emulates a diode at light loads to improve the light load efficiency and prevent system bus boosting. The constant output voltage can be selected for 2, 3 and 4 series Li-Ion cells with 0.5% accuracy over-temperature. It can be also programmed between 4.2V+5%/cell and 4.2V-5%/cell to optimize battery capacity.
