ISL6251A Low Cost Multi-Chemistry Battery Charger Controller

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 syst.
