Overview

DATASHEET ISL6251, ISL6251A Low Cost Multi-Chemistry Battery Charger Controller 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.
