Part Number: ISL6251
Function: Low Cost Multi Chemistry Battery Charger Controller
Package: QFN 28 Pin, QSOP 24 Pin Type
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 loadefficiency and prevent system bus boosting.
