ISL6251 datasheet



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.

Featrues :

1. Output for Current Drawn from AC Adapter

2. AC Adapter Present Indicator

3. Fast Input Current Limit Response

4. Input Voltage Range 7V to 25V

5. Supports 2, 3 and 4 Cells Battery Pack

6. Up to 17.64V Battery-Voltage Set Point

7. Thermal Shutdown

8. Support Pulse Charging

9. Less than 10μA Battery Leakage Current

10. Charge Any Battery Chemistry: Li-Ion, NiCd, NiMH, etc.

11. Pb-Free (RoHS Compliant)




1. Notebook, Desknote and Sub-notebook Computers

2. Personal Digital Assistant
