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. When supplying
the load and battery charger simultaneously, the input
current limit for the AC adapter is programmable to within
3% accuracy to avoid overloading the AC adapter, and to
allow the system to make efficient use of available adapter
power for charging. It also has a wide range of
programmable charging current. The ISL6251, ISL6251A
provides outputs that are used to monitor the current drawn
from the AC adapter, and monitor for the presence of an AC
adapter. The ISL6251, ISL6251A automatically transitions
from regulating current mode to regulating voltage mode.

NOTES:
1. Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and
100% matte tin plate termination finish, which are RoHS
compliant and compatible with both SnPb and Pb-free soldering
operations. Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the
Pb-free requirements of IPC/JEDEC J STD-020.
2. Add “-T” for Tape and Reel.
