ISL6255, ISL6255A
Highly Integrated Battery Charger with
Automatic Power Source Selector for
Notebook Computers
The ISL6255, ISL6255A is a highly integrated battery charger
controller for Li-Ion/Li-Ion polymer 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
also be 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
ISL6255, ISL6255A provides outputs that are used to monitor
the current drawn from the AC adapter, and monitor for the
presence of an AC adapter. The ISL6255, ISL6255A
automatically transitions from regulating current mode to
regulating voltage mode.
ISL6255, ISL6255A has a feature for automatic power source
selection by switching to the battery when the AC adapter is
removed or switching to the AC adapter when the AC adapter
is available. It also provides a DC adapter monitor to support
aircraft power applications with the option of no battery
charging.

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.
