Li-ion/Li Polymer Battery Charger
The ISL6292C is an integrated single-cell Li-ion or
Li-polymer battery charger capable of operating with an input
voltage as low as 2.4V. This charger is designed to work with
various types of ac adapters.
The ISL6292C operates as a linear charger when the ac
adapter is a voltage source. The battery is charged in a
CC/CV (constant current/constant voltage) profile. The
charge current is programmable with an external resistor up
to 1.5A. The ISL6292C can also work with a current-limited
adapter to minimize the thermal dissipation, in which case
the ISL6292C combines the benefits of both a linear charger
and a pulse charger.
The ISL6292C features charge current thermal foldback to
guarantee safe operation when the printed circuit board is
space limited for thermal dissipation. Additional features
include preconditioning of an over-discharged battery,
automatic recharge, and thermally enhanced DFN package.
Ordering Information
NOTE: 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.
