Li-ion/Li Polymer Battery Charger
The ISL9203R5220 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 ISL9203R5220 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 ISL9203R5220 can also work with a current-
limited adapter to minimize the thermal dissipation, in which
case the ISL9203R5220 combines the benefits of both a
linear charger and a pulse charger.
The ISL9203R5220 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 and thermally enhanced DFN package.
Typical Application Circuit
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.
