Li-ion/Li Polymer Battery Charger

Features

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.

• Complete Charger for Single-Cell Li-ion Batteries

• Very Low Thermal Dissipation

• Integrated Pass Element and Current Sensor

• No External Blocking Diode Required

• 1% Voltage Accuracy

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.

• Programmable Current Limit up to 1.5A

• Charge Current Thermal Foldback

• Accepts Multiple Types of Adapters

• Guaranteed to Operate at 2.65V After Start Up

• Ambient Temperature Range: -20°C to 70°C

• Thermally-Enhanced DFN Packages

• Pb-Free Plus Anneal Available (RoHS Compliant)

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.

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.
