ISL6292
Li-ion/Li Polymer Battery Charger
The ISL6292 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 or a USB port.
The ISL6292 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 2A. The ISL6292 can also work with a current-limited
adapter to minimize the thermal dissipation, in which case,
the ISL6292 combines the benefits of both a linear charger
and a pulse charger.
The ISL6292 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, an
NTC thermistor interface for charging the battery in a safe
temperature range, automatic recharge, and thermally
enhanced QFN or DFN packages.
