ISL6298
Li-ion/Li-Polymer Battery Charger
The ISL6298 is an integrated single-cell Li-ion or Li-polymer
battery charger optimized for low current applications. The
targeted applications include mini-disk (MD) players, Blue
Tooth headsets, or other applications that use low-capacity
battery cells.
The ISL6298 is a linear charger that charges the battery in a
CC/CV (constant current/constant voltage) profile. The
charge current is programmable with an external resistor up
to 450mA during the CC phase. Once the battery voltage
reaches 4.2V (or 4.1V), the charger enters CV mode and the
charge current starts to reduce. When the charger current
drops to a user-programmable threshold, the charger
indicates the end-of-charge with a STATUS pin. The charger
does not actually terminate until a user-programmable total
fast charge time is reached. If the battery voltage drops to a
recharge threshold after termination, the charger will re-
charge the battery to its full capacity. The charger
preconditions the battery with 20% of the programmed CC
current if the battery voltage is below 2.8V. The total
precharge time is limited to 1/8 of the total fast charge time.
The ISL6298 features charge current thermal foldback to
guarantee safe operation when the printed circuit board is
space-limited for thermal dissipation. Additional features
include an NTC thermistor interface for monitoring the
ambient temperature, the ability to disable the time limit of
the fast charge, an FAULT indication, and a thermally
enhanced QFN or 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.
