Charger Accepts Wide Range
of Voltages
Intersil’s AnyAdapter ISL6292 lithium ion/polymer
battery charger IC accepts a wide range of voltage
sources. The low-noise linear source is suited
to smart phones or PDA applications and comes
in a flat no-lead package that offers high thermal
efficiency.
Working from a 4.2V to 7V input, the ISL6292 operates
in the traditional pre-charge, constant-current,
constant-voltage sequence with the device’s
Thermaguard temperature-controlled charge-rate
protection circuitry.
The internal, current-trimmed current-sense circuit
guarantees 10% charging accuracy at 4.1V or 4.2V.
It provides a fully programmable end-of-charge
point, but allows charging to continue until the
chip’s safety timer automatically terminates
it.
Priced at 95 cents each in 1,000s, the ISL6292
is also offered in a 16-pad 4 x 4mm QFN and a
16-pad 5 x 5mm QFN. Evaluation boards are available,
the ISL6292EVAL1 for the 3 x 3 DFN, and the -EVAL2
for the 4 x 4 QFN.
