NCP1835
Integrated LiIon Charger
NCP1835 is an integrated linear charger specifically designed to
charge 1
cell Li
Ion batteries with a constant current, constant
voltage (CCCV) profile. It can charge at currents of up to 1.0 A.
Its low input voltage capability, adjustable charge current, ability
to maintain regulation without a battery, and its onboard thermal
foldback make it versatile enough to charge from a variety of wall
adapters. The NCP1835 can charge from a standard voltage
source
wall adapter as a CCCV charger, or from a current limited adapter to
limit power dissipation in the pass device.
