1.0 A One-Cell Lithium-ion/Polymer Battery 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.
