NCP1835B Integrated Li Ion Charger NCP1835B is an integrated linear charger specifically designed to charge 1 cell Li Ion batteries with a constant current, constant voltage (CCCV) profile.

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 NCP1835B can charge from a standard wall adapter or from the USB port
