NCP1835B Datasheet Integrated Li-ion Charger

Manufacturer: onsemi

Overview: 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. It has been optimized to charge low capacity batteries such as those found in wireless headsets and flash memory−based MP3 players.
