300 mA One-Cell Lithium-ion/Polymer Battery 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. The recommended charge current rate is 30-300 mA.
