NCP1835B
Integrated Li鈭捍on Charger
NCP1835B is an integrated linear charger specifically designed to
charge 1鈭抍ell Li鈭捍on 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鈭抌ased MP3 players. It鈥檚 recommended charge current rate
is 30鈭?00 mA.
