NCP1835B Integrated Li-Ion Charger

Pin Symbol Description 1 VCC Input Supply Voltage. Provides power to the charger. This pin should be bypassed with at least a 4.7 mF ceramic capacitor to ground. 2 FAULT An open *drain output indicating fault status. This pin is pulled LOW under any fault conditions. A FAULT condition rese.

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.
