NCP1835 Datasheet | onsemi

Integrated Li-Ion Charger NCP1835 is an integrated linear charger specifically designed to charge 1- cell Li- Ion batteries with a constant current, constant voltage (CCCV) profile. It can charge at currents of up to 1.0 A. 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 NCP1835 can charge from a standard voltage- source wall adapter as a CCCV charger, or from a current limited adapter to limit power dissipation in the pass device. Features - Integrated Voltage and Current Regulation - No External MOSFET, Sense Resistor or Blocking Diode Required - Charge Current Thermal Foldback - Integrated Pre- charge Current for Conditioning Deeply Discharged Battery - Integrated End- of- Charge (EOC) Detection - 1% Voltage Regulation - 4.2 V or 4.242 V Regulated Output Voltage - Regulation Maintained without a Battery Present - Programmable Full Charge Current 300 - 1000 m A - Open- Drain Charger Status and Fault Alert Flags - 2.8 V Output for AC Present Indication and Powering Charging Subsystems - Minimum Input Voltage of 2.4 V Allows Use of Current Limited Adapters - Automatically Recharging if Battery Voltage Drops after Charging Cycle is pleted - Low Profile 3x3 mm DFN Package - Pb- Free Packages are Available Typical Applications - Cellular Phones - PDAs, MP3 Players - Stand- Alone Chargers - Battery Operated Devices http://onsemi.
