Product Description

DESCRIPTION
The LTC®4001-1 is a 2A Li-Ion battery charger intended for 5V wall adapters. It utilizes a 1.5MHz synchronous buck converter topology to reduce power dissipation during charging. Low power dissipation, an internal MOSFET and sense resistor allow a physically small charger that can be embedded in a wide range of handheld applications. The LTC4001-1 includes complete charge termination circuitry, automatic recharge and a ±1% 4.1V fl oat voltage. Input short-circuit protection is included so no blocking diode is required.
FEATURES
■ Low Power Dissipation
■ 2A Maximum Charge Current
■ No External MOSFETs, Sense Resistor or Blocking Diode Required
■ Remote Sensing at Battery Terminals
■ Programmable Charge Termination Timer
■ Preset 4.1V Float Voltage with ±0.5% Accuracy
■ 4.1V Float Voltage Improves Battery Life and High Temperature Safety Margin
■ Programmable Charge Current Detection/ Termination
■ Automatic Recharge
■ Thermistor Input for Temperature Qualified Charging
■ Compatible with Current Limited Wall Adapters
■ Low Profi le 16-Lead (4mm × 4mm) QFN Package
APPLICATIONS
■ Handheld Battery-Powered Devices
■ Handheld Computers
■ Charging Docks and Cradles
■ Digital Cameras
■ Smart Phones
