FEATURES
DESCRIPTIO
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 4.2V Float Voltage with ±0.5% Accuracy Programmable Charge Current Detection/Termination Automatic Recharge Thermistor Input for Temperature Qualified Charging Compatible with Current Limited Wall Adapters Low Profile 16-Lead (4mm Ч 4mm) QFN Package
The LTC®4001 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 includes complete charge termination circuitry, automatic recharge and a ±1% 4.2V float voltage. Input short-circuit protection is inc
