LTC4001, 2A Synchronous Buck Li-Ion Charger

LTC4001 2A Synchronous Buck Li-Ion Charger .

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 4.2V Float Voltage with ±0.5% Accuracy
* Programmable Charge Current Detec

Applications

* The LTC4001 includes complete charge termination circuitry, automatic recharge and a ±1% 4.2V float voltage. Input short-circuit protection is included so no blocking diode is required. Battery charge current, charge timeout and end-of-charge indication parameters are set with external components.
