Product Overview

The LTC4001EUF#PBF 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 included so no blocking diode is required. Battery charge current, charge timeout and end-of-charge indication parameters are set with external components. Additional features include shorted cell detection, temperature qualified charging and overvoltage protection.
  • Low power dissipation
