A4055 Datasheet - AiT Semiconductor

A4055 - 800mA STANDALONE LINEAR LI-ION BATTERY CHARGER

The A4055 is a complete constant-current / constant-voltage linear charger for single cell lithium-Ion batteries. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. Thermal feedback regulates the charge current to limit the die temperatur.

A4055 Features

* include charge current monitor, under-voltage lockout, automatic recharge and a status pin to indicate charge termination and the presence of an input voltage. The A4055 is available in SOT-25 Package FEATURES

* Programmable Charge Current Up to 800mA

* No MOSFET, Sense Resistor or Blocking
