Description

The ACE4101 is a 1.6A Li‐Ion battery switching charger intended for 5V adapters. Low power

dissipation, an internal MOSFET and its compact package with minimum external components

requirement makes the ACE4101 ideal for portable applications. The ACE4101 includes complete charge

termination circuitry, automatic recharge and a ±1% 4.2V/4.35V float voltage.

External sense resistor and Reverse diode is not need. Build‐in thermal feedback mechanism regulates

the charge current to control the die temperature during high power operation or at elevated ambient

temperature.

Battery charge current, charge timeout and end-of‐charge indication parameters can program by

external components. Additional features include shorted cell detection and overvoltage protection.

Features

 Very Low Power Dissipation

 1.6A Maximum Charge Current

 Standalone Capability with no Requirement of External MOSFET, Sense Resistor or Blocking Diode

 Constant‐Current/Constant‐Voltage Operation with Thermal Regulation to Maximize Charge Rate

Without Risk of Overheating

 Charges Single Cell Li‐Ion Batteries Directly from USB Port

 Drainage Charge Current Thermal Regulation Status Outputs for LED or System Interface

 Preset 4.2V/4.35V float Voltage with ±1% Accuracy

 Automatic Recharge

Application

 Cellular Telephones, PDA, MP3 Players

 Charging Docks and Cradles

 Handheld Battery‐Powered Devices

 Handheld Computers
