ACE4101 fiche technique
ACE4101
Max. 1.6A Li-ion Switching Charger IC
Description
The ACE4101 is a 1.6A LiIon 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. Buildin 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-ofcharge indication parameters can program by
external components. Additional features include shorted cell detection and overvoltage protection.
