HM5082

3A Synchronous Buck 2 Cells Li-ion Charger

DESCRIPTION

The HM5082 is a 3A Li-Ion battery charger. It utilizes a 500 KHz synchronous buck

converter topology to reduce power dissipation during charging. Low power

dissipation, an internal MOSFET allow a physically small charger that can be

embedded in a wide range of handheld applications. The HM5082 includes complete

charge termination circuitry, automatic recharge and a ±1% 8.4V float voltage. 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. The HM5082 is available in a ESOP8 and

DNF10 package
