Description

The APM8600 is a linear Li-Ion charger for portable

equipment that is optimized for small form-factor

applications.

The charge algorithm in the APM8600 covers all the charge

requirements for a single Li-Ion battery cell. Included is pre-

charging for deeply discharged cells, constant current /

constant voltage fast charging and a top-off feature to bring

the cell safely to a full-charge level.

The battery is constantly monitored for overvoltage, charge

time and cell temperature to ensure safe charging. A fault is

triggered once the charge time exceeds a value that is

programmable using a single capacitor and the temperature

measurement is achieved through a thermistor positioned

close to the battery cell.

The APM8600 is packaged in U-DFN3030-14 package with

a thermal pad.
