APM8600
SINGLE CELL LINEAR LITHIUM BATTERY CHARGER
WITH 28V OVP AND PROGRAMMABLE CHARGE TIMER
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.
