APM8600 Datasheet | Diodes Incorporated

NOT REMENDED FOR NEW DESIGN Green 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 precharging 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.
