NOT RECOMMENDED FOR NEW DESIGN Green APM8600 SINGLE CELL LINEAR LITHIUM BATTERY CHARGER WITH 28V OVP AND PROGRAMMABLE CHARGE TIMER Description Pin Assignments BAT 1 14 FLT The APM8600 is a linear Li-Ion charger for portable DC SETI 2 13 equipment that is optimized for small form-factor applications. 3 12 THM DC 4 APM8600 11 GND CHG The charge algorithm in the APM8600 covers all the charge requirements for a single Li-Ion battery cell. Included is pre- 5 10 CT POK charging for deeply discharged cells, constant current / 6 9 DNC NC constant voltage fast charging and a top-off feature to bring 7 8 NC EN the cell safely to a full-charge level. Figure 1 Pin Out The battery is constantly monitored for overvoltage, charge time and cell temperature to ensure safe charging. A fault is Applications 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 Handheld Consumer Devices close to the battery cell. Cell Phones, PDAs, MP3 Players The APM8600 is packaged in U-DFN3030-14 package with Handheld Test Equipment a thermal pad.
