AAT3663 1A Linear Li-Ion Battery Charger for Single and Dual Cell Applications General Description www.datasheet4u.com Features • • • • • • • • • • • • • • • • BatteryManager™ The AAT3663 BatteryManager™ is a member of AnalogicTech’s Total Power Management IC™ family. This device is an integrated single/dual cell Lithium-Ion (Li-Ion) / polymer battery charger IC designed to operate from USB ports or an AC adapter inputs up to an input voltage of 13.2V. AAT3663 precisely regulates battery charge voltage and current for 4.2V and 8.4V Li-Ion battery cells. The battery charging current is user programmed up to 1A by an external resistor. Battery charge state is continuously monitored for fault conditions. A Digital Thermal Loop Control maintains the maximum possible battery charging current for the optimum set of input to output power dissipation and ambient temperature conditions. In the event of an over-current, over-voltage, shortcircuit, or over-temperature fault condition, the device will automatically shut down, thus protecting the charger and the battery under charge. Two status monitor output pins are provided to indicate the battery charge status by directly driving external LEDs. Additionally, an open-drain powersource detection output (ADPP#) is provided to report presence of an input power supply The AAT3663 is available in a thermally enhanced, space-saving, 14-pin 3x3 mm TDFN package and is specified for operation over the -40°C to +85°C temperature range. 4.0V ~ 13.2V Input Voltage Range Compatible with USB or AC Adapter Sources Programmable Fast Charge Current from 100mA to 1A Programmable Charge Termination Current Digital Thermal Loop Charge Reduction Less Than 0.4µA Battery Leakage Current Programming Charge Timer Battery Temperature Sensing Battery Temp Sense Open Circuit Detection Automatic Recharge Sequencing Automatic Trickle Charge for Battery Pre-Conditioning Automatic Charge Termination Shutdown/Sleep Mode Less than 1µA Shutdown Current Over-Voltage and Over-Current Protection Power On Reset and Soft Start 3x3mm 14-pin TDFN Package Applications • • • • • • Bluetooth™ Headset Cell Phones Digital Still Cameras MP3 Players Personal Data Assistants (PDAs) Other Li-Ion Battery Powered Devices Typical Application ON/OFF EN BATS VIN IN BAT BATT+ 10μF BATTTEMP STAT1 STAT2 ADPP# GND TS TERM ISET CT CT RSET R TERM Battery Pack AAT3663 3663.2007.10.1.0 1 AAT3663 1A Linear Li-Ion Battery Charger for Single and Dual Cell Applications Pin Description www.datasheet4u.com Pin # 1 2 3 4 5 6 7 8, 9 10 11 12 13 Symbol EN CT ISET GND TS BATS BAT IN STAT1 STAT2 ADPP# TERM Type I I I I/O I/O I O I O O O I Function Enable pin, Active high with internal pull-down. If not used, pull high to the IN pin to continuously enable the charger IC when input power is applied. Charge timer programming pin. A 0.1µF ceramic capacitor should be connected between this pin and GND. Connect directly to GND to disable the timer function. Charge current.
