AAT3663 SHEET1A Linear Li-Ion Battery Charger for Single and Dual Cell Applications

The AAT3663 BatteryManager™ is a member of SKYWORKS' 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, short-circuit, 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 power-source 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 3 × 3 mm TDFN package and is specified for operation over the -40°C to +85°C temperature range.
