AAT3685 | Lithium-Ion/Polymer Battery Charger

The AAT3685 BatteryManager is a member of AnalogicTech's Total Power Management IC (TPMIC) product family. This device is a highly integrated single cell lithium-ion/polymer Battery Charger IC designed to operate with USB port or line adapter inputs. It requires the minimum number of external components. The AAT3685 precisely regulates battery charge voltage and current for 4.2V lithium-ion/polymer battery cells. Depending upon input power source, whether it be a USB port or line adapter, the AAT3685 may be programmed for two separate constant current charge levels up to 1A. An optional Charge Reduction Loop is built in to allow users to charge the battery with available current from the charge supply, while keeping the port voltage regulated. Battery temperature and charge state are fully monitored for fault conditions. In the event of an over-voltage or over-temperature failure, the device will automatically shut down, thus protecting the charging device, control system, and the battery under charge. Status monitor output pins are provided to indicate the battery charge status by directly driving two external LEDs A serial Interface output is available to report any one of 14 various status states to a Microcontroller The AAT3685 is available in a Pb-free, thermally-enhanced, space-saving 12-pin 3x3mm TDFN package and is rated over the -40C to +85C temperature range.
