USB Port Lithium-Ion/Polymer Battery Charger

USB Port Lithium-Ion/Polymer Battery Charger General Description The AAT3688 BatteryManager™ is a highly integrated single cell lithium-ion/polymer battery charger IC designed to operate with USB port inputs. It requires the minimum number of external components. The AAT3688 precisely regulates battery charge voltage and current for 4.2V lithium-ion/polymer battery cells. Depending on the USB port type, the AAT3688 charge current can be programmed for two separate levels up to 500mA. An optional Charge Reduction Loop is built in to allow users to charge the battery with available current from a USB port, while keeping the port voltage regulated. AAT3688 Features • • • BatteryManager™ 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 Applications directly driving two external LEDs. A serial interface www.DataSheet4U.com output is available to report any one of 14 various • Bluetooth™ Headsets status states to a microcontroller. • Cellular Telephones • Digital Still Cameras The AAT3688 is available in a Pb-free, thermally• Hand-Held PCs enhanced, space-saving 12-pin 3x3mm TDFN • MP3 Players package and is rated over the -40°C to +85°C tem• Personal Data Assistants (PDAs) perature rang.
