1 / 18 page  AAT3680 Lithium-Ion/Polymer Linear Battery Charge Controller 3680.2006.03.1.6 1 BatteryManager™ Typical Application Q1 SMA B34DLA FZT968 AAT3680 C2 1 µF C3 10 µF R2 1k RSENSE 0.2 Ω R1 1.9k BATT+ BATT- TEMP RT1 RT2 VP Battery Pack DRV CSI VP VP VSS STAT TS BAT T2X LED1 General Description The AAT3680 BatteryManager is a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product family. This device is a lithium- ion/polymer battery charge and management IC, specifically designed for compact portable applica- tions. The AAT3680 precisely regulates battery charge voltage and charge current, and is capable of two trickle charge current levels controlled by one external pin. Battery charge temperature and charge state are carefully monitored for fault con- ditions. In the event of an over-current, short-cir- cuit, or over-temperature failure, the device will automatically shut down, protecting the charging device and the battery under charge. A battery charge state monitor output pin is provided to indi- cate the battery charge status through a display LED. The battery charge status output is a serial interface which may also be read by a system microcontroller. The AAT3680 is available in a Pb-free, 8-pin MSOP or 12-pin TSOPJW package, specified over the -20°C to +70°C temperature range. Features • Input Voltage Range: 4.5V to 7V • 1% Accurate Preset Voltages: 4.1V, 4.2V • Low Operation Current, Typically 0.5mA • Programmable Charge Current • Automatic Recharge Sequencing • Battery Temperature Monitoring • Deep Discharge Cell Conditioning • Fast Trickle Charge Option with Thermal Over-Ride • Full Battery Charge Auto Turn-Off / Sleep Mode • Over-Voltage, Over-Current, and Over- Temperature Protection • Power On Reset • LED Charge Status Output or System Microcontroller Serial Interface • Temperature Range: -20°C to +70°C • 8-Pin MSOP or 12-Pin TSOPJW Package Applications • Cellular Phones • Desktop Chargers • Personal Digital Assistants (PDAs) • USB Chargers |
