Description

The AAT3680 BatteryManager™ is a member of AnalogicTech's Total Power Management IC™ family. This device AAT3680 is an advanced Lithium-Ion (Li- Ion) battery charge and management IC, specifically designed for low cost compact portable applications. In a single 8-pin package, the AAT3680 precisely regulates battery charge voltage and charge current. This device is capable of two trickle charge current levels controlled by one external pin. Battery charge temperature and charge state are carefully monitored for fault conditions. In the event of an over current, short circuit or over temperature failure, the device will automatically shut down, thus protecting the charging device AAT3680 and the battery under charge. A battery charge state monitor output pin is provided to indicate the battery charge status though 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 an 8-pin MSOP or 12-pin TSOPJW package, specified over -20 to 70°C range.
