Battery Charger and Step-Down Converter for Portable Applications General Description The AAT2556 is a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product family. It is a fully integrated 500mA battery charger plus a 250mA step-down converter. The input voltage range is 4V to 6.5V for the battery charger and 2.7V to 5.5V for the step-down converter, making it ideal for single-cell lithium-ion/polymer batterypowered applications. The battery charger is a complete constant current/ constant voltage linear charger. It offers an integrated pass device, reverse blocking protection, high current accuracy and voltage regulation, charge status, and charge termination. The charging current is programmable via external resistor from 15mA to 500mA.
