The AAT2557 is a fully integrated 500mA battery charger and a 300mA low dropout (LDO) linear regulator. The input voltage range is 4V to 6.5V for the battery charger and 2.7V to 5.5V for the linear regulator, making it ideal for applications operating with single-cell lithium-ion/polymer batteries. The battery charger is a complete constant current/constant voltage linear charger. It offers an integrated pass device, reverse blocking protection, high accuracy current and voltage regulation, charge status, and charge termination. The charging current is programmable via external resistor from 15mA to 500mA. In addition to these standard features, the device offers over-voltage, current limit, and thermal protection. The linear regulator is designed for fast transient response and good power supply ripple rejection. Capable of up to 300mA load current, it includes short-circuit protection and thermal shutdown. The AAT2557 is available in a Pb-free, thermally-enhanced TSOPJW-14 package and is rated over the -40°C to +85°C temperature range.
