BQ3055DBTR

BQ3055DBTR from Texas Instruments is a Integrated Circuit 2-series, 3-series, and 4-series Li-ion battery pack manager - Battery fuel gauges. The bq3055 device is a fully integrated, single-chip, pack-based solution that provides a rich array of features for gas gauging, protection, and authentication for 2-series, 3-series, and 4-series cell Li-Ion and Li-Polymer battery packs. Using its integrated high-performance analog peripherals, the bq3055 device measures and maintains an accurate record of available capacity, voltage, current, temperature, and other critical parameters in Li-Ion or Li-Polymer batteries, and reports this information to the system host controller over an SMBus v1.1 compatible interface. The bq3055 provides software-based 1st-level and 2nd-level safety protection for overvoltage, undervoltage, overtemperature, and overcharge conditions, as well as hardware-based protection for overcurrent in discharge and short circuit in charge and discharge conditions. SHA-1 authentication with secure memory for authentication keys enables identification of genuine battery packs beyond any doubt. The compact 30-lead TSSOP package minimizes solution cost and size for smart batteries while providing maximum functionality and safety for battery gauging applications.
