BQ3050DBTR

BQ3050DBTR from Texas Instruments is a Integrated Circuit SBS 1.1-compliant 2-s to 4-s battery gas gauge & protection - Battery fuel gauges. The Texas Instruments bq3050 Compensated End-of-Discharge Voltage (CEDV) Gas Gauge and Battery Pack Manager is a single-chip solution that provides a rich array of features for protection, authentication, and data gathering for 2-series, 3-series, and 4-series cell Li-Ion and Li-Polymer battery packs. Using its integrated high-performance analog peripherals, the bq3050 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 bq3050 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 38-lead TSSOP package minimizes solution cost and size for smart batteries while providing maximum functionality and safety for battery gauging applications.
