BQ20Z95DBTR

BQ20Z95DBTR TEXAS INSTRUMENT The bq20z95 SBS-compliant gas gauge and protection IC is a single IC solution designed for Charge in Li-Ion and Li-Polymer Batteries battery-pack or in-system installation. The bq20z95 - Better Than 1% Error Over Lifetime of the measures and maintains an accurate record of Battery available charge in Li-Ion or Li-Polymer batteries - Supports the Smart Battery Specification using its integrated high-performance analog SBS V1.1 peripherals, monitors capacity change, battery impedance, open-circuit voltage, and other critical - Flexible Configuration for 2-Series to 4-Series parameters of the battery pack as well and reports Li-Ion and Li-Polymer Cells the information to the system host controller over a - Powerful 8-Bit RISC CPU With Ultra-Low serial-communication bus. Together with the Power Modes integrated analog front-end (AFE) short-circuit and overload protection, the bq20z95 maximizes - Full Array of Programmable Protection functionality and safety while minimizing external Features component count, cost, and size in smart battery - Voltage, Current, and Temperature circuits. - Supports SHA-1 Authentication The implemented Impedance Track gas gauging - Complete Battery Protection and Gas Gauge technology continuously analyzes the battery Solution in One Package impedance, resulting in superior gas-gauging - Small 44-Pin TSSOP (DBT) Package accuracy. This enables remaining capacity to be calculated with discharge rate, temperature, and cell APPLICATIONS aging all accounted for during each stage of every cycle with high accuracy
