SLUS686B–NOVEMBER 2005–REVISED JULY 2007
SBS 1.1-COMPLIANT GAS GAUGE ENABLED WITH IMPEDANCE TRACK™
TECHNOLOGY FOR USE WITH THE bq29330 Notebook PCs•
Next Generation Patented Impedance Track™
Technology accurately Measures Available •
Medical and Test Equipment
Chargein Li-Ion and Li-Polymer Batteries •
Portable Instrumentation Better than 1% Error Over Lifetimeof the
Battery Instant Accuracy– No Learning Cycle The bq20z70 SBS-compliant gas gauge IC,
Required incorporating patented Impedance Track™
technology,is designed for battery-packor in-system•
Supports the Smart Battery Specification SBS installation. The bq20z70 measures and maintains
V1.1 an accurate recordof available chargein Li-ionor•
Powerful 8-Bit RISC CPU With Ultra-Low Li-polymer batteries using its integrated
Power Modes high-performance analog peripherals. The bq20z70
monitors capacity change, battery impedance,•
Works With theTI bq29330 Analog Front-Endopen-circuit voltage, and other critical parametersof
(AFE) ProtectionICto Provide Complete Packthe battery pack, and reports the informationto the
Electronics Solution system host controller overa serial-communication•
Full Arrayof Programmable Protection bus.Itis designedto work with the bq29330 analog
Features front-end (AFE) protection IC to maximize
Voltage, Current and Temperature functionality and safety, and minimize component
count and costin smart battery circuits.•
Fully Integrated High Accurate Clock Flexible Configuration for2to4 Series Li-Ion The Impedance Track technology continuously
analyzes the battery impedance, resultingin superior
and Li-Polymer Cellsgas-gauging accuracy. This enables remaining•
