DESCRIPTION Next Generation Patented Impedance Track™
Technology accurately Measures Available The bq20z75 SBS-compliant gas gauge and
Chargein Li-Ion and Li-Polymer Batteries protection ICisa single IC solution designed for
battery-packor in-system installation. The bq20z75
– Better than 1% Error Over Lifetimeof the measures and maintains an accurate record of
Battery available charge in Li-ion or Li-polymer batteries
– Instant Accuracy– No Learning Cycle using its integrated high-performance analog
Required peripherals, monitors capacity change, battery
Supports the Smart Battery Specification impedance, open-circuit voltage, and other critical
parametersof the battery pack as well and reports
SBS V1.1the informationto the system host controller overa
• Flexible Configuration for2to4 Series Li-Ion serial-communication bus. Together with the
and Li-Polymer Cells integrated analog front-end (AFE) short-circuit and
• Powerful 8-Bit RISC CPU With Ultra-Low overload protection the bq20z75 maximizes
Power Modes functionality, safety and minimize external component
count, cost and sizein smart battery circuits.
• Full Arrayof Programmable Protection
Features The implemented Impedance Track™ gas gauging
technology continuously analyzes the battery
– Voltage, Current and Temperatureimpedance, resulting in superior gas-gauging
• Supports SHA-1 Authentication accuracy. This enables remaining capacity to be
• small 38-Pin TSSOP (DBT) Package calculated with discharge rate, temperature, and cell
aging all accounted for during each stageof every
APPLICATIONS cycle with high accuracy.
