•
Next Generation Patented Impedance Track™  
Technology accurately Measures Available  
Charge in Li-Ion and Li-Polymer Batteries  
The bq20z75 SBS-compliant gas gauge and  
protection IC is a single IC solution designed for  
battery-pack or in-system installation. The bq20z75  
measures and maintains an accurate record of  
available charge in Li-ion or Li-polymer batteries  
using its integrated high-performance analog  
peripherals, monitors capacity change, battery  
impedance, open-circuit voltage, and other critical  
parameters of the battery pack as well and reports  
the information to the system host controller over a  
serial-communication bus. Together with the  
integrated analog front-end (AFE) short-circuit and  
overload protection the bq20z75 maximizes  
functionality, safety and minimize external component  
count, cost and size in smart battery circuits.  
–
Better than 1% Error Over Lifetime of the  
Battery

Supports the Smart Battery Specification  
SBS V1.1  
Flexible Configuration for 2 to 4 Series Li-Ion  
and Li-Polymer Cells  
Powerful 8-Bit RISC CPU With Ultra-Low  
Power Modes  
Full Array of Programmable Protection  
Features  
The implemented Impedance Track™ gas gauging  
technology continuously analyzes the battery  
impedance, resulting in superior gas-gauging  
accuracy. This enables remaining capacity to be  
calculated with discharge rate, temperature, and cell  
aging all accounted for during each stage of every  
cycle with high accuracy.
