•
Next Generation Patented Impedance Track™  
Technology Accurately Measures Available  
Charge in Li-Ion and Li-Polymer Batteries  
The bq20z40-R1 SBS-compliant gas gauge and  
protection IC, incorporating patented Impedance  
Track™ technology, is designed for battery-pack or  
in-system installation. The bq20z40-R1 measures  
and maintains an accurate record of available charge  
in Li-ion or Li-polymer batteries using its integrated  
–
Better Than 1% Error Over the Lifetime of  
the Battery

•
Supports the Smart Battery Specification  
SBS V1.1  
high-performance  
analog  
peripherals.  
The  
Flexible Configuration for 2 to 4 Series Li-Ion  
and Li-Polymer Cells  
bq20z40-R1 monitors capacity change, battery  
impedance, open-circuit voltage, and other critical  
parameters of the battery pack, and reports the  
information to the system host controller over a  
serial-communication bus. It is designed to work with  
the bq29330 analog front-end (AFE) protection IC to  
maximizes functionality and safety while minimizing  
external component count and cost in smart battery  
circuits.  
Powerful 8-Bit RISC CPU With Ultralow Power  
Modes  
Full Array of Programmable Protection  
Features  
–
Voltage, Current, and Temperature  
•
•
Satisfies JEITA Guidelines  
The Impedance Track™ technology continuously  
analyzes the battery impedance, resulting in superior  
gas-gauging accuracy. This enables the remaining  
capacity to be calculated with discharge rate,  
temperature, and cell aging that are all accounted for  
during each stage of every cycle.  
Added Flexibility to Handle More Complex  
Charging Profiles
