DESCRIPTION  
Supports the Smart Battery Specification  
SBS V1.1  
The bq20z60-R1 SBS-compliant gas gauge and  
protection IC, incorporating patented Impedance  
Track™ technology, is designed for battery-pack or  
in-system installation. The bq20z60-R1 measures  
and maintains an accurate record of available charge  
in Li-ion or Li-polymer batteries using its integrated  
Flexible Configuration for 2 to 4 Series Li-Ion  
and Li-Polymer Cells  
Powerful 8-Bit RISC CPU With Ultralow Power  
Modes  
high-performance  
analog  
peripherals.  
The  
bq20z60-R1 monitors capacity change, battery  
impedance, open-circuit voltage, and other critical  
parameters of the battery pack, which 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.  
Full Array of Programmable Protection  
Features  
Voltage, Current, and Temperature  
Satisfies JEITA Guidelines  
Added Flexibility to Handle More Complex  
Charging Profiles  
Lifetime Data Logging  
Drives 3, 4, or 5 Segment LED Display for  
Battery-Pack Conditions  
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 with high accuracy.  
Supports SHA-1 Authentication  
Available in a 30-Pin TSSOP (DBT) package
