•
•
Supports the Smart Battery Specification  
SBS V1.1  
The bq20z65-R1 SBS-compliant gas gauge and  
protection IC, incorporating patented Impedance  
Track™ technology, is a single IC solution designed  
for battery-pack or in-system installation. The  
bq20z65-R1 measures and maintains an accurate  
record of available charge in Li-ion or Li-polymer  
batteries using its integrated high-performance  
analog peripherals. The bq20z65-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. Together  
with the integrated analog front-end (AFE)  
short-circuit and overload protection, the bq20z65-R1  
maximizes functionality and safety while minimizing  
external component count, cost, and size in smart  
battery circuits.  
Flexible Configuration for 2 to 4 Series Li-Ion  
and Li-Polymer Cells  
Powerful 8-Bit RISC CPU With Ultralow Power  
Modes  
Full Array of Programmable Protection

Lifetime Data Logging  
Drives 3, 4, and 5 Segment LED Display for  
Battery-Pack Conditions  
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.
