What is the most relevant guide to the impedance track algorithm used in the BQ27426?

SLUA450/SLUA422 are 8-9 years old, and SLUA364/SLUA375 are each 10 years old.

What is the best resource for understanding how the BQ27426 works?

Thanks, Best, S. Dunbar, AFA Colorado

Hi Antennahead,

bq27426 is an impedance track lite gauge. It uses the same algorithm as other impedance track gauges but with less flexibility as some parameters hard-coded such as the ChemID. It is meant to have a more simplified development and usage and will enjoy the same advantages as TI's other impedance track gauges.

SLUA450/SLUA422 are still applicable to this device and would be good places to start. I can answer any follow-up questions you may have.

Best Regards,
Ben Lough

Thanks for clarifying.

I think it would be helpful if these rather old documents were updated to reflect some of these Lite gauges.

Sure, I'll pass along your feedback to the rest of the team.
