BQ40Z80: Are there any reference designs?

Part Number: BQ40Z80
Other Parts Discussed in Thread: BQ78350, BQ76930

I am planning to use BQ40Z80 on my BMS but I am not able to find any reference designs for the same.

I'm also confused between BQ76930+BQ78350 and BQ40Z80 for my 3P6S battery pack for my LEV. I feel the BQ40Z80 is a complete solution with more accurate gauging and many additional features. I am a beginner and I think this will be great choice for me. What is TURBO Mode 2.0/Intel® Dynamic Battery Power Technology? Is BQ40Z80 specially made for laptop battery packs? 

What do these two offer over each other? When should I select one over the other?

    Hi,

    We're happy that you are looking into our parts for your LEV. Yes, the bq40z80 is more accurate of the two, however the bq76930 is a longer and more proven design. It has been verified with high currents as well, so in your application where I think there's a high load it might be the better choice. The bq40z80 doesn't have a reference design yet and the evm was tested up to 10A, we are working on a 40A design but that might be some time before it's released. Yes, the Intel TM2 feature is for laptops.

    Considering your experience level, I think the bq76930 might be the better choice.

    Hello,

    Thank You! What I'm interested in BQ40z80 is the charge management algorithms and the cell balancing feature. Is there any way to port it on the BQ76930? Or is there any other solution that I can use to add these features to the BQ76930?

    Hi,

    Unfortunately no. The 2 products are based on very different gauging algorithms. You can get balancing on the bq78350 can do balancing.

    You will have to choose one or the other. In your case, the bq76930 seems to be a better fit as it is proven.
