Hi David,
I suppose if you are attaching the cells individually, this may work. I am concerned about what would happen if one device was in fault mode and the other was not.
Have you looked into some of our 2S protectors? These may be a better fit…
Hi Subrata,
Please refer to the datasheet for the typical application. If you would like an EVM the bq40z50 has the bq2961 device on board.
Thanks
Miguel

Hi,
We have no plans at the moment for a different part specifically for LFP. If you want a 2S OVP device without cell balancing you can find the bq2947, bq2945xx, bq2961, bq2962 or bq7716 to see if any match your desired OVP.

Hi,
I suggest that you try to get in contact with your local TI sales office for this. If you don't have a TI sales office, then unfortunately you will only be able to work with the devices already released. In terms of OVP protectors we have a large…
Hi Justin,
I'm looking for the 3d model of the case for the bq40z50. The only 3d model on the TIDA-00883 page is for the BQ2961.
Is there a bxl file for the bq40z50 package (32VQFN)? I remember reading that if a 3d model wasn't available, TI would…
Hi Dustin,
Q2: D1 is the designer's choice. The requirement is to prevent damaging voltages from reaching the bq77915 or other electronic part in the design. The designer may not have significant transients in their system or may have other techniques…
