Tool/software:

I have designed and manufactured a 6s solar power management board with battery balancing using bq77915 and bq24560 Ic's. I am running into power issues with these two chips after testing the final product. I would love some schematic/design support with this board.

Hello Christian,

I am running into an issue when powering the board with a 24v supply at solar vin, the supply voltage drops to 0.3v. I assume the bq24650 is throwing a fault somewhere, but I'm unable to find an issue in the schematic. I can share the schematic with you, but would rather do it off of the public forum.
