Other Parts Discussed in Thread: TIDA-00108
Hello,
I have used the bq2947 part successfully on a 4s pack as a secondary over-voltage protection. I am in the process of developing a 7s pack but didn't see any components that perform this function on a 7s. I'm interested in using 2 of these parts, one for the lower 4 cells in the stack w/ the PWR Pad being the bottom of the stack, and another one for the upper 3 cells of the stack w/ the PWR pad being cell 4. Would you see any problem w/ this implementation? If so, how would you suggest tying the OUT pins of the two parts to drive the same fuse blowing circuit?
Thanks,
Mike
