Tool/software:
Dear experts,
In my application case, there is negative cell voltage indeed.
for instance, A point = -1V, B point = -2V, C point = -3V, D point = -4V, etc. BQ79616 is powered externally.
in this case, BQ79616 is able to measure the negative cell voltage? The datasheet has statement like below,
it seems workable for n>=2 to 16, VCn - NVn-1 > = -1.
But it seems not, VC1 - VC0 must > 0, VCn to AVSS > = 3V.
then how can we understand the -1V voltage measurement in datasheet? it seems that CELL1 need be always positve for negative voltage measurement. why?
Cheers.
Alex
