Other Parts Discussed in Thread: BQ79616
Hello,
I am using two BQ79656 in a stack configuration to make a 32S pack. This is an image of BQ79616 IC, but since the stack operation is the same I am showing this as a reference.
My question pertains to the red encirclement
In the schematic, the region includes the 16th cell of the base stack and the 17th cell on the stack cell (or CB0 pin on the stack device). I will refer to the CB0 pin of the stack device as SCB0. I need to know how to connect the SCB0 pin to the CB16 pin. Should the SCB0 pin be directly shorted to CB16, or is there another method? I am also unsure about the filtering capacitor of SCB0. Should it be connected to the stack device's ground or the capacitor ladder of the base device?
Is there documentation that will reference the stacking of the two devices?
