BQ76907: BQ76907 Data Memory Voltage Gain computation

Part Number: BQ76907

Tool/software:

Dear TI Support Team,

I'm using BQ76907 5cell configuration trying to compute Cell gain.

Vcell mode = 0x05

Cell 1 Gain = 65535

Cell # Gain Delta = 0

Cell # Gain was calculated using following formula with 2 precise DC voltages(2.5V and 4.5V) to cell input and averaging multiple raw measurements in 16-bit counts obtained from the cell # voltage() command for each voltage

  2.5V raw  4.5 raw Gain Gain Delta
vcell1 13777 24649 12055.92  
vcell2 13761 24620 12070.36 14.432913
vcell3 13774 24640 12062.58 6.6570533
vcell4 13778 24660 12044.84 -11.078775
vcell5 13760 24613 12077.03 21.10592

1. Cell 4 and 5 Gain Delta = (Cell 4 Gain - Cell 1 Gain) OR (Cell 5 Gain - Cell 1 Gain)?

2. Cell 6 and 7 Gain Delta = (Cell 6 Gain - Cell 1 Gain) OR (Cell 7 Gain - Cell 1 Gain)?

3. In my application, Cell 4 and cell5 gain to be stored in which data memory address? Cell 5 and 7 or cell 4 and 5?
