Hi Sir,
The datasheet is show the Pin 18 CELL_BATPRESZ also sets SYSOVP threshold to 5 V for 1-cell,
12 V for 2-cell and 18.5 V for 3-cell.
So Pin18=5V=1Cell, Pin18=12V=2cell , Pin18=18.5V=3cll, CELL_BATPRESZ Absolute Maximum is 7V.
But the EVM is used the VDDA=REGN=6V R20/R21/R24/R28 Partial pressure,
So Pin18=1.2V=1Cell, Pin18=2.72V=2cell, Pin=3.85V=3cell, Pin18=4.22V=4Cell
I am not sure which one is right, May I double confirm with you?
