(Note 5)
DSG = CHG = low
Note 1: Applies to the differential voltage measured on any cell.
Note 2: DSG is internally clamped to a maximum of 20V to protect the external MOSFET (VGS).
Note 3: Guaranteed by design.
Note 4: The input bias matching between cells is measured with a 4V voltage between cells.
Note 5: At least one cell is <VUV.
Note 6: Specifications to -40°C are guaranteed by design, not production tested.
