NBEN—Negative Blanking Enable. A value of 1 enables blanking of negative current values up to 25μV. A value of
0 disables blanking of negative currents. The power-up default of NBEN = 0.
UVEN—Undervoltage Enable. A value of 1 allows the DS2784 to enter Sleep mode when the voltage register value
is less than V
and DQ is stable at either logic level for t
. A value of 0 disables transitions to Sleep mode in an
