V2MON Monitoring
The X4023x asserts the V2FAIL output HIGH if the
voltage V2MON exceeds the corresponding V
TRIP2
threshold (See Figure 21). The bit V2FS in the CR reg-
ister is then set to a “0” (assuming that it has been set
to “1” after system initialization).
The V2FAIL output may remain active HIGH with V
CC
down to 1V. (See Figure 21)
V3MON Monitoring
The X4023x asserts the V3FAIL output HIGH if the
voltage V3MON exceeds the corresponding V
TRIP3
threshold (See Figure 21). The bit V3FS in the CR reg-
ister is then set to a “0” (assuming that it has been set
to “1” after system initialization).
The V3FAIL output may remain active HIGH with V
CC
down to 1V. V
TRIPx
Thresholds (x = 1,2,3)
The X4023x is shipped with pre-programmed thresh-
old (V
TRIPx
) voltages. In applications where the
required thresholds are different from the default val-
ues, or if a higher precision / tolerance is required, the
X4023x trip points may be adjusted by the user, using
the steps detailed below.
Setting a V
TRIPx
Voltage (x = 1,2,3)
There are two procedures used to set the threshold
voltages (V
TRIPx
), depending if the threshold voltage to
be stored is higher or lower than the present value. For
example, if the present V
TRIPx
is 2.9 V and the new
V
TRIPx
is 3.2 V, the new voltage can be stored directly
into the V
TRIPx
cell. If however, the new setting is to be
lower than the present setting, then it is necessary to
“reset” the V
TRIPx
voltage before setting the new value.
