V3 monitoring
The X9522 asserts the V3RO output HIGH if the volt-
age V3 exceeds the corresponding V
TRIP3
threshold
(See Figure 14). The bit V3OS in the CONSTAT regis-
ter is then set to a “0” (assuming that it has been set to
“1” after system initilization).
The V3RO output may remain active HIGH with Vcc
down to 1V.
V
TRIPX
THRESHOLDS (X = 2,3)
The X9522 is shipped with pre-programmed threshold
(V
TRIPx
) voltages. In applications where the required
thresholds are different from the default values, or if a
higher precision / tolerance is required, the X9522 trip
points may be adjusted by the user, using the steps
detailed below.
Setting a V
TRIPx
Voltage (x = 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 neces-
sary to “reset” the V
TRIPx
voltage before setting the
new value.
