After applying the test voltage to the voltage monitor
input pin, the test voltage can be decreased (either in
discrete steps, or continuously) until the output of the
voltage monitor circuit changes state. At this point, the
error between the actual / measured, and desired
threshold levels is calculated.
For example, the desired threshold for V
TRIP2
is set to
3.0 V, and a test voltage of 3.4 V was applied to the input
pin V2MON (after applying power to V
CC
). The input volt-
age is decreased, and found to trip the associated out-
put level of pin V2FAIL from a LOW to a HIGH, when
V2MON reaches 3.09 V. From this, it can be calculated
that the programming error is 3.09 - 3.0 = 0.09 V.
If the error between the desired and measured V
TRIPx
is
less than the maximum desired error, then the program-
ming process may be terminated. If however, the error is
greater than the maximum desired error, then another
iteration of the V
TRIPx
programming sequence can be
performed (using the calculated error) in order to further
increase the accuracy of the threshold voltage.
