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 output
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.
If the calculated error is greater than zero, then the
V TRIPx must first be “reset”, and then programmed to
the a value equal to the previously set V TRIPx minus
the calculated error. If it is the case that the error is
less than zero, then the V TRIPx must be programmed
to a value equal to the previously set V TRIPx plus the
absolute value of the calculated error.
Continuing the previous example, we see that the cal-
culated error was 0.09V. Since this is greater than
zero, we must first “reset” the V TRIP2 threshold, then
apply a voltage equal to the last previously pro-
grammed voltage, minus the last previously calculated
error. Therefore, we must apply V TRIP2 = 2.91 V to pin
V2MON and execute the programming sequence (See
"Setting a Higher V TRIPx Voltage (x = 1,2,3)").
Using this process, the desired accuracy for a particu-
lar V TRIPx threshold may be attained using a succes-
sive number of iterations.
