Current Programming
There are three different over-temp thresholds
for each AS273. The detector senses the amount
of current being shunted through the 2.5 V refer-
ence of pin 1 and programs an over-temp thresh-
old based on the magnitude of that current. Fig-
ure 10 illustrates the ranges of reference shunt
current, I
REF, associated with each of the three
over-temp thresholds, OT1, OT2 and OT3.
