High-Voltage Input (IN1)
IN1 offers threshold voltages of +2.5V to +13.2V in
50mV increments, or +1.25V to +7.625V in 25mV incre-
ments. Use the following equations to set the threshold
voltages for IN1:
where VTH is the desired threshold voltage and x is the
decimal code for the desired threshold (Table 2). For
the +2.5V to +13.2V range, x must equal 214 or less,
otherwise the threshold exceeds the maximum operat-
ing voltage of IN1.
IN2
IN2 offers thresholds from +2.5V to +5.5V in 50mV
increments, or +1.25V to +3.05V in 25mV increments.
Use the following equations to set the threshold volt-
ages for IN2:
where VTH is the desired threshold voltage and x is the
decimal code for the desired threshold (Table 3).
For the +2.5V to +5.5V range, x must equal 60 or less,
otherwise the threshold exceeds the maximum operat-
ing voltage of IN2. For the +1V to +3.05V range, x must
equal 72 or less.
IN3–IN6
IN3–IN6 offer positive voltage detectors monitor volt-
ages from +1V to +5.5V in 20mV increments, or +0.5V
to +3.05V in 10mV increments. Use the following equa-
tions to set the threshold voltages for IN_:
where VTH is the desired threshold voltage and x is the
decimal code for the desired threshold (Table 4). For
the +1V to +5.5V range, x must equal 225 or less, oth-
erwise the threshold exceeds the maximum operating
voltage of IN3–IN6.
