Inputs
IN1–IN4
The IN1–IN4 voltage detectors monitor voltages from
1V to 5.5V in 20mV increments, or +0.5V to +3.05V in
10mV increments. Use the following equations to set
the threshold voltages for IN_:
for +1V to +5.5V range.
for +0.5V to +3.05V range.
where VTH is the desired threshold voltage and x is the
decimal code for the desired threshold (Table 6). For
the +1V to +5.5V range, x must equal 225 or less; oth-
erwise, the threshold exceeds the maximum operating
voltage of IN1–IN4 (Table 6). An overvoltage or under-
voltage failure on an IN_ input immediately shuts down
all the OUT_ outputs and generates a FAULT in the
master/slave condition.
