where VTH is the desired threshold voltage and x is the
decimal code for the desired threshold (Table 3).
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-
