NOTE: The inputs can monitor a voltage higher than V
DD
(max) with the use of an external resistor divider network.
Figure 21. Monitoring a Voltage Other Than V
DD
NOTE: In this case, OUTA is driven low when an undervoltage condition is detected at the 5-V rail and OUTB is driven low when an
overvoltage condition is detected at the 12-V rail.
