Description Early Warning Function

The additional sense comparator provides an early warning function: Any voltage (e.g. the input voltage) can be

monitored, an undervoltage condition is indicated by setting the comparator’s output to low. The use of an external

voltage divider makes this comparator very flexible in the application.
