Working Principles

The MAX6720UTLTD3+T is a voltage detector that monitors the input voltage and provides a reset signal when it falls below a certain threshold. It operates based on a precision reference voltage and a comparator circuit. When the input voltage drops below the selected threshold, the reset output becomes active-low, indicating a power failure or low voltage condition.
