Working Principles

The MAX6754UKLD3+T operates by continuously monitoring the voltage level at the IN pin. It compares this voltage with the user-programmed threshold voltage. If the input voltage exceeds the threshold, the OUT pin goes high, indicating that the voltage is above the desired level. Conversely, if the input voltage falls below the threshold, the OUT pin goes low.

The device utilizes an internal voltage reference and a comparator to perform the voltage monitoring function. The accuracy of the monitoring is ensured by the precise voltage reference and the low offset comparator.
