Working Principles

The MAX6384LT28D2+T is designed to monitor the supply voltage of a system and generate a reset signal when the voltage falls below a certain threshold. It utilizes an internal voltage reference and comparator to compare the monitored voltage with the selected threshold voltage. When the voltage drops below the threshold, the reset output is activated, indicating a low-voltage condition. The reset remains active until the voltage rises above the threshold or a timeout period elapses.
