Working Principles

ADM809JARTZ-REEL7 operates based on a voltage comparator circuit. It compares the monitored supply voltage with the preset threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, indicating a low-voltage condition. The reset signal remains active until the supply voltage rises above the threshold or a manual reset is triggered.
