Working Principles

APX803S-40SR-7 operates by comparing the input voltage with a fixed threshold voltage. When the input voltage drops below the threshold, the reset output becomes active-low, indicating a voltage fault condition. The reset signal remains active until the input voltage rises above the threshold level.
