Working Principles

The MAX6380XR44-T operates by continuously monitoring the supply voltage using an internal voltage reference and a comparator. When the voltage falls below or exceeds the selected threshold, the reset output is activated, indicating a fault condition. The reset remains active until the voltage returns within the acceptable range or a manual reset signal is received. The reset timeout period can be adjusted using an external capacitor.
