Working Principles

The MAX6383XR40D1-T is designed to monitor the input voltage and generate a reset signal when the voltage falls below a user-defined threshold. The threshold voltage can be set by connecting the appropriate pin to the desired voltage level. When the input voltage drops below the threshold, the reset output becomes active-low, indicating a power failure or abnormal condition.
