Working Principles

The MAX6383XR16D3+T operates by comparing the input voltage with the selected threshold voltage. When the input voltage falls below the threshold, the reset output is activated, indicating a power failure or abnormal voltage condition. Conversely, when the input voltage exceeds the threshold, the reset output is deactivated. The manual reset input allows for external control over the reset function.
