Working Principles

The MAX8211MSA/PR-T operates by comparing the voltage at the IN+ pin with the threshold voltage set using the SET pin. If the voltage at IN+ exceeds the threshold, the OUT pin is pulled low, indicating a high voltage condition. Conversely, if the voltage at IN+ falls below the threshold, the OUT pin remains high, indicating a low voltage condition.
