Working Principles

The MAX8213AESE/GG8 operates by comparing the input voltage (IN+) with a reference voltage (SET). When the input voltage falls below the threshold set by the SET pin, the output (OUT) is pulled low. This active-low signal can be used to trigger an alarm or initiate corrective actions in the monitored system.
