Working Principles

The MAX6717UKVDD3+T operates by comparing the input voltage with the threshold voltage set by the user using the THR pin. If the input voltage exceeds the threshold, the digital output (OUT) is pulled low. Conversely, if the input voltage falls below the threshold, the digital output is in a high-impedance state. The device continuously monitors the voltage and updates the output accordingly.
