Working Principles

The MAX6363LUT26+T operates by comparing the input voltage with the threshold voltage set by the user. When the input voltage exceeds the threshold voltage, the digital output (OUT pin) is pulled low. Conversely, when the input voltage falls below the threshold, the output remains high impedance. The device continuously monitors the voltage level and updates the output accordingly.
