Working Principles

The MAX6385XS19D2-T operates by comparing the input voltage with the threshold voltage set by the user using the TH pin. When the input voltage exceeds the threshold, the output pin (OUT) is pulled low. Conversely, when the input voltage falls below the threshold, the output pin is in a high-impedance state. The device continuously monitors the voltage level and provides an accurate digital output accordingly.
