Working Principles

The MAX6400BS22+T operates by comparing the input voltage (IN) with the threshold voltage. When the input voltage exceeds the threshold, the output (OUT) is pulled low. Conversely, when the input voltage falls below the threshold, the output remains high impedance. This behavior allows the device to provide a digital indication of the voltage level.
