Working Principles

The MAX6400BS29+T operates by comparing the input voltage with the threshold voltage set on the TH pin. When the input voltage exceeds the threshold, the digital output (OUT) is pulled low. Conversely, when the input voltage falls below the threshold, the output remains high impedance. This behavior allows the IC to monitor voltage levels and provide a digital indication of their status.
