Working Principles

The MAX6719AUTSVD3+T operates by comparing the input voltage (IN) with the threshold voltage (TH) set by the user. When the input voltage exceeds the threshold, the output (OUT) goes high, indicating that the voltage is above the desired level. Conversely, when the input voltage falls below the threshold, the output goes low, indicating that the voltage is below the desired level.
