Working Principles

The TLC7733QDRG4 operates based on a voltage comparator principle. It compares the input voltage (VIN) with the threshold voltage (TH) set by the user. If the input voltage exceeds the threshold voltage, the output (OUT) is pulled low, indicating an overvoltage condition. Conversely, if the input voltage falls below the threshold voltage, the output remains high, indicating a normal voltage level.
