Working Principles

MC33064DM-TR operates by comparing the input voltage (VIN) with a reference voltage (VREF). When the input voltage exceeds the threshold voltage set by the THRESH pin, the output (OUT) is pulled low, indicating an overvoltage condition. Conversely, if the input voltage falls below the threshold voltage, the output is released, indicating an undervoltage condition.

The RESET pin provides a power-on reset function, ensuring that the output remains low during power-up until the input voltage stabilizes within the acceptable range.
