Working Principles

MC33064P-5RAG operates based on a voltage comparator circuit. It compares the input voltage (VIN) with the reference voltage (VREF) set by the user. When the input voltage exceeds the threshold voltage, the output (OUT) is pulled low, indicating an overvoltage condition. Similarly, when the input voltage falls below the threshold voltage, the output is pulled low, indicating an undervoltage condition. The hysteresis feature prevents rapid toggling of the output near the threshold voltage, ensuring stable operation.
