Functional Features

Voltage Monitoring

MC34164P-5RAG monitors the input voltage (VIN) and compares it with the reference voltage (VREF). It provides an output signal indicating whether the input voltage is within the desired range or if it exceeds the preset thresholds.

Overvoltage and Undervoltage Protection

When the input voltage exceeds the upper threshold, the output goes low, indicating an overvoltage condition. Similarly, when the input voltage falls below the lower threshold, the output also goes low, indicating an undervoltage condition.

Adjustable Threshold Voltage

The threshold voltage can be adjusted using an external resistor divider network connected to the VREF pin. This allows customization of the voltage levels at which the monitoring and protection functions are triggered.

Hysteresis for Noise Immunity

MC34164P-5RAG incorporates hysteresis in its voltage monitoring circuitry, providing noise immunity by preventing rapid toggling of the output due to small voltage fluctuations around the threshold levels.
