MC34164-3LP

The MC34164-3LP is a programmable supervisor circuit with a very specific application field and its unique working principles. Supervisory circuits are integrated circuits that have the capability to monitor different types of voltages, signals, and loads in a device. These circuits are used in various applications including power supplies and motor controlling systems. The MC34164-3LP is part of a family of family of Supervisors from On Semiconductor that provide a variety of features, depending on the model.

The MC34164-3LP is a single-microprocessor supervisor designed to monitor power-on/power-off reset, overvoltage, and undervoltage. This circuit is an adjustable version of the MC34164-3LP and provides the flexibility of adjusting the voltage detection levels. Its adjustable voltage detection feature is key to preventing dangerous situations like the overvoltage of a system\'s power supply. Since this supervisor is specifically designed for microcontroller systems, it is ideal for applications that require voltage and reset monitoring.

The MC34164-3LP includes an upper threshold voltage setting and a lower threshold voltage setting. These settings allow for up to five different voltage levels to be monitored. This specific supervisor also includes a power-on/power-off reset control, which is very useful in ensuring the system\'s reset pin is properly triggered. This reset control also helps to protect the system from the effects of over-voltage and provides additional protection from power surges.

The working principle of the MC34164-3LP is based on the hysteresis effect. This circuit uses a comparator which compares the voltage of the system to a reference voltage. When the voltage is higher than the reference, it initiates the reset control circuit which in turn triggers the reset pin. When the voltage goes below the reference voltage, the reset pin is deactivated. This way, the system can be reset even if the voltage of the power supply fluctuates, as the reset pin will be triggered when the voltage goes beyond the reference, and it will be deactivated when the voltage drops again.

The MC34164-3LP is a versatile and reliable supervisor that offers a great array of features to ensure safe system operation and prevent overvoltage. It is perfect for microcontroller applications and the adjustable voltage detection levels help ensure the system\'s reliable operation in power supplies, motor controlling systems and other applications. This circuit\'s hysteresis-based working principle ensures the system remains reset and protected, no matter how much the power supply voltage fluctuates.
