Functional Features

• Monitors the supply voltage and generates a reset signal when it falls below a certain threshold.
• Provides a precision monitoring solution for microprocessors and other digital systems.
• Offers a low power consumption design, suitable for battery-powered applications.
• Includes a reset timeout feature to ensure proper system initialization.

Advantages

• Wide supply voltage range allows for versatile use in various electronic systems.
• Precision monitoring ensures reliable operation of microprocessors and digital circuits.
• Low quiescent current minimizes power consumption, extending battery life.
• Reset timeout feature prevents false resets during power fluctuations or noise.

Disadvantages

• Limited number of package options available.
• Reset threshold voltage is fixed and cannot be adjusted externally.

Working Principles

The MC34164LP operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the threshold level set by the THRES pin, the RESET output is activated, indicating a low voltage condition. The reset signal remains active until the supply voltage rises above the threshold level and the reset timeout period elapses.

The MC34164LP is commonly used in various applications where reliable voltage monitoring and system reset functionality are required. Some typical application fields include:

1. Microprocessor Systems
2. Embedded Systems
3. Power Management Circuits
4. Industrial Control Systems
5. Automotive Electronics
