ON Semiconductor MC34164P-5G Microprocessor Supervisory Circuit

The ON Semiconductor MC34164P-5G is a precision microprocessor supervisory circuit designed to monitor the power supplies in microprocessor and digital systems. It provides a reliable method for ensuring that the system voltage remains within acceptable parameters, thus safeguarding the system from uncertain operation that might arise due to power fluctuations.

Key Features:

• Voltage Threshold: The MC34164P-5G has a preset threshold voltage of 4.63V, which is ideal for 5V-powered circuits. This ensures that the microprocessor is reset to a known state during power-up, power-down, and brown-out conditions.
• Reset Delay Time: It features a built-in delay time which provides a stable reset signal for an adequate period after the supply voltage exceeds the threshold level.
• Low Power Consumption: This device is optimized for low power consumption, making it suitable for use in power-sensitive applications.
• Temperature Range: It operates over a temperature range of -40°C to +85°C, providing reliable performance in a variety of environments and applications.
• Package: The MC34164P-5G comes in a PDIP-8 package, which is easy to integrate into a wide range of electronic systems.

Applications:

The ON Semiconductor MC34164P-5G is versatile and can be used in numerous applications including:

• Microprocessor systems
• Computers
• Controllers
• Intelligent instruments
• Portable/Battery-powered equipment

Product Description:

The MC34164P-5G is a microprocessor supervisory circuit that asserts a reset signal whenever the VCC supply voltage declines below a preset threshold, 4.63V. The reset signal remains asserted until VCC rises above the reset threshold and for an additional reset time delay, ensuring proper system reset. The device's power-on reset circuitry guarantees that the reset output is asserted upon power-up. This feature is crucial for systems that require a predictable start-up sequence. The device's low power consumption and wide operational temperature range make it an excellent choice for a broad spectrum of applications, from industrial to consumer electronics. The MC34164P-5G's reliability and performance are backed by ON Semiconductor's commitment to high-quality semiconductor solutions.
