Maxim Integrated MAX6314US44D2 Microprocessor Reset Circuit

The MAX6314US44D2 is a compact, highly reliable microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant function in ensuring that systems operate correctly by resetting a µP during power-up, power-down, and brownout conditions. The device's versatility makes it suitable for a broad range of applications, including computers, controllers, and intelligent instruments.

Key Features

• Power Supply Monitoring: The MAX6314US44D2 ensures that the µP is only operational when the power supply is within an acceptable range. It monitors the supply voltage and keeps the µP in reset mode until stable power is assured.
• Factory-Trimmed Reset Threshold: The reset threshold voltage is preset at the factory to 4.4V, which is ideal for 5V-powered systems, ensuring accurate monitoring without the need for external components.
• Manual Reset Input: A manual reset input is provided, allowing for a reset to be triggered with an external button or signal for system diagnostics or firmware updates.
• Low Power Consumption: With its low power consumption, the device is an excellent choice for portable and battery-operated equipment, helping to extend battery life and reduce overall power usage.
• High Reset Output Stage Options: The MAX6314US44D2 offers both push-pull and open-drain reset output stage configurations to accommodate different system requirements.
• Compact SOT-143 Package: The device comes in a small, surface-mount SOT-143 package, making it easy to integrate into space-constrained designs.

Applications

The MAX6314US44D2 is designed for use in a variety of applications where reliable system operation is critical. It is particularly useful in:

• Portable Devices
• Embedded Systems
• Microprocessor-based Equipment
• Industrial Controllers
• Automotive Systems

With its precision power-supply monitoring and versatile features, the MAX6314US44D2 from Maxim Integrated is an essential component for maintaining system integrity and preventing data corruption due to unexpected power failures or anomalies.
