Maxim Integrated's MAX6314US44D2+T Microprocessor Reset Circuit

Maxim Integrated's MAX6314US44D2+T is a highly reliable, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of system reliability through its ability to reset a system upon detection of an out-of-tolerance power supply condition, ensuring your system starts in a known state every time.

The MAX6314US44D2+T is an ideal solution for managing system resets with its preset 4.4V voltage threshold, which is suitable for a wide range of applications. It is tailored to maintain system integrity by monitoring the VCC for under-voltage conditions. When VCC falls below the reset voltage threshold, the RESET output is asserted to signal the processor to reset, thereby preventing code execution errors during low voltage conditions.

This device comes in a compact, 4-pin SOT-143 package, making it perfect for space-constrained applications. The suffix 'T' in its part number indicates that it is provided in tape and reel packaging, which is convenient for automated manufacturing processes. The MAX6314 series is characterized for operation over a temperature range of -40°C to +85°C, allowing it to perform reliably in a variety of harsh environments.

Key features of the MAX6314US44D2+T include:

• Low supply current of 1µA (typical), which is ideal for battery-powered and portable applications.
• Guaranteed reset valid to VCC = 1V, ensuring proper system reset even during low voltage conditions.
• No external components are required, providing a simple and cost-effective design solution.
• Immunity to short VCC transients, protecting the system from spurious resets.

Overall, the MAX6314US44D2+T by Maxim Integrated is a robust and reliable choice for designers who need to safeguard their microprocessor systems against power supply instabilities. Its ease of integration and low power consumption make it an efficient choice for maintaining system stability across a variety of electronic applications.
