Product Overview: MAX6314US43D2+ by Maxim Integrated

The MAX6314US43D2+ is a high-quality microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a renowned leader in the development of innovative analog and mixed-signal products. This supervisory circuit is engineered to monitor power supplies in µP and digital systems, providing a significant level of system reliability and precision that is crucial for maintaining the integrity of the system's operation.

This particular model, the MAX6314US43D2+, features a fixed-sense threshold voltage of 4.3V, making it ideal for 5V-powered systems. Its primary function is to assert a reset signal whenever the VCC supply voltage falls below the preset threshold, ensuring that the µP resets cleanly during power-up, power-down, and brown-out conditions. The reset output remains asserted for a minimum of 140ms after VCC rises above the reset threshold, providing ample time for the system to stabilize.

The compact and efficient design of the MAX6314US43D2+ is encapsulated in an SOT-143 package, which not only saves space but also offers reduced power consumption. This device consumes a low supply current of only 1µA, making it an energy-efficient choice for portable and battery-operated applications.

With its built-in features, the MAX6314US43D2+ provides a robust set of protections for your system. These include:

• Immunity to short VCC transients
• No external components required
• Debounced manual reset input
• Ability to assert reset with a pushbutton
• Temperature range of -40°C to +85°C, ensuring reliable operation in various environmental conditions

Whether you're designing consumer electronics, computers, controllers, or any other sensitive digital system, the MAX6314US43D2+ offers the reliability and performance that engineers have come to expect from Maxim Integrated products.

By integrating the MAX6314US43D2+ into your design, you can enhance the overall stability and reliability of your system, safeguarding against unexpected power-downs and ensuring a smoother user experience.
