Maxim Integrated MAX6383XR31D2+T Microprocessor Reset Circuit

The MAX6383XR31D2+T from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of system reliability through its reset function, ensuring that the µP resets to a known state during power-up, power-down, or brown-out conditions.

This compact device is tailored for systems that require precision monitoring without the overhead of external components. The MAX6383XR31D2+T is available in a small, 3-pin SC70 package, making it ideal for space-constrained applications where board real estate is at a premium. Despite its diminutive size, it offers a robust set of features that make it a versatile choice for a wide range of applications.

One of the key features of the MAX6383XR31D2+T is its factory-set reset threshold voltage. The device triggers a reset when the VCC supply voltage falls below 3.1V, ensuring that the system has enough power to operate safely. The reset output remains asserted for a minimum reset timeout period of 140ms after VCC rises above the reset threshold, providing a predictable and controlled startup for the µP.

The device also boasts a low supply current of typically 1.2µA, making it an energy-efficient choice for portable and battery-operated applications. The MAX6383XR31D2+T operates over a wide temperature range of -40°C to +125°C, ensuring reliable performance across diverse environmental conditions.

For designers looking for a reset circuit that offers a balance of small size, precision, and low power consumption, the MAX6383XR31D2+T is an excellent choice. Its ease of integration, coupled with Maxim Integrated's reputation for high-quality semiconductor products, makes it a go-to solution for maintaining system integrity through power management.

Whether it's used in consumer electronics, industrial controllers, or automotive systems, the MAX6383XR31D2+T provides the essential protection needed to keep microprocessor-based systems running smoothly and reliably.
