Maxim Integrated MAX6721UTYHD3-T Microprocessor Supervisory Circuit

The MAX6721UTYHD3-T from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to maintain system integrity in the face of power fluctuations and other conditions that could compromise the performance and safety of microprocessor systems. This component is particularly well-suited for portable and battery-powered applications due to its low power consumption and compact SOT23-6 package.

This supervisory circuit provides several key features that make it an essential component for system management:

• Reset Output: The MAX6721UTYHD3-T generates a reset signal whenever the VCC supply voltage falls below the factory-set reset threshold, ensuring the µP starts up in a known state. The reset signal remains asserted for a minimum reset timeout period after VCC has risen above the reset threshold, providing a stable environment for the µP to initialize.
• Manual Reset Input: This feature allows for a manual reset, enabling system designers to incorporate a user-accessible reset function or to initiate a reset from another part of the system.
• Low Power Consumption: With its low supply current, this device is optimized for power-sensitive applications, helping to extend battery life and reduce energy costs.
• Factory-Set Reset Thresholds: The reset thresholds are factory set and available in a variety of options to match specific system voltage requirements, providing flexibility in system design.
• High Accuracy: The MAX6721UTYHD3-T offers high threshold accuracy, ensuring reliable operation under various conditions and across temperature variations.
• Immune to Short VCC Transients: The device features a built-in glitch immunity to ensure that short duration transients on the VCC line do not result in a false reset, maintaining system stability.

Maxim Integrated's MAX6721UTYHD3-T is designed with the rigors of modern electronic systems in mind, providing a robust set of features that enhance the reliability and performance of microprocessor-based systems. Whether it's for consumer electronics, industrial controls, or portable devices, this supervisory circuit is an excellent choice for maintaining the integrity of your system.

With its precision monitoring and control of system voltages, the MAX6721UTYHD3-T is an integral component for any design requiring a high degree of reliability and operational stability.
