Maxim Integrated MAX6719AUTSUD3 Microprocessor Supervisory Circuits

The Maxim Integrated MAX6719AUTSUD3 is a highly reliable microprocessor (µP) supervisory circuit designed to maintain system integrity during power fluctuations and other conditions that could compromise the performance and reliability of electronic systems. This compact and efficient device is perfect for use in a wide range of applications, including portable devices, computers, controllers, and intelligent instruments, to name a few.

Designed with precision in mind, the MAX6719AUTSUD3 offers a variety of features that make it an essential component for any system requiring robust monitoring and control. It provides a watchdog timer, manual reset capability, and a reset output that remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold. This ensures that the µP has sufficient time to initialize and stabilize before commencing operation.

The device operates over a wide supply voltage range of 1.1V to 5.5V, making it versatile for various digital systems. Its low supply current of 7.5µA (typical) is particularly beneficial for battery-powered applications where power conservation is critical. The MAX6719AUTSUD3 comes in a compact, space-saving 6-pin SOT23 package, which is ideal for systems where board space is at a premium.

Key features of the Maxim Integrated MAX6719AUTSUD3 include:

• Adjustable reset threshold voltages to accommodate different µP and system voltage requirements.
• Debounced manual reset input, allowing for a reliable system reset.
• Watchdog timer to monitor system operation and initiate a system reset if necessary.
• Low quiescent current, contributing to energy efficiency in portable applications.
• Guaranteed reset output valid down to V_CC = 1.1V.
• Immune to short V_CC transients, providing stable operation through power glitches.

With its combination of features, the MAX6719AUTSUD3 from Maxim Integrated is an excellent choice for designers looking to enhance the reliability and performance of their systems. Its ease of integration and comprehensive functionality ensure that it can meet the demands of even the most challenging applications.
