Maxim Integrated MAX6420UK26+T Microprocessor Supervisory Circuit

The MAX6420UK26+T is a compact, highly reliable microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a trusted name in the development of advanced mixed-signal engineering solutions. This tiny device plays a critical role in monitoring the power supply and system health of microprocessor-based systems, ensuring that your electronic devices operate smoothly and reliably.

With its precision factory-set V<sub>CC reset threshold of 2.63V, the MAX6420UK26+T is perfect for managing power supplies and safeguarding system integrity in a wide array of applications. Its key features include a reset output that remains asserted for a minimum of 140ms after V<sub>CC has risen above the reset threshold, providing ample time for the system to stabilize.

This supervisory circuit is designed for low-power operation, drawing a minimal quiescent current of only 1.2µA, making it an ideal choice for portable and battery-powered applications where power efficiency is paramount. The MAX6420UK26+T comes in a compact SOT-23 package, which is perfect for space-constrained applications.

One of the standout features of the MAX6420UK26+T is its debounced manual reset input, which allows for a simple, user-initiated system reset. This is an invaluable feature for systems that require manual intervention to reinitialize operation without cycling the power.

The device also offers an active-low open-drain reset output, providing flexibility in interfacing with other components within the system. This versatility makes it suitable for a broad range of applications, from consumer electronics to industrial control systems.

In summary, the MAX6420UK26+T from Maxim Integrated is a sophisticated and reliable solution for microprocessor system management. Its low power consumption, precision voltage monitoring, and user-friendly features make it an essential component for ensuring the longevity and reliability of your electronic products.
