Maxim Integrated MAX6747KA23+T Microprocessor Supervisory Circuits

The MAX6747KA23+T from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to maintain system integrity by monitoring the power supply voltage levels in digital systems. This component ensures that the microprocessor and associated circuitry operate within specified power supply limits, providing an extra layer of protection against unpredictable system behavior or data loss due to power fluctuations.

With its compact SOT-23 package, the MAX6747KA23+T is an ideal choice for space-constrained applications. It offers a precise factory-set reset threshold voltage of 2.32V, which is suitable for monitoring 2.5V power supplies. The reset output is available in both active-low and active-high configurations, making it versatile for different system requirements.

This supervisory circuit boasts a low supply current of only 7.5µA, making it an energy-efficient solution for portable and battery-powered devices. The reset timeout period is externally adjustable, allowing designers to customize the reset deassertion delay according to specific system needs. This feature helps prevent microprocessor reset signals from being falsely triggered by transient glitches on the power supply line.

The MAX6747KA23+T also includes a manual reset input, which provides a means to initiate a system reset manually. This is particularly useful for system maintenance or during debugging processes. The device's robust design ensures that it can operate over a wide temperature range of -40°C to +125°C, making it suitable for use in harsh environments.

Overall, the MAX6747KA23+T is a versatile, reliable, and energy-efficient solution for system voltage monitoring and control. Its precise voltage threshold, low power consumption, and adjustable reset timeout make it a valuable component for a wide range of applications, from consumer electronics to industrial control systems. With Maxim Integrated's reputation for quality, this supervisory circuit is a dependable choice for safeguarding your microprocessor-based systems.
