Maxim Integrated MAX6417UK+ Microprocessor Supervisory Circuit

The Maxim Integrated MAX6417UK+ is a compact, highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant line of defense against power supply failures, ensuring that your systems are running within their specified voltage ranges and enhancing overall stability and performance.

This supervisory circuit offers a variety of features that make it an essential component for any system requiring robust power management. The MAX6417UK+ is engineered to maintain system integrity through features such as reset output, which ensures that the µP resets cleanly during power-up, power-down, and brownout conditions. The reset signal remains asserted for a minimum timeout period after VCC has risen above the reset threshold level, providing a reliable startup for the µP.

One of the key features of the MAX6417UK+ is its precision monitoring of multiple supply voltages without the need for external components. This is particularly useful in systems where space is at a premium and reliability cannot be compromised. The device's low supply current of 1.6µA (typ) makes it an energy-efficient choice for portable and battery-powered applications.

The MAX6417UK+ also offers a manual reset input, which provides a hardware override of the reset output. This allows for an external signal to initiate a system reset, offering additional control and safety mechanisms for the user. Furthermore, the device comes in a small SOT23 package, which is ideal for space-constrained applications while still providing the robustness expected of Maxim Integrated products.

With a wide operating voltage range from 1.2V to 5.5V, the MAX6417UK+ is versatile and can be used in a variety of applications, from consumer electronics to industrial systems. Its threshold voltage is factory-set, which eliminates the need for external resistors and ensures consistent performance across multiple devices.

In summary, the Maxim Integrated MAX6417UK+ is a reliable, energy-efficient supervisory circuit that provides critical monitoring and control to ensure the proper functioning of microprocessor-based systems. Its compact form factor and robust feature set make it an excellent choice for a wide range of applications where precision and reliability are paramount.
