Maxim Integrated MAX6326XR31+T Microprocessor Supervisory Circuits

The MAX6326XR31+T is a highly reliable microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant level of system reliability through its reset and monitoring functions, ensuring that the µP boots up in a known state every time. This device is particularly useful in applications where precise voltage monitoring is critical for the performance and safety of the system.

This supervisory circuit offers several key features that make it ideal for a wide range of applications, including portable devices, computers, controllers, and intelligent instruments. The MAX6326XR31+T provides a factory-trimmed reset threshold voltage of 3.1V, which is suitable for 3.3V-powered systems. The reset output remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, ensuring a proper system reset during power-up, power-down, or brownout conditions.

One of the advantages of the MAX6326XR31+T is its low power consumption, with a typical supply current of only 1.2µA, making it an excellent choice for power-sensitive applications. Its compact form factor is another benefit, as it comes in a small SOT-23 package, which is ideal for space-constrained designs.

The device also features a debounced manual reset input, which allows for a manual system reset. This input can be triggered with an external push-button or logic signal, providing an additional layer of control to the user or system operator. The MAX6326XR31+T operates over a wide temperature range of -40°C to +125°C, ensuring reliable performance across various environmental conditions.

Overall, the Maxim Integrated MAX6326XR31+T is a robust and precise supervisory circuit that offers a simple and effective solution for system monitoring and reset functions. Its low power consumption, small size, and manual reset feature make it a versatile component for enhancing system stability and reliability.
