Maxim Integrated MAX6414UK31+T Microprocessor Reset Circuit

The MAX6414UK31+T is a sophisticated 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 and accuracy required in critical electronic applications. This device ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions.

Featuring a factory-set reset threshold voltage of 3.08V, the MAX6414UK31+T offers a precise monitoring solution for systems operating at 3.3V power supply levels. The reset output is guaranteed to remain in the active state for at least 140ms (minimum) after V_CC has risen above the reset threshold level, providing ample time for the system to stabilize.

The compact SOT23-5 package of the MAX6414UK31+T makes it an ideal choice for space-constrained applications. Its small footprint is complemented by its low supply current of only 6µA (typical), which makes it an energy-efficient option for portable and battery-operated devices. The device operates over a wide temperature range of -40°C to +125°C, ensuring reliable performance in diverse environmental conditions.

One of the key features of the MAX6414UK31+T is its ability to provide a debounced manual reset input. This allows for a manual override of the automatic reset, giving system designers and end-users an additional layer of control. Additionally, the device is designed with an open-drain reset output, which facilitates wired-OR connections for greater flexibility in system design.

Overall, the MAX6414UK31+T from Maxim Integrated is a robust and reliable solution for system monitoring. Its precision voltage monitoring, low power consumption, compact size, and additional features like manual reset input make it a versatile component suitable for a wide range of applications in computing, consumer electronics, networking, and telecommunications.

By integrating the MAX6414UK31+T into their designs, engineers can enhance system reliability, prevent data corruption, and ensure a smooth operation through all stages of power cycling, contributing to the creation of high-quality, dependable electronic products.
