Product Overview: MAX6348UR40+T

The MAX6348UR40+T is a high-quality microprocessor (µP) supervisory circuit produced by Maxim Integrated. This compact, highly reliable component is designed to monitor power supplies in µP and digital systems, providing a significant safeguard against system failure due to unstable or failing power supplies. It is especially useful in systems that require a high level of data integrity and operational consistency.

The device ensures that the µP boots up in a known, stable state by providing a reset signal to the µP during power-up, power-down, and brownout conditions. The reset output remains operational with VCC as low as 1.2V, and the reset timeout period is externally adjustable with a capacitor, allowing designers to customize the reset deassertion delay as per their system requirements.

One of the key features of the MAX6348UR40+T is its low supply current of 1.2µA, which makes it ideal for portable battery-operated applications where power efficiency is paramount. The device operates over a wide voltage range, from 1.2V to 5.5V, and the reset threshold for this particular model is precisely factory-trimmed to 4.0V, making it suitable for use with 5V-powered systems.

The MAX6348UR40+T comes in a tiny SOT-23 package, which takes up minimal board space, thus contributing to the miniaturization of the end product. Additionally, it is specified for the extended industrial temperature range of -40°C to +85°C, which assures reliable operation under various environmental conditions.

This supervisory circuit is provided in tape and reel form, indicated by the “+T” suffix in its part number, facilitating its use in automated manufacturing processes. It is an essential component for system designers seeking to enhance the reliability and stability of their µP systems, particularly in applications such as portable devices, embedded systems, and other digital electronics that require consistent monitoring of the power supply integrity.

In summary, the MAX6348UR40+T from Maxim Integrated is a versatile, low-power µP supervisory circuit that provides critical protection against power supply variations, ensuring stable operation and system integrity across a range of applications.
