Maxim Integrated MAX6382XR28D3+T Microprocessor Reset Circuit

The MAX6382XR28D3+T is a high-quality microprocessor (μP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides a reliable method to ensure that microprocessors and other sensitive digital systems reset to a known state during power-up, power-down, or brownout conditions. This small, yet powerful device is essential for maintaining the integrity of system operations and preventing data corruption.

Encased in a compact SC-70 package, the MAX6382XR28D3+T offers a fixed reset threshold voltage of 2.8V, suitable for 3V to 3.3V powered circuits. The reset output stage of this device is active-low and open-drain, which allows for the connection of a pull-up resistor to a voltage higher than VCC, if necessary. This flexibility makes it compatible with a wide variety of digital systems.

One of the key features of the MAX6382XR28D3+T is its precision factory-set reset threshold, which ensures accurate monitoring without the need for external components. The device also boasts a low supply current of just 1.1μA, which is ideal for power-sensitive applications. Additionally, the reset timeout period is 210ms (min), providing a sufficient delay to ensure proper system reset.

The MAX6382XR28D3+T is designed to be robust, with the ability to handle transient faults and to operate over a wide temperature range of -40°C to +125°C. This makes it suitable for use in harsh environments and in a variety of industrial applications. The device is also offered in a tape-and-reel format, denoted by the '+T' suffix, which facilitates automated assembly processes, making it a convenient choice for high-volume production.

Overall, the MAX6382XR28D3+T from Maxim Integrated is a reliable and efficient solution for system designers looking to enhance the operational stability of their digital systems. Its low power consumption, precision voltage monitoring, and compact form factor make it an excellent choice for a wide range of applications in computing, consumer electronics, and industrial control systems.
