Maxim Integrated MAX6804US31D3-T Microprocessor Reset Circuit

The Maxim Integrated MAX6804US31D3-T is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of protection for your system by ensuring a proper reset signal to the µP during power-up, power-down, and brown-out conditions. The compact SOT-143 package makes it suitable for space-constrained applications, while its precision voltage monitoring capability ensures systems operate within their designated voltage thresholds.

This device is specifically crafted to maintain system integrity by monitoring the supply voltage and asserting a reset if it detects a voltage that is out of the acceptable range. The MAX6804US31D3-T has a preset threshold voltage of 3.1V, making it ideal for 3.3V-powered systems that require a tight monitoring threshold to ensure proper operation.

Key Features

• Precision Voltage Monitoring: The MAX6804US31D3-T offers precise monitoring of the 3.1V threshold, which is crucial for systems that operate close to this supply voltage.
• Low Power Consumption: With its low power consumption, this device is an excellent choice for battery-operated and portable applications where power efficiency is paramount.
• Manual Reset Input: The inclusion of a manual reset input provides an additional layer of control, allowing the system to be reset externally if required.
• Reset Timeout: It features an internally set timeout period that ensures the reset output remains valid for a sufficient duration after the supply voltage returns to an acceptable level.
• High Reset Output: The device can output a reset signal in both push-pull and open-drain configurations, depending on the specific needs of the application.

Designed for use in computers, controllers, intelligent instruments, and critical µP power monitoring, the MAX6804US31D3-T is a versatile component that enhances the reliability and stability of electronic systems. Its robust feature set, including the ability to operate over a wide temperature range, makes it suitable for a broad array of applications in the industrial, communication, and consumer electronics sectors.

By integrating the MAX6804US31D3-T into your system, you can ensure that your µP resets cleanly and your system maintains consistent performance, even under fluctuating power conditions. Maxim Integrated's commitment to quality means that you can rely on this reset circuit to safeguard your valuable systems.
