Maxim Integrated MAX6804US29D3+T Microprocessor Reset Circuit

The MAX6804US29D3+T from Maxim Integrated is a high-quality microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +2.5V, +3V, +3.3V, and +5V-powered circuits.

This compact device is particularly well-suited for portable and space-constrained applications, thanks to its small SOT23 package. The MAX6804US29D3+T offers a precise factory-set reset threshold voltage, ensuring that your microprocessor system resets cleanly during power-up, power-down, and brown-out conditions.

Key Features:

• Reset Threshold Voltage: This component has a preset reset threshold voltage of 2.93V, which is ideal for systems operating around the 3V range.
• Reset Output: The MAX6804 provides an active-low reset signal, ensuring compatibility with a wide range of microprocessors and digital systems.
• Low Power Consumption: With its low supply current of only 1µA (typical), it is an excellent choice for battery-operated devices, contributing to extended battery life.
• Immune to Short Vcc Transients: The device is designed to ignore fast transients on the Vcc line, which helps to prevent false resets and system malfunctions.
• High-temperature Operation: The MAX6804US29D3+T can operate over a wide temperature range, making it suitable for industrial applications.
