The MAX6327UR31+T is a precision, low-power, low-dropout voltage microprocessor (µP) supervisory circuit designed by Maxim Integrated to ensure reliable operation of microprocessor-based systems. This component is particularly suitable for battery-powered electronics where low quiescent current and high accuracy are essential.

Key Features

• Voltage Monitoring: The MAX6327UR31+T offers a preset reset threshold voltage of 3.1V, which is ideal for 3.3V-powered systems, ensuring that the µP is reset to a known state during power-up, power-down, or brownout conditions.
• Low Power Consumption: With a low supply current of only 1.2µA, this supervisory circuit is an excellent choice for portable and battery-operated devices where power efficiency is a priority.
• High Accuracy: It provides a tight reset threshold accuracy of ±2% over the entire temperature range of -40°C to +85°C, which is critical for reliable system operation.
• Manual Reset Input: An additional feature includes a debounced manual reset input, allowing for a forced reset when necessary.
• Compact Package: The device is available in a compact SOT-23 package, which is ideal for space-constrained applications.
• Immune to Short V-Drop Events: The MAX6327UR31+T is designed with a 140ms (min) reset timeout period, ensuring that short duration voltage drops do not cause false resets.

Applications

The MAX6327UR31+T is versatile and can be used in a wide range of applications, including:

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Embedded Systems
• Industrial Equipment
• Data Storage Systems
