The MAX6389XS31D1+T is a precision, low-power, single-channel voltage monitor from Maxim Integrated, designed to safeguard systems against undervoltage conditions. This device is part of Maxim's extensive family of microprocessor (µP) supervisory circuits that monitor power supplies in digital systems. It provides excellent reliability and accuracy for a wide range of applications.

Key Features

• Voltage Threshold: The MAX6389XS31D1+T monitors a preset voltage threshold of 3.1V, making it ideal for 3.3V power supply systems.
• Low Power Consumption: With its low quiescent current, this device is suitable for power-sensitive applications, extending battery life in portable devices.
• Package: The device comes in a compact, surface-mount SC70 package, which is ideal for space-constrained applications.
• Temperature Range: It operates over an industrial temperature range of -40°C to +125°C, ensuring reliability in harsh environments.
• Reset Output: The active-low reset output ensures that the connected microprocessor resets cleanly when the monitored voltage falls below the threshold.
• Reset Timeout: The device features an internally fixed reset timeout period, providing a predictable delay before the system reset is deasserted after the voltage returns to an acceptable level.

Applications

The MAX6389XS31D1+T is suitable for a variety of applications where voltage monitoring is critical. It is commonly used in:

• Portable/Battery-Powered Equipment
• Computers and Servers
