Maxim Integrated MAX6375XR31+T Voltage Supervisor

The Maxim Integrated MAX6375XR31+T is a precision, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring.

This compact supervisory IC ensures that the µP and other devices receive a clean reset and power-up in a proper manner. It achieves this by monitoring the VCC voltage and asserting a reset signal whenever VCC drops below the factory-set reset threshold voltage. The reset signal remains asserted for a preset timeout period after VCC rises above the reset threshold, ensuring system stability.

Key features of the MAX6375XR31+T include:

• Factory-Set Reset Threshold: The reset threshold voltage is preset at 3.1V, which is suitable for operation with standard 3.3V power supplies, providing a tight accuracy necessary for reliable operation.
• Low Power Consumption: With its low supply current of 1.6µA (typical), it is ideal for portable and battery-powered applications where power efficiency is crucial.
• Manual Reset Input: A manual reset input allows the user to trigger a system reset with an external pushbutton or logic signal.
• Immune to Short VCC Transients: The device includes a built-in glitch immunity to ensure that the output remains in the correct state during brief power interruptions or fluctuations.
• Power-Supply Transient Immunity: No external components are required for transient immunity, simplifying design and reducing PCB space requirements.
• Compact SOT-23 Packaging: The MAX6375XR31+T comes in a small, 3-pin SOT-23 package, making it suitable for space-constrained applications.

The MAX6375XR31+T is a versatile component that can be used in a variety of applications, including microprocessor-based systems, computers, controllers, and intelligent instruments. Its robust design and precision monitoring capabilities make it an essential part of any system where reliable operation is critical.

With Maxim Integrated's reputation for high-quality and high-performance integrated circuits, the MAX6375XR31+T is an excellent choice for designers looking to enhance system reliability and performance with minimal additional cost and complexity.
