MAX6467US31D3

Overview

The MAX6467US31D3 is a microprocessor supervisory reset circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single power supply voltage and asserts an active-low, open-drain reset signal when the input drops below a fixed threshold of 3.075V. The device features a manual reset function and operates within a supply range of 1.8V to 5.5V. It is housed in a compact SOT-143-4 package and supports industrial temperature ranges from -40°C to +125°C.

Feature Summary

• Monitors single power-supply voltages with a fixed threshold
• Asserts active-low reset output via open-drain configuration
• Includes edge-triggered, one-shot manual reset capability

Applications

• Microprocessor system supervision
• Power supply monitoring for embedded controllers
• Battery-operated equipment requiring low quiescent current

Procurement Notes

Verify the specific suffix 'D3' against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required 3.075V threshold and SOT-143-4 form factor for your design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit parts.

Selection Notes

Select this component when a fixed threshold supervisor is needed for single-rail systems. It is suitable for applications requiring manual reset control alongside automatic power-fail detection. Consider the SOT-143-4 footprint constraints and the active-low open-drain output requirements during PCB layout.

Part Context

This part belongs to the MAX6467 series of microprocessor supervisory circuits. These devices are designed to provide reliable reset signals for digital systems. The series offers various threshold options and packages to accommodate different voltage levels and space limitations in modern electronic designs.

Replacement Considerations

Check for direct substitutes within the MAX6467 family that share the same SOT-143-4 package and 3.075V threshold. Verify pinout compatibility and electrical characteristics before swapping with other supervisory ICs.
