MAX6344TUT-T

Overview

The MAX6344TUT-T is a microprocessor supervisory circuit in a SOT-23-6 package. It monitors a single voltage input with a fixed reset threshold of 4.38V and an overvoltage threshold of 4.7V. The device operates within a supply range of +1V to +5.5V, featuring a push-pull active-low output and a manual reset input. It provides a reset delay of 180ms, maintains accuracy within 1.5%, and draws 30µA of operating current. The component supports an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides factory-trimmed voltage supervision for digital system reliability
• Integrates a power-fail comparator for low-battery detection or secondary supply monitoring
• Includes a manual reset input for controlled system initialization

Applications

• Microprocessor (µP) supervisory circuits
• Digital system power supply monitoring
• Low-battery detection systems

Procurement Notes

Verify the specific suffix 'T' against official Analog Devices documentation to confirm tape-and-reel packaging requirements. Confirm RoHS compliance status as indicated by datasheet revisions. Ensure the part number matches the exact threshold voltage variant required for the design. Cross-reference the manufacturer's lifecycle status to assess long-term availability constraints.

Selection Notes

Select this component when a fixed 4.38V threshold is required for single-supervision applications. The SOT-23-6 package suits space-constrained designs. Consider the 180ms timeout and 30µA quiescent current for power-sensitive environments. Verify compatibility with the system's maximum supply voltage of 5.5V and operational temperature extremes.

Part Context

This part belongs to the MAX6342–MAX6345 family of µP supervisory circuits designed to improve system reliability. These devices offer factory-trimmed thresholds ranging from 2.33V to 4.63V. The family integrates power-fail comparators and manual reset capabilities, replacing discrete components to enhance accuracy and reduce board space in digital systems.
