MAX6363LUT23-T

Overview

The MAX6363LUT23+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 2.32 V with an overvoltage threshold of 2.38 V. The device provides a reset delay time of 280 ms and draws a typical operating supply current of 15 uA. It utilizes an SOT-23-6 package and supports battery backup switching. The output type is active low push-pull, and it lacks manual reset or watchdog timer functions.

Feature Summary

• Integrates battery backup switching capability for continuous monitoring during power transitions
• Provides active low push-pull reset output for direct interface with digital logic
• Designed for low-power applications with minimal quiescent current consumption

Applications

• Microprocessor system supervision in embedded controllers
• Battery-powered portable devices requiring voltage monitoring
• Industrial control systems needing reliable power failure detection

Procurement Notes

Verify the exact suffix designation (+T) against official manufacturer documentation to confirm tape-and-reel packaging specifications. Confirm availability status as distribution channels may indicate limited stock or end-of-life conditions. Ensure the component meets RoHS compliance requirements for your specific manufacturing process before integration.

Selection Notes

Select this component when a fixed 2.32 V threshold is required for single-input voltage monitoring. Consider the SOT-23-6 package constraints for board space limitations. Evaluate the 15 uA supply current against total system power budgets. Verify that the absence of a watchdog timer aligns with the system's safety architecture requirements.

Part Context

This part belongs to the MAX6363L series of low-power microprocessor supervisors. It is designed to monitor a single voltage rail and assert a reset signal when the supply drops below the specified threshold. The series typically includes variants with different thresholds and output configurations to suit various application needs.

Replacement Considerations

Check for MAX6363PUT23+T if an open-drain output is preferred instead of push-pull. Verify other MAX6363L variants with similar threshold voltages if slight adjustments are acceptable. Consult official substitution guides for pin-compatible alternatives within the same product family.
