MAX6361LUT31+T

Overview

The MAX6361LUT31+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a fixed reset threshold of 3.08 V. The device provides a manual reset input and an active-high, push-pull output. It includes battery backup functionality and offers a typical reset delay time of 280 ms. Designed for surface-mount installation, it is housed in a compact SOT-23-6 package and consumes only 15 µA of operating current.

Feature Summary

• Provides reliable system supervision with a fixed 3.08 V threshold for precise voltage monitoring
• Features a manual reset input allowing user-initiated system resets independent of voltage levels
• Includes battery backup capability to maintain supervision during power transitions or outages
• Delivers an active-high push-pull output signal for direct interface with microprocessor reset pins

Applications

• Microprocessor (MPU) power supply supervision in embedded systems
• Battery-powered devices requiring low quiescent current monitoring
• Systems needing manual reset control alongside automatic voltage supervision
• Portable electronics utilizing battery backup for continuous operation

Procurement Notes

Verify the specific suffix 'UT31' corresponds to the 3.08 V threshold variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Check for end-of-life or limited availability notices, as this component may be discontinued or restricted in certain regions. Ensure the SOT-23-6 package matches your PCB footprint requirements before procurement.

Selection Notes

Select this component when a fixed 3.08 V threshold is required for MPU supervision. Choose the active-high push-pull output configuration if interfacing with logic that requires this polarity. Consider the 15 µA current consumption for battery-sensitive applications. Verify that the SOT-23-6 package fits the design constraints. Ensure the manual reset feature aligns with the system's reset strategy.

Part Context

This part belongs to the MAX6361H/L series of low-power microprocessor supervisors. These circuits are designed to monitor single power supplies and provide reset signals to microprocessors. The series typically offers various threshold voltages and output configurations to suit different system requirements while maintaining low power consumption.

Replacement Considerations

Check for other MAX6361 variants with different threshold voltages if 3.08 V is not suitable. Compare with MAX6364 series for similar functionality but verify pinout compatibility. Ensure any substitute maintains the SOT-23-6 package and active-high push-pull output characteristics.
