MAX6361LUT26+T

Overview

The MAX6361LUT26+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.8V to 5.5V and consumes only 15µA of operating supply current. The device features a fixed reset threshold voltage of 2.63V with a typical overvoltage threshold of 2.7V. It provides a manual reset input and offers an active-low push-pull reset output. The reset timeout delay is specified at 280ms. The component is housed in a compact SOT-23-6 surface-mount package and supports operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates manual reset functionality for controlled system initialization
• Provides active-low push-pull reset output for direct logic interfacing
• Monitors single power-supply voltage with factory-set thresholds

Applications

• Microprocessor (MPU) power supply monitoring
• Battery backup switching circuits
• Portable electronic devices requiring low quiescent current

Procurement Notes

Verify the specific suffix 'LUT26' to confirm the 2.63V threshold voltage, as the MAX6361 series utilizes alphanumeric codes to denote distinct reset levels. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to integration. Ensure the SOT-23-6 footprint matches the target PCB design constraints. Validate that the active-low output polarity aligns with the receiving logic gate requirements.

Selection Notes

Select this component when a fixed 2.63V supervision level is required for systems powered between 1.8V and 5.5V. The 15µA supply current makes it suitable for battery-operated applications where power conservation is critical. Choose this part if an active-low push-pull output is preferred over open-drain configurations. Verify that the 280ms timeout duration meets the startup timing requirements of the monitored microprocessor or memory device.

Part Context

This device belongs to the MAX6361–MAX6364 family of supervisory circuits designed to simplify power-supply monitoring and battery control functions. These circuits reduce component count and board space compared to discrete solutions. The MAX6361 variant specifically focuses on low-power MPU supervision with manual reset capabilities, distinguishing it from watchdog-enabled or multi-channel counterparts in the broader Maxim Integrated portfolio.

Replacement Considerations

Cross-reference other MAX6361 variants with different suffixes (e.g., LUT29, LUT44) to match specific threshold voltages such as 2.9V or 4.4V. Ensure any substitute maintains the SOT-23-6 package and active-low push-pull output characteristics. Verify that alternative parts support the same 1.8V to 5.5V operating range and 15µA current consumption profile.
