MAX6361HUT46-T

Overview

The MAX6361HUT46-T is a low-power microprocessor supervisor circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 4.63 V. The device provides an active high, open-drain reset output with a typical reset delay time of 150 ms. It includes manual reset functionality and battery backup switching capabilities but lacks a watchdog timer. The component is housed in a compact SOT-23-6 surface-mount package and supports operation across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides reliable voltage supervision with a fixed 4.63 V threshold for system monitoring
• Features manual reset input allowing user-initiated system resets
• Includes battery backup switch function to manage power source transitions
• Delivers active high open-drain reset signal compatible with various logic families

Applications

• Microprocessor power supply monitoring

Procurement Notes

Verify the exact suffix designation, as datasheets may list MAX6361HUT46+T while market listings use MAX6361HUT46-T. Confirm RoHS compliance status through official manufacturer documentation. Check current availability as some distributors indicate limited stock or discontinuation status for specific variants. Ensure the selected part matches the required threshold voltage and package type for your design.

Selection Notes

Select this component when a fixed 4.63 V threshold is required for system supervision. It is suitable for designs needing manual reset capability and battery backup switching without watchdog functionality. Consider the SOT-23-6 package size for space-constrained applications. Verify that the active high open-drain output aligns with the target microprocessor's reset input requirements.

Part Context

This part belongs to the MAX6361H series of low-power MPU supervisors from Maxim Integrated. The series offers various threshold voltages and packaging options. The H-grade variant indicates extended temperature performance compared to standard commercial grades. It is designed for applications requiring precise voltage monitoring with minimal quiescent current consumption.

Replacement Considerations

Check for MAX6361HUT31+T or MAX6361HUT44+T if different threshold voltages are acceptable. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement maintains the same package type and functional features such as manual reset and battery backup support.
