MAX6361HUT31

Overview

The MAX6361HUT31+T is a low-power microprocessor (MPU) supervisory circuit manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed reset threshold of 3.15 V. The device provides an active high, open-drain output with a manual reset input capability. It includes battery backup switching functionality and offers a reset delay time of 280 ms. Designed for surface-mount installation in a SOT-23-6 package, it supports operation temperatures from -40°C to +85°C while consuming only 15 µA of quiescent current.

Feature Summary

• Provides reliable power system monitoring with a fixed 3.15 V threshold for critical voltage supervision
• Features manual reset input allowing user-initiated system resets alongside automatic fault detection
• Integrates battery backup switch functionality to maintain data integrity during power transitions
• Delivers active high and open drain output configurations for flexible interface compatibility

Applications

• Low-power microprocessor system supervision
• Battery-powered equipment voltage monitoring
• Portable electronic device power management
• Industrial control system reset generation

Procurement Notes

Verify the complete part number including suffixes such as +T for tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Check current availability as distribution channels may indicate limited stock or discontinuation status. Ensure the selected variant matches the required operating temperature range and package type for your specific design implementation.

Selection Notes

Select this component when a fixed 3.15 V threshold is required for MPU supervision without adjustable resistor networks. Consider the manual reset feature if external user intervention capabilities are necessary. Evaluate the 15 µA quiescent current against total system power budgets for battery-operated applications. Verify that the SOT-23-6 package dimensions fit within the available PCB real estate constraints.

Part Context

This device belongs to the MAX6361H series of low-power MPU supervisors designed for portable and battery-operated electronics. The series emphasizes minimal power consumption while providing essential reset functions. Similar parts in the family may offer different thresholds or additional features like watchdog timers, but this specific model focuses on basic supervision with manual reset capability.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6361 series that match the 3.15 V threshold. Verify that any substitute maintains the same SOT-23-6 package and electrical characteristics. Ensure replacement parts support the required manual reset function and battery backup switching if these features are critical to the design.
