MAX6361PUT31+T

Overview

The MAX6361PUT31+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 voltage of 3.08 V. The device provides an active high, open-drain output with a manual reset input and a battery backup switch. It includes a fixed reset delay time of 280 ms and consumes only 15 uA of operating current. The component is housed in a compact SOT-23-6 package and supports surface mount installation.

Feature Summary

• Integrates a manual reset input for system control alongside automatic voltage monitoring
• Provides battery backup switching functionality to maintain system state during power transitions
• Delivers an active high open-drain output signal for direct interface with logic circuits

Applications

• Microprocessor power supply supervision
• Battery-powered electronic systems requiring voltage monitoring
• Portable devices needing low quiescent current management

Procurement Notes

Verify the exact suffix configuration against official datasheets to ensure correct threshold voltage and package type. Confirm availability status as distribution channels may list limited stock or end-of-life statuses. Cross-reference manufacturer part numbers with authorized distributors to avoid counterfeit components. Check RoHS compliance documentation for specific regulatory requirements.

Selection Notes

Select this component when an active high output polarity is required for the specific logic family being monitored. The inclusion of a manual reset pin distinguishes it from variants lacking this feature. Ensure the 3.08 V threshold aligns with the target supply rail. Consider the SOT-23-6 footprint constraints during PCB layout planning.

Part Context

This part belongs to the MAX6361 series of low-power MPU supervisors. It shares the same core architecture and low current consumption characteristics as other members of the family but differs in output polarity and specific threshold settings. The series is designed for applications where space and power efficiency are critical constraints.

Replacement Considerations

Direct substitutes include other MAX6361 variants with matching active high outputs and similar thresholds, such as MAX6361PUT44+T. Verify that replacement parts maintain the same SOT-23-6 package and manual reset capability.
