MAX6361HUT23

Overview

The MAX6361HUT23 is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range up to 5.5 V and features an active-high, open-drain output. The device includes manual reset functionality and battery backup switching. Key electrical parameters include a reset delay time of 280 ms, a quiescent current of 15 uA, and an overvoltage threshold of 2.3 V. It is housed in a SOT-23-6 package and supports operation from -40°C to +85°C.

Feature Summary

• Provides reliable system reset monitoring with active-high open-drain output
• Includes manual reset input for user-initiated control
• Integrates battery backup switch for seamless power transition
• Designed for low-power applications with minimal quiescent current consumption

Applications

• Microprocessor system supervision
• Battery-powered portable devices
• Embedded controller reset circuits
• Power management systems requiring manual reset capability

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure packaging specifications match handling needs. Check for obsolescence notices or lifecycle changes that may affect long-term supply stability.

Selection Notes

Select this component when an active-high output signal is required for supervisor logic compatibility. The inclusion of a manual reset pin distinguishes it from variants lacking this feature. Verify that the 2.3 V threshold aligns with the monitored rail's minimum operating voltage. Consider the SOT-23-6 footprint for PCB layout constraints.

Part Context

This part belongs to the MAX6361 series of low-power MPU supervisors. Variants differ primarily by output polarity (active-high vs. active-low), presence of manual reset, and specific threshold voltages. The 'HUT' suffix indicates the active-high version with manual reset in a SOT-23-6 package.

Replacement Considerations

Cross-reference with MAX6361PUT23 for active-low equivalent functionality. Verify pinout compatibility if substituting with other SOT-23-6 supervisors. Ensure threshold voltage matches application requirements when selecting alternative parts.
