MAX6364LUT31+T

Overview

The MAX6364LUT31+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within an input voltage range of 0V to 5.5V and features a fixed overvoltage threshold of 3.15V. The device draws an operating supply current of 15µA and dissipates up to 696mW. Packaged in a compact 6-pin SOT-23, it includes battery backup functionality but lacks power fail detection capabilities.

Feature Summary

• Integrates battery backup support for continuous monitoring during primary power loss
• Provides fixed overvoltage supervision with a specific 3.15V threshold
• Designed for ultra-low power consumption suitable for battery-operated systems

Applications

• Low-power microprocessor system supervision
• Battery-backed embedded control circuits
• Portable electronic device power management

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the presence of the '+' suffix indicating lead-free compliance. Check current availability status as some listings indicate obsolete or limited stock conditions. Ensure the SOT-23-6 package matches your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 3.15V overvoltage threshold is required without power-fail detection. The 15µA supply current makes it suitable for energy-constrained applications. Verify that the SOT-23-6 package fits the design constraints. Consider alternative models if adjustable thresholds or additional monitoring channels are needed for the specific application.

Part Context

This part belongs to the MAX6364 series of supervisory circuits designed for microprocessor protection. It offers a simplified solution for overvoltage monitoring compared to more complex multi-channel supervisors. The series is characterized by low quiescent current and small footprint options, targeting portable and industrial electronics where space and power efficiency are critical design factors.
