MAX6364LUT29+T

Overview

The MAX6364LUT29+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.0V to 5.5V and features a fixed reset threshold voltage of 2.93V. The device provides an active-low, open-drain output with a typical reset delay time of 280ms. It includes a battery backup switch for seamless power transition monitoring and supports operation across an industrial temperature range from -40°C to +85°C. The component draws a maximum quiescent current of 15µA and is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Integrates a battery backup switch to monitor transitions between main and backup power sources
• Provides a dedicated manual reset input pin for system-initiated resets
• Features a watchdog timer with timeout indicator to detect software malfunctions
• Utilizes a low-power CMOS design suitable for portable applications

Applications

• Portable consumer electronics requiring reliable power management
• Battery-operated embedded systems with backup power capabilities
• Industrial control units operating in extended temperature environments
• Handheld devices utilizing microprocessor-based architectures

Procurement Notes

Verify the specific suffix 'LUT29' to confirm the 2.93V threshold voltage and SOT-23-6 package configuration. Confirm RoHS compliance status through official manufacturer documentation. Check current availability as distribution channels may list limited stock or end-of-life status. Ensure the selected variant matches the required manual reset and watchdog functionality for the target application design.

Selection Notes

Select this component when a fixed 2.93V threshold is required for single-supply monitoring. Consider the integrated battery backup feature if the design involves dual-power source switching. Evaluate the SOT-23-6 footprint against available PCB space constraints. Verify that the open-drain output type aligns with the downstream logic interface requirements of the monitored microprocessor.

Part Context

This part belongs to the MAX6364 series of low-power microprocessor supervisors. The series is characterized by minimal quiescent current consumption and small package options designed for space-constrained portable devices. The MAX6364 specifically differentiates itself by including both a watchdog timer and a battery backup switch, offering comprehensive power integrity monitoring compared to simpler supervisor variants.

Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify that any substitute maintains the 2.93V threshold, SOT-23-6 package, and identical functional blocks including the watchdog and backup switch.
