MAX6364LUT46+

Overview

The MAX6364LUT46+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 4.60V with a corresponding overvoltage threshold of 4.699V. The device provides an active-low, push-pull output and includes a manual reset input alongside a watchdog timer function. It incorporates a battery backup switch for seamless power transition monitoring. The reset delay time is specified at 280ms, and the circuit draws a typical operating supply current of 15µA. It is housed in a compact SOT-23-6 package and supports operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates a watchdog timer and manual reset input for comprehensive system control
• Includes a battery backup switch to monitor power source transitions
• Provides active-low push-pull output for direct interface with logic circuits

Applications

• Portable equipment requiring low standby current
• Battery-powered systems with backup power monitoring
• Microprocessor-based embedded controllers

Procurement Notes

Verify availability status as distribution channels may indicate limited stock or special order requirements. Confirm the exact suffix matches the required package and temperature grade. Ensure the component meets RoHS compliance standards for your region. Cross-reference the manufacturer date code to ensure freshness. Validate that the specific ordering number aligns with the intended application voltage thresholds.

Selection Notes

Select this component when a fixed 4.6V threshold is required for system supervision. Consider the integrated watchdog and manual reset features if complex reset sequencing is needed. Evaluate the 15µA quiescent current against strict power budget constraints. Verify that the SOT-23-6 footprint fits the PCB layout limitations. Ensure the operating temperature range covers the environmental conditions of the final assembly.

Part Context

This part belongs to the MAX6363/MAX6364 family of low-power supervisors designed for portable applications. These devices are engineered to provide reliable reset signals for microprocessors and memory systems. The family distinguishes itself through low supply current consumption and small package options. They support various threshold voltages and include additional features like watchdog timers and battery backup switches.

Replacement Considerations

Check for MAX6364 variants with different threshold voltages if the 4.6V setting is not suitable. Verify pin compatibility with other SOT-23-6 supervisor ICs from the same manufacturer. Ensure substitute parts maintain similar quiescent current specifications for power-sensitive designs.
