MAX6324AUT46-T

Supervisors Overview

The MAX6324AUT46-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.5 V to 5.5 V and features a fixed reset threshold voltage of 4.63 V with an accuracy of 1.5%. The device provides an active low, open-drain output and includes a manual reset input alongside a windowed watchdog timer. It functions reliably across an extended temperature range from -40°C to +125°C while consuming only 27 µA of quiescent current.

Supervisors Feature Summary

• Integrates a windowed watchdog timer for system fault detection
• Includes a manual reset input for controlled system initialization
• Provides active low open-drain reset output signal

Supervisors Applications

• Portable battery-powered equipment requiring low power consumption
• Microprocessor-based systems needing reliable voltage supervision
• Industrial control units operating in extreme temperature environments

Supervisors Procurement Notes

Verify the exact suffix against official manufacturer documentation, as standard distribution often utilizes the +T designation. Confirm RoHS compliance status through the specific datasheet revision. Ensure the selected variant matches the required package type and temperature grade for your specific design constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for monitoring higher voltage rails. The inclusion of a manual reset pin allows for external control over system restarts. Consider the open-drain output configuration for compatibility with various logic levels. Verify that the 27 µA current draw meets the standby power requirements of the application.

Supervisors Part Context

This part belongs to the MAX6324A series of ultra-low-power microprocessor supervisors. The family is designed to provide essential reset functionality for digital systems. Variants within the series differ primarily in reset threshold voltages and package options, allowing designers to tailor supervision circuits to specific voltage rails without changing the core functional architecture.

Supervisors Replacement Considerations

Cross-reference with other MAX6324 variants featuring different threshold voltages if the 4.63 V setting is unsuitable. Check for updated generations within the Maxim Integrated portfolio that may offer improved specifications or alternative packaging solutions while maintaining pin compatibility.
