MAX6324GUT46

Supervisors Overview

The MAX6324GUT46+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed to monitor power supplies and processor activity in digital systems. It features a windowed watchdog timer with manual reset capability and an open-drain active-low RESET output. The device operates within a supply voltage range up to 5.5V and includes a fixed threshold of 4.63V for monitoring. Key electrical parameters include a maximum operating temperature of +125°C, a minimum operating temperature of -40°C, and a typical quiescent current of 27µA. The reset delay time is specified at 180ms, ensuring stable system recovery during power transitions.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect abnormal processor activity outside expected operational windows
• Provides manual reset functionality via a dedicated MR input pin for controlled system initialization
• Features an open-drain active-low RESET output that remains asserted low when supply voltage falls below the threshold

Supervisors Applications

• Monitoring power supplies in embedded digital systems
• Ensuring processor activity stability through windowed watchdog supervision
• Providing manual reset control for system initialization sequences

Supervisors Procurement Notes

Verify the exact suffix and manufacturer designation when sourcing, as availability may vary between Analog Devices and Maxim Integrated channels. Confirm RoHS compliance status and packaging type (Reel or Cut Tape) against specific project requirements. Check for obsolescence notices or limited supply alerts from authorized distributors before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.63V threshold is required for single-supply monitoring applications. The open-drain output suits designs needing wired-OR configurations or level shifting. Ensure the SOT-23-6 package fits the PCB layout constraints. Consider the 180ms reset delay and 27µA quiescent current against system power and timing specifications.

Supervisors Part Context

This part belongs to the MAX6324 series of microprocessor supervisory circuits, which offer various laser-trimmed reset thresholds. The 'G' suffix typically denotes a specific temperature grade or manufacturing lot variation within the Maxim Integrated portfolio. These devices are commonly used in industrial and consumer electronics requiring reliable power management and processor oversight.

Supervisors Replacement Considerations

Direct substitutes include other MAX6324 variants with different threshold voltages (e.g., MAX6324EUT46+T for 4.63V, MAX6324AUT29+T for 2.5V/3V/3.3V/5V options). Verify pin compatibility and output type (open-drain vs. push-pull) when considering cross-references from other manufacturers.
