MAX6324AUT31-T

Supervisors Overview

The MAX6324AUT31-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for voltage monitoring applications. It operates within a supply voltage range of 1V to 5.5V and features an active-low open-drain output. The device includes a manual reset input and a windowed watchdog timer with a fixed timeout period of 280ms. It monitors a single input with a threshold voltage of 3.1V and an overvoltage threshold of 3.2V. The component is housed in a compact SOT-23-6 package and supports surface-mount installation. It functions reliably across an extended industrial temperature range from -40°C to +125°C while consuming a low operating supply current of 27µA.

Supervisors Feature Summary

• Integrates a windowed watchdog timer with manual reset capability for enhanced system reliability
• Provides precise voltage supervision with dedicated overvoltage detection thresholds
• Features an active-low open-drain output compatible with various logic families
• Operates efficiently at low currents suitable for battery-powered or power-sensitive designs

Supervisors Applications

• Microprocessor reset circuits requiring watchdog functionality
• Portable electronic devices with limited power budgets

Supervisors Procurement Notes

Verify availability status as distribution channels may indicate restricted supply or discontinuation. Confirm exact ordering suffixes match required specifications. Check RoHS compliance documentation for regulatory requirements. Validate package type against PCB footprint constraints. Ensure temperature grade matches application environment needs before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a windowed watchdog timer is necessary alongside voltage supervision. Consider the 280ms timeout duration for system timing requirements. Evaluate the SOT-23-6 package size for space-constrained layouts. Verify that the 3.1V threshold aligns with the monitored rail voltage. Assess the 27µA quiescent current impact on overall system power consumption.

Supervisors Part Context

This part belongs to the MAX6324A series of supervisory circuits designed for microprocessor applications. The series offers various threshold voltages and packages to suit different design needs. The AUT suffix indicates automotive-grade qualification and specific temperature ranges. The T suffix denotes tape-and-reel packaging for automated assembly processes.

Supervisors Replacement Considerations

Consult official datasheets for direct pin-compatible alternatives within the MAX6324 family. Verify threshold voltage compatibility when substituting with other variants. Check package dimensions for mechanical fit in existing designs. Ensure functional equivalence regarding watchdog timer behavior and reset delay times.
