MAX6324EUT46

Supervisors Overview

The MAX6324EUT46+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1V to 5.5V and features a fixed threshold voltage of 4.63V with 1.5% accuracy. The device provides an active low, open-drain output and includes a manual reset input alongside a windowed watchdog timer. It exhibits a reset delay time of 180ms and consumes 27µA of quiescent current. Designed for surface-mount installation, it is housed in a compact SOT-23-6 package and supports an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a windowed watchdog timer for system reliability monitoring
• Includes a dedicated manual reset input for user-initiated control
• Features ultra-low power consumption suitable for battery-operated devices
• Provides factory-programmed reset thresholds with high precision

Supervisors Applications

• Portable electronic equipment requiring low standby current
• Microprocessor systems needing watchdog protection
• Battery-powered consumer electronics
• Industrial control units operating in extreme temperatures

Supervisors Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade (+125°C) when sourcing replacements. Confirm the '+T' designation corresponds to tape-and-reel packaging if continuous production is required. Ensure compatibility with existing PCB footprints for the SOT-23-6 package. Check for RoHS compliance documentation as per regional regulations. Validate that the open-drain output configuration matches the downstream logic requirements.

Supervisors Selection Notes

Select this component when both manual reset capability and watchdog functionality are required in a single package. The SOT-23-6 form factor offers space efficiency compared to larger packages. The 1.5% threshold accuracy ensures precise supervision for sensitive digital circuits. Consider the 27µA current draw against stricter low-power alternatives if battery life is critical. Verify that the open-drain output can drive the necessary load without external pull-up resistors exceeding specifications.

Supervisors Part Context

This part belongs to the MAX6324 series of microprocessor supervisory circuits. It shares functional similarities with other Maxim Integrated supervisors but is distinguished by its specific combination of manual reset and windowed watchdog features. The series is designed to replace older discrete supervisor designs, offering integrated protection in a minimal footprint for modern embedded applications.

Supervisors Replacement Considerations

Direct substitutes include other MAX6324 variants with different threshold voltages or package options, provided the electrical characteristics match the application requirements.
