MAX6324HUT23+

Supervisors Overview

The MAX6324HUT23+ is a microprocessor supervisory circuit from Analog Devices Inc./Maxim Integrated, housed in a SOT-23-6 package. It monitors a single voltage input with a fixed threshold of 2.32V and features an open-drain output type. The device includes a watchdog timer and manual reset functionality, with a reset delay time of 280 ms. It operates within a supply voltage range up to 5.5 V and maintains accuracy within ±2.5%. The component supports operation temperatures from -40°C to +125°C and consumes 27 µA of quiescent current.

Supervisors Feature Summary

• Monitors power supplies and microprocessor activity in digital systems
• Features a windowed watchdog timer for detecting abnormal system behavior
• Provides manual reset capability via dedicated input pin
• Guarantees valid reset output down to 1.2V supply voltage

Supervisors Applications

• Microprocessor supervisory circuits
• Digital system power monitoring
• Embedded controller applications

Supervisors Procurement Notes

Verify the specific suffix 'HUT23+' ensures the correct 2.32V threshold and open-drain configuration. Confirm RoHS compliance status through official documentation. Check availability as distribution may vary by region. Ensure the SOT-23-6 package matches your PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this part when a fixed 2.32V threshold is required for single-supply monitoring. Choose the open-drain output variant if level shifting or wired-OR configurations are needed. Consider the 27 µA quiescent current for low-power designs. Verify that the 280 ms reset delay meets your system startup timing constraints.

Supervisors Part Context

This component belongs to the MAX6323/MAX6324 family of µP supervisory circuits. The MAX6324 variant specifically offers an open-drain RESET output, distinguishing it from the push-pull MAX6323. The family provides laser-trimmed thresholds with high accuracy for reliable system protection in industrial and commercial environments.

Supervisors Replacement Considerations

MAX6323HUT23+T: Similar function but with push-pull output instead of open-drain. MAX6324HUT29+: Same open-drain output but with a 2.93V threshold. Verify output drive capability and threshold voltage compatibility before substitution.
