MAX6324BUT29

Supervisors Overview

The MAX6324BUT29 is a microprocessor supervisory circuit featuring a windowed watchdog timer and manual reset. It monitors power supplies with a fixed 2.93V threshold and includes an open-drain active-low RESET output. The device operates within a supply voltage range up to 5.5V, ensuring valid RESET down to 1.2V. It offers 180ms reset delay and 1.5% accuracy. Operating temperatures span from -40°C to +125°C with a quiescent current of 27µA.

Supervisors Feature Summary

• Integrates a windowed watchdog timer for monitoring system activity outside expected operational windows.
• Provides manual reset input capability alongside automatic power-fail detection.
• Features an open-drain RESET output suitable for various logic families.
• Guarantees valid RESET output performance at low supply voltages.

Supervisors Applications

• Digital system power supply monitoring
• Microprocessor (µP) activity supervision
• Windowed watchdog timer implementation

Supervisors Procurement Notes

Verify the specific suffix 'BUT' against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure RoHS compliance status aligns with project regulations. Confirm availability through authorized Analog Devices or Maxim Integrated distributors, as distribution channels may vary by region.

Supervisors Selection Notes

Select this component when an open-drain output is required rather than push-pull. The fixed 2.93V threshold suits systems requiring precise under-voltage detection. Consider the 1.5% accuracy and 180ms delay for timing-sensitive applications. Verify that the SOT-23-6 package fits the PCB layout constraints.

Supervisors Part Context

Part of the MAX6323/MAX6324 family of µP supervisory circuits. The MAX6324 variant specifically provides an open-drain output, distinguishing it from the push-pull MAX6323. This family supports laser-trimmed thresholds and windowed watchdog functionality for robust system management.

Supervisors Replacement Considerations

MAX6323BUT29+T: Push-pull output instead of open-drain. MAX6324EUT46+T: Different 4.63V threshold. Verify functional equivalence before substitution.
