MAX6324HUT29-T

Supervisors Overview

The MAX6324HUT29-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors power supplies and microprocessor activity in digital systems. The device features a windowed watchdog timer to detect abnormal system behavior. It provides a fixed reset threshold voltage of 2.93V with ±2.5% accuracy. The output stage is open-drain, ensuring valid RESET output down to VCC = +1.2V. It is housed in a SOT-23-6 package.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to monitor microprocessor activity outside expected operational windows
• Provides an open-drain RESET output that remains asserted low when supply voltage falls below the threshold or manual reset is triggered
• Features laser-trimmed fixed reset thresholds for precise power supply monitoring

Supervisors Applications

• Microprocessor (µP) supervisory circuits in digital systems
• Power supply monitoring applications requiring watchdog functionality
• Systems needing manual reset input capability

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging if required for automated assembly. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated on the final datasheet. Ensure the part number matches the exact threshold voltage requirement of 2.93V. Check RoHS compliance status through official documentation before procurement.

Supervisors Selection Notes

Select this component when an open-drain reset output is preferred over push-pull configurations. The fixed 2.93V threshold suits applications where the supply voltage does not require adjustable supervision. Consider the SOT-23-6 package size constraints. Verify compatibility with the system's watchdog timing requirements against the device's specified window parameters.

Supervisors Part Context

This part belongs to the MAX6323/MAX6324 family of µP supervisory circuits. The MAX6323 variant offers a push-pull output, while the MAX6324, including this model, provides an open-drain output. Both families share similar watchdog and reset threshold specifications but differ in output drive capability and pinout configuration details.

Supervisors Replacement Considerations

The MAX6323HUT29+ serves as a functional substitute if a push-pull output is acceptable instead of open-drain. Verify pin compatibility and output stage differences before substitution. Other MAX632x variants with different threshold voltages may replace this unit if the 2.93V level is not critical.
