MAX6324HUT29

Supervisors Overview

The MAX6324HUT29 is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors power supplies and microprocessor activity in digital systems, featuring a windowed (min/max) watchdog timer and manual reset input. The device provides an active-low open-drain RESET output, which asserts when the supply voltage falls below the fixed 2.9V threshold or upon manual assertion. Valid RESET output is guaranteed down to VCC = +1.2V. It operates within a supply voltage range of up to 5.5V and supports a wide operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect out-of-window microprocessor activity
• Provides manual reset capability via dedicated MR input pin
• Features open-drain RESET output for flexible system interfacing
• Ensures valid RESET signal integrity at low supply voltages

Supervisors Applications

• Microprocessor power supply monitoring
• Digital system watchdog supervision
• Embedded controller reset management

Supervisors Procurement Notes

Verify the specific suffix 'HUT' against the manufacturer's official datasheet to confirm package type and thermal characteristics. Confirm RoHS compliance status through current documentation. Check for obsolescence notices as Maxim products may have lifecycle changes. Ensure the open-drain output configuration matches your system design requirements before procurement.

Supervisors Selection Notes

Select this component when an open-drain reset output is required rather than push-pull. Verify that the fixed 2.9V threshold aligns with your system's brown-out detection needs. Consider the SOT-23-6 package constraints for PCB layout. Ensure the watchdog timer window settings are compatible with your processor's clock frequency and interrupt latency.

Supervisors Part Context

This part belongs to the MAX6323/MAX6324 family of µP supervisory circuits. The MAX6324 variant specifically offers an open-drain output, distinguishing it from the push-pull MAX6323. These devices are designed for robust power management in embedded applications requiring reliable reset generation and activity monitoring.

Supervisors Replacement Considerations

MAX6323HUT29+ offers identical functionality but with a push-pull output instead of open-drain. MAX6324AUT29+T is a tape-and-reel version of the same electrical specification. Verify pinout compatibility and output drive requirements when substituting.
