MAX6323CUT29+

Supervisors Overview

The MAX6323CUT29+ 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 watchdog timer and manual reset capability. The device operates within a supply voltage range of +1.2V to +5.5V, with a fixed reset threshold of 2.93V. It offers ±2.5% accuracy for the reset threshold and consumes 27µA of operating current. The RESET output is push-pull and remains asserted low when the supply falls below the threshold or the manual reset input is activated. The component is housed in a SOT-23-6 package and supports an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect system activity outside expected operational windows
• Provides manual reset functionality via a dedicated input pin
• Delivers active-low push-pull reset output guaranteed down to 1.2V supply voltage
• Features laser-trimmed reset thresholds with high accuracy

Supervisors Applications

• Monitoring power supplies in digital systems
• Microprocessor activity supervision
• Embedded system reset management

Supervisors Procurement Notes

Verify the specific suffix 'CUT29+' against official Analog Devices documentation to confirm the exact threshold voltage and packaging configuration. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet revision. Cross-reference the part number with authorized distributors to avoid counterfeit components. Validate that the manual reset and watchdog inputs align with the system design logic.

Supervisors Selection Notes

Select this component when a fixed 2.93V reset threshold is required for single-supply monitoring. The push-pull output drives loads directly without external pull-ups. Consider the 27µA quiescent current for battery-operated applications. The wide operating temperature range suits industrial environments. Verify that the windowed watchdog timing meets the system's fault detection requirements.

Supervisors Part Context

The MAX6323 series belongs to Maxim Integrated's uP Supervisory Circuits family, designed for reliable power management in embedded systems. This specific variant provides a fixed threshold option among several available laser-trimmed values. The series integrates watchdog and manual reset functions into a compact SOT-23-6 package, simplifying board layout compared to discrete solutions.

Supervisors Replacement Considerations

Check for MAX6323 variants with different threshold voltages if the 2.93V level is unsuitable. The MAX6324 offers an open-drain output instead of push-pull. Verify pinout compatibility before substituting with other supervisor ICs from the same or competing manufacturers.
