MAX6323AUT29

Supervisors Overview

The MAX6323AUT29 is a microprocessor supervisory circuit designed to monitor power supplies and system activity. It features a windowed watchdog timer with manual reset capability, packaged in a compact SOT-23-6 surface-mount format. The device operates within a supply voltage range up to 5.5V and includes a fixed reset threshold of 2.93V. It provides an active-low push-pull output that remains valid down to 1.2V. The component supports a wide operating temperature range from -40°C to +125°C and consumes only 27µA of quiescent current.

Supervisors Feature Summary

• Integrates a windowed watchdog timer for detecting out-of-specification system activity
• Provides manual reset input functionality for controlled system recovery
• Features a push-pull output stage ensuring robust drive capability
• Maintains valid reset signals at low supply voltages down to 1.2V

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Watchdog timer implementation for digital system stability
• Manual reset circuit integration for industrial controllers

Supervisors Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct threshold voltage and package type. Confirm RoHS compliance status and lead times directly with authorized distributors or Analog Devices, as availability may vary by region. Cross-reference part numbers carefully to distinguish between similar variants in the MAX6323 series.

Supervisors Selection Notes

Select this component when a windowed watchdog function is required alongside manual reset capabilities. Ensure the fixed 2.93V threshold aligns with the monitored rail voltage. Consider the SOT-23-6 package constraints and the push-pull output requirement versus open-drain alternatives found in other series members.

Supervisors Part Context

This part belongs to the MAX6323/MAX6324 family of uP supervisory circuits manufactured by Maxim Integrated, now part of Analog Devices. The MAX6323 variant specifically utilizes a push-pull output, distinguishing it from the open-drain MAX6324. These devices are laser-trimmed for accuracy and designed for reliable operation in demanding digital environments.

Supervisors Replacement Considerations

Direct substitutes include other MAX6323 variants with different threshold voltages or the MAX6324 series if open-drain outputs are acceptable. Verify pin compatibility and electrical specifications before substitution.
