MAX6323AUT46

Supervisors Overview

The MAX6323AUT46 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 up to 5.5 V and includes a fixed reset threshold of 4.63 V with ±1.5% accuracy. It provides an active low push-pull output and maintains valid reset signals down to 1.2 V. The component supports a manual reset input and offers a reset delay time of 180 ms. It functions reliably across an extended temperature range from -40°C to +125°C while consuming only 27 µA of quiescent current.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect out-of-specification system activity
• Includes a manual reset input for external control of the reset state
• Provides a push-pull active low output ensuring valid reset down to 1.2 V
• Features laser-trimmed high-accuracy reset thresholds

Supervisors Applications

• Monitoring power supplies in embedded digital systems
• Ensuring microprocessor activity compliance via watchdog functionality
• Providing manual reset control in industrial control units

Supervisors Procurement Notes

Verify the specific suffix 'AUT46' against official datasheets to confirm the exact threshold voltage and package configuration. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Ensure the operating environment matches the specified temperature range and voltage limits before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold and windowed watchdog are required. Compare against the MAX6323DUT46 if a different threshold or open-drain output is needed. Consider the MAX6323HUT46 for alternative threshold options. Verify that the SOT-23-6 package fits the design constraints and that the 27 µA current consumption meets power budget requirements.

Supervisors Part Context

This part belongs to the MAX6323 series of uP supervisory circuits designed for monitoring power rails and processor activity. It shares functional similarities with the MAX6324 but differs in output type. The series is characterized by low power consumption and high accuracy, making it suitable for battery-powered and space-constrained applications requiring reliable system supervision.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include MAX6323DUT46+T and MAX6323HUT46+T. Verify electrical compatibility regarding threshold voltages and output drive capabilities before substitution.
