MAX6323HUT46-T

Supervisors Overview

The MAX6323HUT46-T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an SOT-23-6 surface-mount package. It features a fixed threshold voltage of 4.63 V and an active low push-pull output. The device includes a manual reset input and a windowed watchdog timer with a reset delay time of 180 ms. It operates within a supply voltage range up to 5.5 V, consumes 27 uA of operating current, and maintains accuracy within 1.5%. The component supports an extended industrial temperature range from -40 C to +125 C.

Supervisors Feature Summary

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to discontinued status. Confirm RoHS compliance documentation matches specific lot codes. Validate package marking against official datasheet specifications to prevent counterfeit substitution. Request original manufacturer test reports for critical reliability assessments.

Supervisors Selection Notes

Select this part when a fixed 4.63 V threshold is required alongside windowed watchdog protection. Ensure the 180 ms reset delay aligns with system startup timing requirements. Verify that the SOT-23-6 footprint fits the design constraints. Consider the 1.5% accuracy tolerance for precision applications.

Supervisors Part Context

This component belongs to the MAX6323D/H series of uP supervisory circuits. It shares functional similarities with other parts in the family but differs in threshold voltage and accuracy specifications. The H suffix typically denotes higher accuracy compared to standard variants. It serves as a specialized solution for systems requiring precise voltage monitoring and automated fault recovery.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with MAX6323DUT46+T only if threshold voltage differences (2.5V/3V/3.3V/5V vs 4.63V) and accuracy variations are acceptable for the application.
