MAX6323DUT46

Supervisors Overview

The MAX6323DUT46+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed to monitor power supplies and system activity in digital applications. It features a windowed watchdog timer with manual reset capability and operates within an extended temperature range of -40°C to +125°C. The device utilizes a SOT-23-6 surface-mount package and supports a maximum supply voltage of 5.5V. Key electrical parameters include a typical operating current of 27µA, a reset delay time of 280ms, and a power dissipation rating of 696mW. The part offers multiple threshold voltage options including 2.5V, 3V, 3.3V, and 5V, ensuring compatibility with various logic families.

Supervisors Feature Summary

• Integrates a windowed watchdog timer to detect abnormal system activity outside expected operational windows.
• Provides active low push-pull reset output for reliable signal interfacing with microprocessors.
• Includes a manual reset input allowing external assertion of the reset state when required.

Supervisors Applications

• Monitoring power supplies in embedded digital systems
• Ensuring system stability in industrial control environments
• Protecting microprocessor activity in consumer electronics

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific lot traceability requirements before finalizing procurement orders. Ensure packaging specifications match production line handling needs. Cross-reference datasheet revisions to confirm parameter consistency with design specifications.

Supervisors Selection Notes

Select this component when a windowed watchdog function and manual reset capability are required alongside standard voltage supervision. Consider the 27µA operating current for battery-sensitive designs. Verify that the available threshold voltages align with the target supply rail. Evaluate the SOT-23-6 footprint against PCB layout constraints and thermal dissipation requirements for the specific application environment.

Supervisors Part Context

This part belongs to the MAX6323D series of uP supervisory circuits from Maxim Integrated. It shares functional similarities with other parts in the family but differs in specific threshold voltages and package configurations. The D suffix typically denotes a specific threshold variant within the broader MAX6323 product line, distinguishing it from other versions like the MAX6323HUT46 which may have different accuracy or threshold characteristics.

Supervisors Replacement Considerations

MAX6323DUT46+T serves as the lead-free compliant version of the MAX6323DUT46. Check for alternative suppliers such as Rochester Electronics if original manufacturing sources are unavailable. Ensure any substitute maintains the same SOT-23-6 package and pinout configuration to guarantee mechanical and electrical compatibility without redesign.
