MAX6323CUT46+T

Supervisors Overview

The MAX6323CUT46+T 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 up to 5.5V with a fixed reset threshold of 4.63V. It provides an active low, push-pull output and maintains valid RESET output down to VCC = +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 to detect abnormal system activity outside expected operational windows.
• Provides manual reset functionality via a dedicated input pin for controlled system recovery.
• Delivers a push-pull RESET output that remains asserted low when the supply voltage falls below the threshold or upon manual trigger.

Supervisors Applications

• Monitoring power supplies in automotive safety-critical applications
• Supervising microprocessor activity in embedded digital systems
• Ensuring system reliability in industrial control environments

Supervisors Procurement Notes

Verify authenticity through authorized distributors as counterfeit components exist. Confirm RoHS compliance status for environmental regulations. Check lead time constraints due to potential limited availability. Ensure storage conditions meet moisture sensitivity level requirements before assembly. Validate package integrity upon receipt to prevent soldering defects during surface mount installation.

Supervisors Selection Notes

Select this part when a fixed 4.63V threshold is required for single-supply monitoring. Choose the push-pull output variant over open-drain if driving higher capacitive loads. Consider the SOT-23-6 package for space-constrained designs requiring surface mount technology. Verify that the 27µA quiescent current meets low-power system requirements.

Supervisors Part Context

This component belongs to the MAX6323 series of uP supervisory circuits. It shares functional similarities with other parts in the family but differs in reset threshold voltage and output type. The MAX6323 specifically offers a push-pull output, whereas the MAX6324 variant provides an open-drain output. Both share the same windowed watchdog and manual reset features.

Supervisors Replacement Considerations

Direct substitutes include MAX6323HUT46+T and MAX6323DUT46+T, which share identical electrical characteristics and pinouts. Verify that replacement parts maintain the same 4.63V threshold and push-pull output configuration to ensure circuit compatibility without redesign.
