ADM6321AY43ARJZ-R7

Supervisors Overview

The ADM6321AY43ARJZ-R7 is a single-channel power supply management circuit manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40 °C to +85 °C and is housed in a 5-pin SOT-23 package (MO-178AA). The device features a fixed reset threshold voltage of 4.3 V and includes a manual reset input. It is RoHS compliant and lead-free, with an ECCN code of EAR99.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring
• Includes a manual reset input capability
• Provides low power consumption operation
• Offers power supply glitch immunity

Supervisors Applications

• Microprocessor systems
• Computers
• Controllers
• Portable equipment

Supervisors Procurement Notes

Verify the specific suffix 'R7' indicates reel packaging when sourcing. Confirm RoHS compliance status matches project requirements, as non-compliant variants exist within the same family. Ensure the 4.3 V threshold aligns with target supply voltage levels. Cross-reference the manufacturer part number against official Analog Devices documentation to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 4.3 V supervision threshold is required. The inclusion of a manual reset input distinguishes it from variants lacking this feature. Verify that the SOT-23-5 footprint fits the design constraints. Consider the industrial temperature rating for environmental suitability.

Supervisors Part Context

This part belongs to the ADM63xx series of supervisory circuits from Analog Devices. These devices are designed to monitor voltage rails and provide reset signals to digital logic. The series offers various threshold voltages and output configurations to suit different system architectures.

Supervisors Replacement Considerations

ADM6321AZ43ARJZ-R7: Identical electrical specifications and threshold voltage; verify RoHS compliance differences if applicable.
