ADM6321CY46ARJZ-R7

Supervisors Overview

The ADM6321CY46ARJZ-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 utilizes a 5-lead SOT-23 package. The device features a fixed reset threshold voltage of 4.6 V. Key functional specifications include a maximum operating supply voltage of 5.5 V, a typical quiescent current of 5 μA, and guaranteed reset output validity down to a supply voltage of 1 V. The component provides glitch immunity and supports manual reset input functionality.

Supervisors Feature Summary

• Integrates watchdog timer and manual reset capabilities for comprehensive system supervision
• Provides low power consumption with a typical quiescent current of 5 μA
• Ensures reliable operation through power supply glitch immunity
• Maintains valid reset output signals even at low supply voltages down to 1 V

Supervisors Applications

• Embedded systems requiring robust power supply monitoring
• Microcontroller-based designs needing watchdog protection
• Industrial equipment operating in extreme temperature environments
• Portable devices prioritizing low standby power consumption

Supervisors Procurement Notes

Verify the specific suffix 'RJZ' against official documentation to confirm RoHS compliance status and lead-free characteristics. Ensure the order quantity matches the manufacturer's reel or cut tape requirements. Confirm that the 4.6 V threshold aligns precisely with the target application's voltage monitoring needs before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 4.6 V threshold is required for single-supervision applications. Consider the 5 μA quiescent current for battery-operated designs where power efficiency is critical. Verify compatibility with the 5-lead SOT-23 footprint during PCB layout. Evaluate the need for manual reset inputs if user intervention is necessary for system recovery.

Supervisors Part Context

This part belongs to the ADM632x series of supervisory circuits from Analog Devices. The series offers various threshold options and timeout configurations. The ADM6321 variant specifically denotes a single-channel configuration with integrated watchdog functionality. It shares common package and interface standards with other members of the family while differing in specific electrical thresholds.

Supervisors Replacement Considerations

Substitute parts must match the 4.6 V threshold, SOT-23-5 package, and industrial temperature range. Verify equivalent watchdog timeout options and manual reset support. Cross-reference pinouts to ensure direct compatibility without schematic modifications.
