ADM6321AY30ARJZ-R7

Supervisors Overview

The ADM6321AY30ARJZ-R7 is a single-channel power supply management circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed reset threshold voltage of 3 V with an accuracy of 2.5%. The device provides a reset delay time of 1.4 ms and includes a watchdog timer function. It supports both open-drain and push-pull output configurations without a manual reset input. The component is housed in a surface-mount SOT-23-5 package and is rated for operation between -40°C and +85°C, consuming 20 µA of working current.

Supervisors Feature Summary

• Integrated watchdog timer functionality for system monitoring
• Configurable reset output stages supporting open-drain or push-pull modes
• Glitch immunity and valid reset output down to 1 V supply
• Industrial temperature range specification

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset generation
• Watchdog timer implementation in industrial electronics

Supervisors Procurement Notes

Verify the specific suffix ARJZ-R7 against the official Analog Devices datasheet to confirm the exact threshold voltage, package variant, and tape-and-reel specifications. Ensure compatibility with the target PCB footprint and reflow profile requirements for the SOT-23-5 package. Cross-reference the RoHS compliance status and lead-free designation with the latest manufacturer documentation prior to procurement.

Supervisors Selection Notes

Select this component when a fixed 3 V reset threshold is required for systems operating between 1 V and 5.5 V. Choose the ADM6321AY30ARJZ-R7 if open-drain or push-pull output flexibility is needed alongside integrated watchdog capabilities. Consider the 2.5% accuracy and 1.4 ms delay for precise timing applications. Verify that the absence of a manual reset input aligns with the system design requirements.

Supervisors Part Context

This part belongs to the ADM6321 series of supervisory circuits from Analog Devices. The series offers various reset thresholds and timeout options in a compact 5-lead SOT-23 package. The ADM6321AY30ARJZ-R7 specifically denotes the 3 V threshold variant with watchdog functionality. It is designed for low-power applications requiring reliable power management and system reset control in industrial environments.

Supervisors Replacement Considerations

Check the official Analog Devices replacement guide for direct pin-compatible alternatives within the ADM6316/ADM6322 family. Verify threshold voltage and output configuration compatibility before substitution.
