ADM8321WAX30ARJZR7

Supervisors Overview

The ADM8321WAX30ARJZR7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for surface-mount installation in SOT-23-5 packages. It features a fixed threshold voltage of 3 V and provides an active high, push-pull output. The device includes manual reset functionality but lacks a watchdog timer or battery backup switch. It operates within a supply voltage range up to 5.5 V maximum, with a reset delay time of 1.4 ms and accuracy of 1.5%. The component supports an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates manual reset capability for system control
• Provides active high push-pull output configuration
• Supports wide operating temperature ranges

Supervisors Applications

• Voltage monitoring in embedded systems
• Power management supervision in industrial equipment
• Automotive electronic circuit protection

Supervisors Procurement Notes

Verify the specific suffix ARJZR7 against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with SOT-23-5 footprint requirements during PCB layout. Confirm that the absence of a watchdog timer aligns with system design needs, as this variant relies solely on voltage supervision and manual reset functions without additional timing features.

Supervisors Selection Notes

Select this component when an active high output is required rather than the more common open-drain configuration found in similar supervisors. The 3 V threshold suits applications monitoring 3.3 V logic rails. Consider the push-pull drive strength if interfacing directly with digital inputs without pull-up resistors. Verify that the lack of a built-in watchdog timer does not conflict with safety-critical system requirements.

Supervisors Part Context

This part belongs to the ADM8321 series of supervisory circuits from Analog Devices. It shares the SOT-23-5 form factor with other variants in the family but differs in output polarity and threshold settings. The series is designed for compact power management solutions requiring precise voltage monitoring in space-constrained environments.
