ADM8323WCC29ARJZR7

Supervisors Overview

The ADM8323WCC29ARJZR7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage rails in electronic systems. It operates within an extended temperature range of -40°C to +125°C and is qualified for automotive applications. The device features a fixed reset threshold voltage of 2.93V with a minimum reset timeout of 140ms. It utilizes a push-pull/totem pole output configuration and includes a built-in windowed watchdog timer alongside a manual reset input. The component is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Integrates a windowed watchdog timer for system fault detection
• Includes a manual reset input for controlled system recovery
• Features push-pull/totem pole output stage for robust drive capability
• Qualified for automotive grade reliability standards

Supervisors Applications

• Automotive electronic control units requiring voltage supervision
• Industrial systems with embedded watchdog functionality needs
• Portable devices utilizing low-voltage power management
• Embedded controllers needing manual reset capabilities

Supervisors Procurement Notes

Verify the specific suffix ARJZR7 corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the automotive qualification status meets the specific AEC-Q100 or internal manufacturer standards applicable to your production environment. Ensure the SOT-23-5 footprint matches your PCB design guidelines before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is appropriate for the monitored rail. The integrated watchdog timer eliminates the need for external timing components, simplifying board layout. The push-pull output allows direct interfacing with digital logic without additional pull-up resistors. Consider the 140ms minimum timeout duration to ensure compatibility with the target system's startup sequence requirements.

Supervisors Part Context

This part belongs to the ADM8323 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and timeout options within the same SOT-23-5 package family. The WCC29A designation indicates the specific voltage threshold and feature set. This series is positioned for applications requiring reliable power monitoring with minimal external component count.

Supervisors Replacement Considerations

Check for ADM8323 variants with different threshold voltages if the 2.93V setting does not match the new application rail. Verify pinout compatibility with other SOT-23-5 supervisors from Analog Devices or competitors. Ensure the replacement maintains the push-pull output type and watchdog functionality if these features are critical to the design.
