ADM823MYRJZ-R7

Supervisors Overview

The ADM823MYRJZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply voltage levels and code execution integrity. It operates within a supply voltage range of up to 5.5 V and features an overvoltage threshold of 4.45 V. The device draws an operating supply current of 24 µA and provides a push-pull output type. It supports manual reset functionality and includes a watchdog timer for system protection. The component is rated for an extended temperature range from -40°C to +125°C and is housed in a 5-lead SOT-23 package.

Supervisors Feature Summary

• Monitors power supply voltage levels and code execution integrity
• Includes integrated watchdog timer for system protection
• Supports manual reset functionality with push-pull output
• Operates across an extended industrial temperature range

Supervisors Applications

• Monitoring power supply voltage levels in embedded systems
• Ensuring code execution integrity via watchdog supervision
• Industrial control systems requiring extended temperature operation

Supervisors Procurement Notes

Verify the specific suffix 'R7' indicates tape and reel packaging configuration when sourcing. Confirm the manufacturer is Analog Devices Inc. or authorized distributor Rochester Electronics, as secondary market sources may exist. Ensure the part matches the SOT-23-5 package and 4.45 V overvoltage threshold specifications required for your design.

Supervisors Selection Notes

Select this component when a low-power supervisory circuit with both voltage monitoring and watchdog capabilities is required. The 24 µA supply current makes it suitable for battery-operated applications. The 4.45 V overvoltage threshold and push-pull output are key differentiators compared to other variants in the ADM823 family.

Supervisors Part Context

This part belongs to the ADM823/ADM824/ADM825 series of supervisory circuits. These devices are engineered to provide reliable system reset and watchdog functions. The MYRJZ-R7 variant specifically denotes the SOT-23-5 package and reel packaging format, distinguishing it from other pinout or package options within the same functional family.

Supervisors Replacement Considerations

Direct substitutes include ADM823TYKSZ-R7 and ADM823ZYKSZ-R7, which share similar supervisory functions but may differ in threshold voltages or package types. Verify that the replacement maintains the required 4.45 V overvoltage threshold and push-pull output characteristics.
