ADM823LYRJZ-R7

Supervisors Overview

The ADM823LYRJZ-R7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed under-voltage threshold of 4.63 V with an over-voltage threshold of 4.7 V. The device includes a manual reset input, a watchdog timer, and provides a push-pull output. It is housed in a SOT-23-5 package and supports operation from -40 °C to +125 °C.

Supervisors Feature Summary

• Integrated watchdog timer for system monitoring
• Manual reset capability via dedicated input pin
• Push-pull output driver configuration

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset management
• Watchdog timer implementation in industrial controllers

Supervisors Procurement Notes

Verify the specific suffix 'L' indicates the 4.63 V threshold variant against official datasheets. Confirm RoHS compliance status and manufacturing origin details directly with authorized distributors or Analog Devices. Ensure the SOT-23-5 package marking matches the required identification standards for your assembly process.

Supervisors Selection Notes

Select this component when a fixed 4.63 V under-voltage detection level is required alongside integrated watchdog functionality. The SOT-23-5 package suits space-constrained designs. Verify that the 4.7 V over-voltage threshold aligns with the target system's maximum allowable input voltage limits before finalizing the design.

Supervisors Part Context

This part belongs to the ADM823 series of supervisory circuits from Analog Devices. These devices are designed to monitor supply voltages and provide reset signals to protect sensitive electronics. The series typically offers various threshold options and packaging configurations to accommodate different system requirements.

Supervisors Replacement Considerations

Check for ADM823 variants with different threshold voltages if the 4.63 V level is unsuitable. Verify pinout compatibility with alternative supervisory ICs from other manufacturers before substitution.
