ADM812RARTZ-REEL7

Supervisors Overview

The ADM812RARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single input voltage. It operates within a supply voltage range of 1 V to 5.5 V and features a threshold voltage of 3.08 V with an accuracy of 1.5%. The device provides an active high output and includes a manual reset function, while lacking a watchdog timer or battery backup switch. It has a reset delay time of 560 ms and consumes 15 uA of operating current. The component is housed in an SOT-143-4 package and supports surface mount installation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides manual reset capability for system control
• Features active high output signal generation
• Supports surface mount installation in compact packages

Supervisors Applications

• Microprocessor power supply monitoring

Supervisors Procurement Notes

Verify the specific suffix RARTZ against official Analog Devices documentation to confirm pinout and electrical characteristics match design requirements. Confirm availability status through authorized distributors as supply may be limited. Ensure compliance with RoHS directives if required by project specifications. Cross-reference datasheet revisions to validate parameter consistency before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a manual reset input is required alongside standard voltage supervision. The low quiescent current makes it suitable for battery-operated applications. Verify that the 3.08 V threshold aligns with the monitored rail. Consider the SOT-143-4 package size constraints during PCB layout planning. Ensure the active high output logic matches the downstream receiver requirements.

Supervisors Part Context

This part belongs to the ADM812 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and package options to suit different monitoring needs. The ADM812 variant specifically distinguishes itself by including a manual reset feature, unlike some other members of the family that may lack this functionality. It serves as a dedicated solution for ensuring reliable system startup and recovery.

Supervisors Replacement Considerations

Check for ADM812 variants with different threshold voltages or package types if physical fitment differs. Verify functional equivalence regarding the manual reset feature and output polarity. Consult Analog Devices documentation for direct cross-references within the same product line.
