ADM811RARTZ-REEL

Supervisors Overview

The ADM811RARTZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features an active low output type with manual reset capability. The device monitors a single input and utilizes a SOT-143-4 package for surface mount installation. Key electrical parameters include a threshold voltage of 2.63 V, a reset delay time of 240 ms, and an accuracy of 1.5%. It functions at a working supply current of 15 uA and supports power dissipation of 200 mW.

Supervisors Feature Summary

• Manual reset functionality allows system recovery from undetected states
• Precision voltage monitoring with high accuracy specifications
• Low power consumption suitable for battery-operated applications

Supervisors Applications

• Microprocessor reset circuits
• Battery-powered system supervision
• Portable electronic devices requiring low quiescent current

Supervisors Procurement Notes

Verify the specific suffix REEL against official Analog Devices documentation to confirm tape and reel packaging configuration. Ensure the part number matches the exact threshold voltage variant required for your design, as the ADM811 series includes multiple voltage options. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a precise 2.63 V threshold is required for voltage supervision. Consider the 240 ms reset delay and active low output polarity during interface design. Evaluate the 15 uA operating current against system power budgets. Verify that the SOT-143-4 package fits the available PCB footprint constraints.

Supervisors Part Context

This component belongs to the ADM811 series of microprocessor supervisory circuits designed by Analog Devices. The series provides reliable voltage monitoring solutions for various digital systems. These devices are engineered to replace older generations of similar supervisory ICs while offering improved performance characteristics across industrial temperature ranges.

Supervisors Replacement Considerations

Check Analog Devices documentation for direct pin-compatible alternatives within the ADM811 family that offer different threshold voltages or reset delays if the 2.63 V specification does not match the target application requirements.
