ADM809TARTZ-REEL

Supervisors Overview

The ADM809TARTZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 2.63 V with an accuracy of 1.5%. The device provides a push-pull output type and includes a reset delay time of 240 ms. It functions as a single-input monitor without manual reset or watchdog timer capabilities. The component supports surface mount installation in an SOT-23-3 package and maintains operation across a temperature range from -40 C to +125 C, drawing a working power current of 60 uA.

Supervisors Feature Summary

• Provides voltage supervision for single input monitoring applications

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure compatibility with existing PCB footprints and thermal requirements. Confirm RoHS compliance status through authorized channels before integration into production designs.

Supervisors Selection Notes

Select this component when a precise 2.63 V threshold is required for low-voltage systems. Consider the 240 ms delay and push-pull output for specific timing constraints. Evaluate the SOT-23-3 package size against available board space and thermal dissipation needs for the target application environment.

Supervisors Part Context
