ADM809JARTZ-REEL

Supervisors Overview

The ADM809JARTZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply integrity in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 4 V with an accuracy of 1.5%. The device provides a push-pull output and includes a reset delay time of 240 ms. It functions without manual reset, watchdog timer, or battery backup switching capabilities. The component draws a typical operating supply current of 60 uA and supports an overvoltage threshold of 4.06 V. It is housed in an SOT-23-3 package suitable for surface mount installation and operates across a temperature range from -40 C to +125 C.

Supervisors Procurement Notes

Verify the exact suffix REEL7 against the specific datasheet revision to confirm packaging details and tape-and-reel specifications. Ensure the 4 V threshold aligns with the target supply rail requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Validate thermal performance within the specified -40 C to +125 C operating range for the intended application environment.

Supervisors Selection Notes

Select this component when a fixed 4 V supervision threshold is required for single-input monitoring. The SOT-23-3 package offers space efficiency for compact designs. Consider the 240 ms delay duration to match system startup timing requirements. Evaluate the 60 uA quiescent current against total system power budgets. Ensure compatibility with push-pull output interfaces used in the target microcontroller or logic family.
