Supervisors Procurement Notes

Verify the specific suffix requirements for the ADM809 series, as variations exist between ARTZ and LAKSZ packages. Confirm that the target application supports the SC-70-3 form factor. Check official Analog Devices documentation for the most current lifecycle status, as this part may be classified as obsolete or restricted in certain regions. Ensure compatibility with the required threshold voltage before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for system supervision. Consider the SC-70-3 package size constraints against available board space. Evaluate the 240 ms reset delay against system startup timing requirements. Compare the 60 uA current draw against total system power budgets. Verify that the 1.5 % accuracy meets the precision needs of the monitored rail.

Supervisors Part Context

This part belongs to the ADM809 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and package options including SOT-23 and SC-70. These devices are designed for reliable operation in industrial and commercial environments. The LAKSZ suffix indicates a specific threshold and packaging configuration within the broader family.

Supervisors Replacement Considerations

Public confirmed substitutes include the ADM6326-31ARTZ-R7. Verify pinout compatibility and electrical parameter alignment before substitution.
