Supervisors Procurement Notes

Verify the exact suffix and tape/reel specifications against the official Analog Devices datasheet before procurement. Confirm availability status as distribution channels may list limited or discontinued stock. Ensure the ordering part number matches the required threshold voltage variant. Check RoHS compliance documentation for regulatory requirements. Validate package dimensions against PCB footprint designs.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-supervision tasks. Consider the 240 ms reset delay duration relative to system startup timing requirements. Evaluate the 60 uA supply current against total system power budgets. Verify that the SOT-23-3 package fits the available board space. Compare operating temperature limits with environmental conditions.

Supervisors Part Context

This part belongs to the ADM809 series of voltage supervisors from Analog Devices. The series offers various threshold voltages and packages to suit different monitoring needs. The LART suffix indicates specific threshold and packaging characteristics. These devices are commonly used in embedded systems requiring reliable power integrity monitoring without complex configuration.

Supervisors Replacement Considerations

Check for ADM809 variants with identical 4.63 V thresholds and SOT-23-3 packaging. Verify pin compatibility for direct replacement. Review datasheets for matching reset delay and current consumption specs.
