Supervisors Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm the specific suffix W5 corresponds to the SOT-25 package variant. Check current lifecycle status as availability may be restricted or subject to discontinuation notices. Ensure compatibility with existing PCB footprint designs before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.25V threshold is required for voltage monitoring. The SOT-25 package offers space efficiency compared to larger alternatives. Consider the 200ms reset delay for timing-sensitive applications. Verify that the active low output logic aligns with the connected microcontroller or system requirements.

Supervisors Part Context

This part belongs to the APX803L series of micropower voltage detectors from Diodes Incorporated. The series is engineered for low-power applications requiring precise voltage supervision. The APX803L20-23W5-7 specifically denotes the 2.25V threshold variant in the SOT-25 package, distinguishing it from other threshold voltages and package types within the same family.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the APX803L series with different thresholds if voltage requirements change. Verify functional equivalence with other manufacturers' voltage supervisors offering similar 2.25V thresholds and SOT-25 packaging.
