Procurement Notes

Verify component authenticity through authorized channels as the part is obsolete. Confirm package integrity and pin alignment against VSOF-5 specifications. Review datasheet revisions for any historical parameter updates. Ensure compatibility with existing PCB footprints before integration into new designs due to end-of-life status.

Selection Notes

Select this component when a fixed 2.6 V threshold with high accuracy is required. Consider the VSOF-5 package size constraints for space-limited designs. Evaluate the programmable delay feature against system startup timing requirements. Compare power consumption characteristics with alternative supervisors if battery life is critical.
