Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Check for moisture sensitivity level requirements during storage and handling. Ensure ordering suffix matches specific reel or cut tape preferences. Validate final part number against official ROHM databases to avoid counterfeit risks.

Selection Notes

Select this component when a fixed 6.0V threshold is required for system supervision. Consider the low quiescent current for battery-operated applications. Verify that the active-low output polarity aligns with the target microcontroller reset input. Ensure the SSOP-3 package fits the available PCB footprint constraints.
