Supervisors Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level requirements before procurement. Check for valid datasheet revisions and ensure the specific suffix matches design specifications. Validate supplier credentials to mitigate counterfeit risks associated with discontinued semiconductor parts.

Supervisors Selection Notes

Select this component when a single-channel supervisor with active high output is required. Ensure the 3.07 V threshold aligns with the target rail voltage. Consider the SOT-23 package constraints and 190 ms reset delay timing. Verify that the 5.5 V maximum supply rating covers the system's peak voltage conditions without exceeding limits.
