Power Management - Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited supply status. Confirm the specific suffix 'ETI+' matches design requirements, as ordering suffixes may indicate packaging variations without altering function. Request original datasheets and certification documents to ensure compliance with RoHS standards and operational specifications before integration into production designs.

Power Management - Specialized Selection Notes

Select this PMIC for designs requiring a single-chip solution for charging and power distribution in space-constrained mobile devices. Ensure the system input voltage remains within the 2.4 V to 5.5 V range. Verify that the thermal performance of the 28-TQFN package suits the application's heat dissipation needs. Consider the integrated charger capabilities if external charging circuitry is undesirable to reduce bill of materials complexity.
