Battery Chargers Procurement Notes

Verify current availability status as the component is marked NRND (Not Recommended for New Designs). Confirm that existing inventory meets project requirements since new design adoption is discouraged. Check datasheet revisions for any functional updates before integration into final hardware specifications.

Battery Chargers Selection Notes

Select this part only if legacy compatibility or specific automotive certification is required. Evaluate alternative newer generation PMICs for fresh designs due to the NRND status. Ensure system voltage and thermal constraints align with the specified operating range and package capabilities.

Battery Chargers Part Context

This component is part of the LP3921 family of specialized power management ICs. It serves as a dedicated solution for managing battery charging profiles and providing regulated outputs in demanding automotive environments. The SQ designation confirms its compliance with automotive quality standards.

Battery Chargers Replacement Considerations

DS92LV0421SQE/NOPB is listed as a parameter equivalent substitute in some contexts, though functionally distinct. Verify electrical compatibility carefully. No direct pin-to-pin replacement is explicitly confirmed in public data.
