Battery Chargers Procurement Notes

Verify the specific suffix 'A' against the official datasheet to confirm pinout or electrical parameter variations compared to standard versions. Confirm RoHS compliance status through the manufacturer's documentation. Check the lifecycle status as NRND (Not Recommended for New Designs) to assess long-term availability risks before finalizing procurement plans.

Battery Chargers Selection Notes

Select this component when a compact solution integrating both charge management and regulation is required. The DSBGA-25 package suits space-constrained designs. Ensure the application requires the specific integrated features such as the built-in sense resistor and reverse current protection to justify its use over discrete alternatives.
