Battery Chargers Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor assets were acquired by Texas Instruments. Confirm the specific suffix (e.g., NOPB) and package type (SOT-23-5) match your design requirements. Ensure the component meets current RoHS standards if applicable to your project specifications.

Battery Chargers Selection Notes

Select this component when a dedicated charge controller for lithium cells is required in a small footprint. Consider the SOT-23-5 package constraints for PCB layout. Verify compatibility with the specific lithium battery chemistry and voltage levels intended for the application before finalizing the bill of materials.

Battery Chargers Part Context

This component belongs to the LM3420 series of battery charge controllers. It is functionally related to variants such as the LM3420M5X-8.2 and LM3420-16.8. These devices share similar core functionalities but may differ in specific electrical parameters or pin configurations depending on the exact model suffix and manufacturer revision.

Battery Chargers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with LM3420M5X-8.2 or LM3420-16.8 only after verifying detailed electrical parameter equivalence through official datasheets.
