Battery Chargers Procurement Notes

Verify the specific suffix 'APUCX' against the official onsemi datasheet to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint and reflow profile requirements. Cross-reference the part number with the manufacturer's latest release notes to check for any recent design changes or obsolescence notices before finalizing procurement.

Battery Chargers Selection Notes

Select this component when a dual-input charging solution with integrated power path management is required for single-cell Li-Ion applications. It is suitable for designs needing USB-OTG boost capabilities alongside standard charging functions. Consider the thermal performance and inductor selection based on the target charging current and input voltage range specified in the datasheet.

Battery Chargers Part Context

The FAN54511 belongs to onsemi's family of USB-compliant single-cell lithium-ion switching chargers. It is part of the broader FAN54 series, which includes various models tailored for different current ratings and feature sets. This specific model emphasizes dual-input flexibility and OTG support, distinguishing it from single-input variants within the same product line.

Battery Chargers Replacement Considerations

Check for direct pin-to-pin replacements within the FAN54 series, such as the FAN54005, ensuring functional equivalence regarding input configuration and current ratings. Verify that alternative parts meet the same electrical specifications and package dimensions to avoid redesign efforts.
