Procurement Notes

Verify the specific package variant and tape-and-reel specifications against the official datasheet before procurement. Confirm that the component meets the required AEC-Q101 qualification level for your target application environment. Ensure compatibility with your PCB footprint design, as the QFN-25 package requires precise soldering techniques. Cross-reference the manufacturer's latest documentation to confirm active status and any potential supply chain constraints.

Selection Notes

Select this component when a compact, high-current SPS solution is required for automotive or industrial environments. It is suitable for designs needing integrated monitoring capabilities without external sensing components. Consider its thermal performance and switching frequency limits relative to your converter topology. Ensure the input voltage range aligns with your system's power rail requirements.

Part Context

The FDMF5176 belongs to onsemi's Smart Power Stage family, designed to simplify power stage design by combining power switches and drivers. This integration reduces board space and improves efficiency compared to discrete solutions. It targets applications demanding high reliability and compact form factors, particularly in automotive sectors where space and thermal management are critical constraints.

Replacement Considerations

Consult onsemi's official cross-reference guides for verified substitutes. Ensure any replacement matches the 45A current rating, 25V voltage class, and QFN-25 package dimensions. Verify that alternative devices meet the same AEC-Q101 automotive qualification standards if used in automotive applications.
