Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify component status as the FDMF4061 is officially listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market channels. Ensure compatibility with existing PCB footprints and design requirements before procurement. Check for end-of-life notices and potential supply chain constraints associated with discontinued parts.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component for applications requiring a dedicated half-bridge driver with low on-resistance. Consider the 36-PowerWFQFN package size for space-constrained designs. Evaluate thermal performance given the 125°C junction temperature rating. Verify that the 10V to 20V supply range aligns with system power rails. Assess if the 25A output current meets load requirements.

Full Half-Bridge (H Bridge) Drivers Part Context

The FDMF4061 belongs to onsemi's portfolio of power management integrated circuits, specifically within the full-bridge and half-bridge driver category. It is part of the broader SyncFET family, which integrates gate drivers with power MOSFETs to enhance efficiency and reduce component count in power conversion stages.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

As the FDMF4061 is obsolete, identify equivalent half-bridge drivers from onsemi or other manufacturers. Ensure substitute parts match the 36-PowerWFQFN package and electrical specifications. Verify pin-to-pin compatibility to minimize redesign efforts.
