Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify component status as the FDMF301155 is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure compliance with REACH and SVHC regulations before integration. Validate that the PQFN-31 package matches your PCB footprint requirements. Check for any specific handling precautions related to the silicon technology used.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component for designs requiring integrated half-bridge solutions with high peak current capability. The fixed 4.5 V to 5.5 V supply range limits compatibility with higher voltage logic systems without level shifting. Consider the 8 ns switching speed for appropriate dead-time configuration. Evaluate thermal performance within the specified -40°C to +125°C operating range for your enclosure design.
