Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific datasheet revision and ordering information directly with Infineon Technologies or authorized distributors. Confirm that the 28-PowerVQFN package dimensions match your PCB layout requirements. Ensure compatibility with the intended input voltage range of 4.5V to 5.5V for the driver supply. Check for any recent product discontinuation notices or lifecycle changes before finalizing procurement plans.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when a compact solution for synchronous rectification is required. The integrated 45A driver reduces external component count compared to discrete solutions. Verify that the application load voltage does not exceed the 15V limit. Consider the thermal performance of the PowerVQFN package for the expected power dissipation levels in the target design.
