Procurement Notes

Verify the specific ordering suffix XUMA1 corresponds to the reel packaging format required for production. Confirm that the design step 'A' meets the necessary quality and reliability criteria for the target automotive application before finalizing procurement plans.

Selection Notes

Select this component when a single-chip solution combining MCU logic and power stage driving is required. Ensure the system voltage remains within the 5.5 V to 27 V functional range. Verify that the integrated H-bridge current capacity aligns with the load requirements of the specific actuator being driven.

Part Context

This part belongs to the MOTIX™ family of embedded power ICs designed for automotive motor control. It consolidates processing, communication, and power stages into a VQFN-48-29 package, reducing external component count compared to discrete solutions.

Replacement Considerations

Consult official Infineon documentation for verified cross-references. Substitutions must match the VQFN-48-29 package and pinout configuration to ensure mechanical compatibility.
