Procurement Notes

Verify the specific ordering suffix XUMA4 corresponds to the UI package variant (VQFN-48-79) as defined in the product validation table. Confirm that the component meets the required automotive qualification standards before integration into safety-critical designs.

Selection Notes

Select this model when an integrated H-bridge driver and LIN communication are required for brushed DC motor control. Ensure the design accommodates the 5.5 V to 28 V supply range and the thermal characteristics of the VQFN-48-79 package for the target application environment.

Part Context

This part belongs to the MOTIX™ family of embedded power ICs designed for automotive actuator drives. It combines a standard MCU with power stages and communication interfaces to reduce system complexity and board space compared to discrete solutions.

Replacement Considerations

The datasheet lists TLE9867QXA40XUMA2 (BF package) and TLE9867QXA40XUMA3 (UH package) as alternative orderable parts for the same functional device. Verify pinout compatibility if substituting between different package types.
