Procurement Notes

Verify the specific ordering suffix XUMA4 against the manufacturer's official documentation to confirm packaging details and tape-and-reel specifications. Ensure compatibility with automotive qualification standards such as AEC-Q100 during the design-in phase. Cross-reference the part number with the latest datasheet revision to confirm availability status and any potential errata updates.

Selection Notes

Select this SoC for applications requiring integrated motor control and LIN communication without external microcontrollers. Compare pinout and peripheral sets with other TLE987x variants if different memory sizes or interface options are required. Verify that the external NFET selection matches the driver capabilities and voltage ratings specified in the application guidelines.

Part Context

This component belongs to the TLE987x product family, which provides scalable motor control solutions. It shares architectural similarities with parts like the TLE9877QXA40XUMA2 but may differ in packaging or specific manufacturing lot attributes defined by the suffix. The MOTIX™ ecosystem offers associated software libraries and reference designs to accelerate development for automotive motor applications.

Replacement Considerations

The TLE9877QXA40XUMA2 is a verified alternative within the same functional family. Confirm pin-to-pin compatibility and identical electrical characteristics before substitution. Review the specific datasheet differences between the XUMA2 and XUMA4 suffixes to ensure no changes in packaging or quality classification affect the design.
