Application Specific Microcontrollers Procurement Notes

Verify the specific design step (BF, UH, or UI) required for the application, as the ordering suffix determines the physical package type. Confirm that the VQFN-48-31 package aligns with the PCB footprint requirements. Ensure the system voltage remains within the 5.5 V to 28 V functional range during operation.

Application Specific Microcontrollers Selection Notes

Select this component when a highly integrated solution for BLDC motor control is needed. It eliminates external gate drivers and LDO regulators due to the internal charge pump and PMU. Consider the 128 KB flash capacity for complex control algorithms and verify compatibility with the LIN 2.2 network protocol used in the target vehicle architecture.

Application Specific Microcontrollers Part Context

This part belongs to the MOTIX™ TLE987x family of embedded power ICs designed specifically for automotive applications. The 'XUMA2' suffix indicates the BF design step variant packaged in a VQFN-48-31 format. It serves as a complete microcontroller and power stage solution, reducing bill-of-materials count compared to discrete MCU and driver combinations.

Application Specific Microcontrollers Replacement Considerations

Other variants within the TLE9879QXA40 family include XUMA3 (UH step) and XUMA4 (UI step), which utilize different packages such as VQFN-48-37 or VQFN-48-79. These are pin-compatible regarding electrical function but require mechanical footprint adjustments.
