Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation, as design steps (BF, UH, UI) may dictate package variations or pin configurations. Confirm component availability status directly with authorized distributors, as this part number may be subject to end-of-life notices or obsolescence warnings.

Selection Notes

Select this component for brushed DC motor control applications requiring integrated power stages. Ensure the system voltage requirements align with the 5.5 V to 28 V operating range. Verify that the 36 KB flash capacity and 3 KB RAM are sufficient for the intended firmware logic and data storage needs.

Part Context

This component belongs to the MOTIX™ family of embedded power ICs designed for automotive motor control. It combines a microcontroller with power drivers to reduce system complexity. Other variants in the TLE987x series offer different memory sizes or interface options while maintaining software and pin compatibility.

Replacement Considerations

The manufacturer recommends TLE9871QXA20XUMA2 as a replacement for the TLE9871QXA20XUMA1. Verify functional equivalence and package compatibility before substitution.
