Procurement Notes
Verify the specific ordering suffix against the manufacturer's current product selection guide to ensure package availability and revision status. Confirm that the component meets AEC-Q100 qualification requirements for the intended automotive environment before finalizing procurement specifications.
Selection Notes
Select this model for applications requiring integrated motor control logic with direct switching capabilities. Ensure the design accommodates the 3.0 V to 28 V input range and utilizes the internal 5 V regulator if powering external sensors like hall effect devices. Verify pin compatibility with the target VQFN-48 package variant.
Part Context
This component belongs to the Infineon MOTIX™ TLE984xQX series, designed specifically for embedded power applications in vehicles. It combines processing, communication, and power driving functions into a single chip to reduce system complexity and board space compared to discrete solutions.
Replacement Considerations
Consult the official Infineon product selection guide for verified cross-references within the TLE984xQX family. Substitutions must match the required memory size, switch configuration, and package type.
