Procurement Notes
Verify the manufacturer designation as International Rectifier or Infineon Technologies, as corporate acquisitions may affect labeling. Confirm the specific suffix 'TR' indicates tape and reel packaging. Ensure the component matches the 48-LQFP physical footprint and electrical specifications for the 3V-3.6V supply range before integration into designs.
Selection Notes
Select this component when a single-chip solution for sensorless motor control is required. It is suitable for applications needing integrated power switching and digital interface capabilities. Consider the 48-pin package size and thermal requirements for the target enclosure. Verify compatibility with the specific motor type and voltage levels of the application.
Part Context
This part belongs to the iMOTION and MCE series from International Rectifier. These devices are designed to simplify motor control design by combining analog and digital functions. The series targets cost-sensitive and space-constrained applications in the consumer electronics sector, specifically focusing on efficient and reliable motor management.
Replacement Considerations
The IRMCF171 is a related variant within the same product family. Verify pinout compatibility and functional equivalence before substitution. Check if the specific suffix differences impact packaging or minor electrical characteristics.
