Procurement Notes

Verify the specific suffix against official Infineon documentation to confirm pinout and feature variations. Ensure compatibility with automotive environmental standards before integration. Confirm moisture sensitivity levels and reflow soldering profiles during assembly planning. Cross-reference the exact part number with current datasheets to validate interface configurations and memory sizes.

Selection Notes

Select this component for cost-effective brushed DC motor control solutions requiring integrated power stages. Consider the 40 MHz processing speed and limited I/O count for simpler actuator applications. Evaluate the VQFN-48 package constraints for PCB layout. Verify that the LIN interface meets system communication requirements without additional transceivers.

Part Context

This MCU belongs to the TLE984x series within Infineon’s MOTIX portfolio, targeting low-cost automotive actuators. It complements higher-performance variants like the TLE989x by offering simplified integration for relay-based loads. The series emphasizes robustness and compactness for standard 12 V vehicle electrical architectures.

Replacement Considerations
