Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DFKR-S' corresponds to the DFN4.5X3-14 leadless package with wettable flank technology and tape-and-reel transport media containing 4000 units. Confirm that the component meets the specified green manufacturing criteria, indicating RoHS compatibility and halogen-free status. Ensure the selected variant aligns with the required automated optical inspection capabilities for the chosen package type.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel LIN interface is required for automotive sub-networks. The wide VBAT input range from 5.5 V to 40 V accommodates various vehicle electrical systems. The inclusion of integrated pull-up resistors reduces external component dependency for slave nodes. Verify that the DFN4.5X3-14 package dimensions fit the available board space and thermal requirements for the target application environment.

Drivers, Receivers, Transceivers Part Context

The TPT1022Q belongs to the TPT102xQ series of automotive LIN transceivers manufactured by 3PEAK. This family provides localized interconnect solutions compliant with modern LIN physical layer specifications. The series offers single, dual, and quad channel options to support varying network complexity while maintaining consistent protection features and low-power operational modes across all variants.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other TPT102xQ series members such as the TPT1021Q or TPT1024Q if pin counts differ. Cross-vendor equivalents must be verified against ISO 17987-4 compliance and AEC-Q100 Grade 1 qualification. Ensure substitute components match the 5.5 V to 40 V supply range and ±45 V bus fault tolerance specifications.
