Procurement Notes
Verify the specific suffix RTWR confirms the WQFN-24 packaging and tape-and-reel delivery format. Confirm automotive qualification status (AEC-Q100) if required by your design specifications. Ensure the operating temperature range meets your system's thermal requirements, as this variant supports extended industrial/automotive ranges compared to standard commercial options.
Selection Notes
Select this component when designing automotive displays requiring precise local dimming for 64 mini-LED zones. It is suitable for applications needing a single-channel driver with high voltage compliance up to 50 V. Consider the WQFN-24 footprint for space-constrained PCB layouts. Verify compatibility with your host controller's serial interface requirements before finalizing the bill of materials.
Part Context
This part belongs to the Texas Instruments TLC69664 series, specialized for mini-LED matrix applications. It complements other variants like the TLC69664QRTWRQ1, which shares similar electrical characteristics but may differ in specific automotive qualification levels or packaging details. The series focuses on providing efficient, high-density LED control for modern automotive display technologies.
Replacement Considerations
The TLC69664QRTWRQ1 is a related variant within the same family. Verify if the specific automotive grade or packaging differences between RTWR and QRTWRQ1 align with your procurement needs. No direct cross-manufacturer substitutes are confirmed in public documentation.
