Procurement Notes
Verify the specific suffix RTWRQ1 to confirm the reel packaging and automotive grade qualification. Ensure the design supports the required 20 MHz operating frequency and thermal management for the WQFN-24 package. Confirm compatibility with the 3 V to 5.5 V input voltage range for the target application environment.
Selection Notes
Select this component for designs requiring 16-channel independent control with integrated current sinking capabilities. It is suitable for applications demanding high efficiency and robust performance in automotive environments. Consider the WQFN-24 footprint and the need for time-multiplexing support when evaluating alternative drivers in the series.
Part Context
This part belongs to the TLC696x2/4/8-Q1 family of 16-channel automotive local dimming backlight LED drivers. It shares functional similarities with models like the TLC69654QRTWRQ1 but differs in specific configuration or channel multiplexing requirements. The Q1 designation indicates compliance with automotive quality standards.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Evaluate cross-model variants within the TLC696x2/4/8-Q1 series for potential functional equivalents based on channel count and package constraints.
