Procurement Notes
Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct package and temperature grade. Confirm AEC-Q100 qualification status and functional safety integrity level requirements match your specific design implementation before procurement.
Selection Notes
Select this component when designing systems requiring high channel counts with integrated safety features. Compare output current specifications against similar models like the TLC69638QDCARQ1 if higher drive capability is needed. Ensure the HTSSOP-56 footprint aligns with PCB layout constraints and thermal management strategies.
Part Context
This device belongs to the TLC69628-Q1 series of automotive LED drivers. It is distinct from lower-channel variants such as the TLC69622-Q1 and complements other family members offering different current ratings or local dimming features. The Q1 suffix denotes automotive qualification.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official manufacturer cross-reference lists for verified alternatives.
