Overview
The TLC69660QRTWRQ1 is an automotive-grade LED lighting driver IC designed for mini-LED matrix local dimming backlight applications. It functions as an 8-scan MOSFET controller with a WQFN-24 package. Key electrical parameters include a supply voltage range of 3 V to 5.5 V, a maximum output voltage of 50 V, and an output current of 60 mA per channel. The device supports a working frequency of 20 MHz and operates within a temperature range of -40°C to +125°C.
Feature Summary
- Automotive qualification compliant for reliable operation in vehicle environments
- Integrated 8-scan architecture optimized for mini-LED matrix control
- Supports local dimming functionality for enhanced backlight performance
Applications
- Mini-LED matrix local dimming backlight systems
- Automotive display backlighting
- High-reliability LED driving circuits
Procurement Notes
Verify the complete part number including suffix RTW to confirm the specific tape-and-reel packaging configuration. Ensure compatibility with automotive grade requirements by checking RoHS status and operating temperature specifications against system design constraints before finalizing procurement.
Selection Notes
Select this component when designing automotive displays requiring precise mini-LED matrix control. The 8-scan capability reduces pin count compared to direct drive solutions. Verify that the 60 mA output current meets the specific LED string requirements and that the 50 V drain-source voltage rating accommodates the total forward voltage of the connected LED array.
Part Context
This device belongs to the TLC69660-Q1 series from Texas Instruments, specialized for automotive LED drivers. It complements other TI solutions like the TLC69639-Q1 but focuses specifically on 8-scan MOSFET control rather than high-channel-count direct drive. The Q1 suffix indicates automotive qualification.
Replacement Considerations
Direct substitutes within the same family may include variants with different scan counts or package options, such as the standard TLC69660 (non-Q1) for non-automotive use. Cross-reference with TLC69629-Q1 if higher channel counts are required instead of scanning architectures.
