Overview
The TLC69611RTWR is an automotive-grade LED lighting driver IC from Texas Instruments, designed for mini-LED local dimming backlight applications. It features a WQFN-24 package and operates within a supply voltage range of 3 V to 5.5 V. The device provides sixteen high-precision constant current sinks with a maximum output current of 60 mA and a maximum output voltage of 20 V per channel. It supports a high-speed daisy chain interface and functions at a working frequency of 20 MHz. The component is rated for operation between -40°C and +125°C.
Feature Summary
- Integrates sixteen high-precision constant current sinks for accurate LED control
- Supports high-speed daisy chain interface for efficient data transmission
- Designed specifically for automotive mini-LED local dimming backlight systems
Applications
- Automotive mini-LED local dimming backlight drivers
- High-precision LED matrix control systems
- Automotive display illumination circuits
Procurement Notes
Verify the specific suffix RTWR corresponds to the required tape and reel packaging configuration. Confirm that the automotive qualification level meets the target application's reliability standards. Ensure the WQFN-24 thermal pad soldering process aligns with PCB assembly capabilities. Cross-reference the operating temperature range against the environmental conditions of the final product deployment.
Selection Notes
Select this component when sixteen independent constant current channels are required for local dimming applications. Choose the 60 mA output capability for higher brightness LED arrays compared to lower current variants. Consider the WQFN-24 package for compact board space requirements. Verify compatibility with the system's daisy chain architecture and voltage levels before integration.
Part Context
This part belongs to the TLC696x1 series of 16-channel local dimming backlight LED drivers. It shares architectural similarities with models like the TLC69601 and TLC69614 but differs in output current specifications and automotive grading. The series is optimized for precise current sinking in complex LED matrix configurations used in modern vehicle displays.
