TLC69618QPWPRQ1

Overview

The TLC69618QPWPRQ1 is an automotive-grade LED lighting driver IC designed for 128 mini-LED matrix local dimming backlight applications. It features a 16-channel current sink architecture with a maximum output current of 60 mA per channel. The device operates on a supply voltage range of 3 V to 5.5 V and supports a high-speed daisy chain interface. It is housed in a 28-pin HTSSOP package and functions within a temperature range of -40°C to +125°C, ensuring reliability in demanding automotive environments.

Feature Summary

• Supports 128 mini-LED matrix configurations via cascading capabilities
• Provides precise 60 mA constant current sinking for each of the 16 channels
• Integrates a high-speed serial interface for efficient data transmission
• Complies with AEC-Q100 automotive qualification standards

Applications

• Automotive display local dimming backlights
• Mini-LED matrix illumination systems
• High-resolution automotive infotainment screens
• Digital instrument cluster backlighting

Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape/reel specifications. Confirm that the component meets the necessary AEC-Q100 grade requirements for your target automotive application. Ensure compatibility with the system's voltage levels and thermal management constraints before finalizing procurement decisions.

Selection Notes

Select this component when designing automotive displays requiring localized brightness control for mini-LED arrays. Consider the 16-channel density and 60 mA drive capability relative to the total LED count. Evaluate the HTSSOP package dimensions against available PCB space and ensure the high-speed interface aligns with the host controller's communication protocols.

Part Context

This part belongs to Texas Instruments' family of automotive LED drivers, specifically tailored for complex backlighting solutions. It complements other series members by offering higher channel counts and specialized matrix support. The device addresses industry demands for improved contrast and energy efficiency in modern vehicle interior lighting systems.

Replacement Considerations

Direct substitutes include the TLC69618QRTWRQ1, which offers identical electrical performance but utilizes a WQFN-24 package instead of HTSSOP. Designers must verify footprint compatibility and thermal dissipation characteristics when transitioning between these package variants.
