TLC69668QRTWRQ1

Overview

The TLC69668QRTWRQ1 is an automotive-grade LED lighting driver IC designed for mini-LED matrix local dimming backlight applications. It features a WQFN-24 package and supports a supply voltage range of 3 V to 55 V, with an output voltage capability up to 50 V. The device provides sixteen independent channels, each capable of sourcing a constant current of 60 mA. It operates within a temperature range of -40°C to +125°C and utilizes PWM dimming with hybrid control mode.

Feature Summary

• Supports 16-channel constant current sinking for precise mini-LED matrix control
• Integrates hybrid control mode for efficient PWM dimming performance
• Qualified for automotive applications with extended temperature operation

Applications

• Automotive mini-LED matrix local dimming backlight systems
• High-resolution automotive display illumination drivers
• Complex LED lighting control in vehicle interior or exterior modules

Procurement Notes

Verify the specific suffix RTW corresponds to the WQFN-24 package and reel/cut-tape packaging configuration as listed by Texas Instruments. Confirm AEC-Q100 Grade 1 qualification status for the target automotive environment. Ensure the design accommodates the 55 V maximum input voltage and 60 mA per channel current limits. Cross-reference the datasheet revision date to ensure compatibility with latest thermal and electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when designing automotive displays requiring localized dimming with high channel counts. The 60 mA output current suits standard mini-LED forward voltage requirements. The wide input voltage range allows flexibility in system power architecture. Consider the WQFN-24 footprint for PCB layout constraints. Verify that the hybrid control mode meets the specific flicker-free dimming requirements of the application.

Part Context

This part belongs to the TLC69668-Q1 series of 16-channel LED drivers from Texas Instruments. It is specifically engineered for automotive backlighting where local dimming enhances contrast and efficiency. The Q1 suffix indicates automotive qualification. Related parts in the family may offer different channel counts or current ratings but share similar interface and control architectures.

Replacement Considerations

Direct substitutes include other variants within the TLC696xx-Q1 family, such as those with different package options like PWPR. Verify pin-to-pin compatibility and identical electrical characteristics, particularly the 60 mA sink current and 16-channel count. Ensure the replacement maintains the same WQFN-24 form factor if space is constrained.
