TLC69661QRTWRQ1

Overview

The TLC69661QRTWRQ1 is an automotive-grade LED lighting driver IC designed for local dimming applications. It features a WQFN-24 package and supports 16 channels with two-wire output type. The device operates on a supply voltage range of 3 V to 5.5 V, delivering a maximum output current of 60 mA per channel. It functions within a temperature range of -40°C to +125°C and utilizes a 20 MHz operating frequency. The component is part of the TLC69664 series and is intended for high system efficiency in automotive backlighting.

Feature Summary

Automotive-grade reliability compliant with functional safety standards
Supports mini-LED matrix local dimming control
Integrated PWM dimming capability for precise brightness adjustment

Applications

Automotive LCD local dimming backlight driver
Mini-LED matrix lighting systems
High-efficiency automotive LED illumination

Procurement Notes

Verify the specific ordering suffix RTWRQ1 matches the required tape-and-reel packaging configuration. Confirm that the WQFN-24 package dimensions align with the target PCB footprint. Ensure the automotive qualification status meets the specific project's functional safety requirements before finalizing the procurement order.

Selection Notes

Select this component when designing automotive displays requiring localized light control. The 16-channel architecture suits mid-size matrix applications. Consider the 60 mA output limit for LED string sizing. The wide operating temperature range ensures stability in harsh vehicle environments without additional thermal management complexity.

Part Context

This device belongs to the Texas Instruments TLC6966x-Q1 family of LED drivers. It shares architectural similarities with the TLC69664QRTWRQ1 but is distinct in its specific channel configuration and marking. The Q1 suffix indicates automotive qualification, differentiating it from standard industrial variants within the broader product line.

Replacement Considerations

The TLC69664QRTWRQ1 serves as a public confirmed substitute within the same series. Verify pin compatibility and software register mapping between the two models before implementation.
