TLC69602QRTWRQ1

Overview

The TLC69602QRTWRQ1 is an automotive-grade LED lighting driver IC designed for 32 mini-LED matrix local dimming applications. It integrates a 16-channel constant current sink with independent PWM control, supporting up to 16-bit resolution per channel. The device operates within a temperature range of -40°C to +125°C and features AEC-Q100 qualification. It utilizes a 24-pin WQFN package (4x4 mm) to facilitate compact PCB layouts in high-density backlighting systems.

Feature Summary

• Provides independent pixel-level PWM control for precise local dimming
• Integrates 16-channel constant current sinks for direct LED driving
• Qualified for automotive environments with extended temperature tolerance
• Supports high-resolution grayscale for enhanced image contrast

Applications

• Automotive display local dimming backlights
• Mini-LED matrix illumination systems
• High-contrast automotive infotainment screens

Procurement Notes

Verify the complete part number including the suffix RTWRQ1 to ensure correct packaging and automotive grade. Confirm that the design supports the specific thermal requirements of the WQFN package. Ensure compatibility with the host controller's communication interface before procurement. Check for any specific ordering restrictions or minimum reel quantities from authorized distributors.

Selection Notes

Select this component when designing automotive displays requiring localized brightness control without external multiplexers. It is suitable for applications needing high channel count density in a small footprint. Consider the 16-bit PWM resolution for smooth gradient rendering. Evaluate the thermal dissipation capabilities of the PCB layout given the integrated current sinks.

Part Context

This device belongs to Texas Instruments' automotive LED driver portfolio, specifically targeting advanced backlighting solutions. It complements other TI components like the LP8872-Q1 by offering dedicated matrix control rather than linear string driving. The Q1 suffix indicates compliance with automotive reliability standards, distinguishing it from general-purpose industrial variants.

Replacement Considerations

Direct substitutes include the TLC69602-Q1 for non-packaged verification or other 16-channel drivers within the same family if pinout compatibility is confirmed. Verify electrical parameters against the TLC69629-Q1 if higher channel counts are acceptable. Always cross-reference datasheets for interface and thermal differences.
