TLC69604QPWPRQ1

Overview

The TLC69604QPWPRQ1 is an automotive-grade LED lighting driver IC designed for local dimming applications in mini-LED matrix backlight systems. It features a single-channel architecture with sixteen integrated constant current sinks, each capable of delivering up to 30 mA. The device operates within a supply voltage range of 3 V to 5.5 V and supports output voltages up to 20 V. It utilizes PWM topology for precise brightness control and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a 28-pin HTSSOP format, it meets AEC-Q100 standards for automotive reliability.

Feature Summary

• Supports 16-channel constant current sinking for high-density mini-LED matrix configurations
• Enables precise local dimming control through integrated PWM dimming capabilities
• Complies with AEC-Q100 automotive qualification standards for harsh environment operation

Applications

• Automotive mini-LED matrix local dimming backlight drivers
• High-resolution LCD backlight control systems
• Advanced automotive display illumination modules

Procurement Notes

Verify the complete part number including the suffix to ensure correct package type and tape/reel configuration. Confirm that the specific variant matches the required thermal performance and electrical specifications for the target application. Cross-reference the datasheet revision to ensure compatibility with existing design implementations and regulatory requirements.

Selection Notes

Select this component when designing automotive displays requiring localized brightness adjustment via mini-LED arrays. The 30 mA sink current suits standard mini-LED forward voltage requirements. Ensure the system design accommodates the 20 V maximum output voltage limit. Consider the HTSSOP-28 footprint for PCB layout constraints and thermal management strategies suitable for the specified operating temperature range.

Part Context

This device belongs to the Texas Instruments TLC6960x series of automotive LED drivers. It shares functional similarities with models like the TLC69614QPWPRQ1 but differs in output current ratings and specific channel configurations. The series is engineered specifically for complex backlighting architectures in modern vehicle infotainment and instrument cluster displays.

Replacement Considerations

Direct substitutes include other members of the TLC6960x family such as the TLC69614QPWPRQ1 or TLC69600QPWPRQ1, provided the pinout and electrical parameters align with the design requirements. Verify channel counts and current sink capabilities before swapping.
