TLC69610QPWPRQ1

Overview

The TLC69610QPWPRQ1 is an automotive-grade LED driver IC designed for mini-LED matrix local dimming backlight applications. It functions as an 8-scan MOSFET controller featuring 16 output channels within a 28-pin HTSSOP package. The device operates on a PWM topology with a maximum output current of 60 mA per channel and supports input voltages ranging from 3 V to 5.5 V. It delivers up to 20 V output voltage and utilizes a 20 MHz operating frequency. The component is qualified for extended temperature ranges spanning from -40°C to +125°C, ensuring reliability in automotive environments.

Feature Summary

• Automotive qualification for reliable operation in vehicle environments
• Integrated 8-scan MOSFET control architecture for efficient matrix driving
• Supports local dimming functionality for enhanced display contrast

Applications

• Mini-LED matrix local dimming backlight systems
• Automotive display illumination control
• High-resolution automotive infotainment screens

Procurement Notes

Verify the complete part number including suffixes such as PWPRQ1 to ensure correct packaging and automotive grade specifications. Confirm that the procurement source provides official Texas Instruments documentation or authorized distribution channels. Check for moisture sensitivity labeling and storage conditions prior to assembly. Ensure compatibility with existing PCB footprints and thermal management requirements for the HTSSOP-28 package.

Selection Notes

Select this component when designing automotive displays requiring precise local dimming control via an 8-scan architecture. It is suitable for applications needing 16 independent output channels with 60 mA drive capability. Consider the 20 V output limit and 3 V to 5.5 V input range when defining power supply rails. This driver is appropriate for mini-LED matrices rather than standard high-power LED arrays.

Part Context

This part belongs to the TLC6966x-Q1 series of automotive LED drivers from Texas Instruments. It shares the HTSSOP-28 form factor and core interface protocols with siblings like the TLC69600 and TLC69614. The primary distinction lies in its specific 8-scan configuration optimized for particular mini-LED matrix densities and scan rates required by modern automotive display standards.

Replacement Considerations

Direct substitutes include other members of the TLC6966x-Q1 family such as the TLC69600QPWPRQ1 or TLC69614QPWPRQ1, provided the scan configuration matches the design requirements. Verify pin-to-pin compatibility and electrical parameter alignment before swapping components.
