Overview
The TLC69654QPWPRQ1 is an automotive-grade LED driver featuring 16 constant current sink channels. It supports time-multiplexing for local dimming applications in backlight systems. The device integrates a daisy-chain interface operating at 20 MHz for high-speed data transfer. Each channel provides precise current control with an output capability of 30 mA and can withstand up to 50 V. It utilizes a 28-pin HTSSOP package with an exposed thermal pad for efficient heat dissipation.
Feature Summary
- Provides 16-channel constant current sinking for precise LED matrix management
- Supports time-multiplexing architecture for efficient local dimming control
- Features a high-speed 20 MHz daisy-chain serial interface for seamless integration
Applications
- Automotive LCD backlight systems requiring local dimming
- LED matrix lighting drivers in vehicle instrument clusters
- High-efficiency automotive display illumination modules
Procurement Notes
Verify the complete part number including suffixes such as PWPRQ1 to ensure correct packaging and automotive qualification. Confirm that the specific revision matches the design requirements for thermal performance and electrical characteristics. Cross-reference the datasheet version to ensure compatibility with existing firmware or control logic implementations.
Selection Notes
Select this component when designing automotive displays that require independent channel control for local dimming features. Ensure the system voltage does not exceed the 50 V rating per channel. Verify that the host controller supports the required 20 MHz daisy-chain protocol. Consider the thermal pad requirement for proper PCB layout to maintain reliability under continuous operation.
Part Context
This device belongs to the TLC696x-Q1 family, which includes variants with different channel counts and multiplexing configurations. These components are specifically engineered for automotive environments, meeting stringent reliability standards. The series offers scalable solutions for various display sizes and complexity levels within vehicle interior lighting architectures.
Replacement Considerations
Direct substitutes include other members of the TLC696x-Q1 family, such as the TLC6962QPWPRQ1 or TLC69668QPWPRQ1, depending on the required channel count and multiplexing configuration. Verify pinout compatibility before substitution to ensure seamless integration without PCB redesign.
