• Supports high-speed serial daisy-chain interface for efficient data transmission
• Integrates constant current sinks capable of delivering up to 60 mA per channel

Applications

• Automotive mini-LED matrix backlight systems
• Local dimming control for vehicle display panels
• High-resolution automotive interior lighting arrays

Procurement Notes

Verify the component's AEC-Q100 qualification status and specific automotive grade designation through official Texas Instruments documentation before integration. Confirm that the WQFN-24 package thermal characteristics align with your PCB layout requirements. Ensure the selected variant matches the required operating temperature range and interface specifications for your target application design.

Selection Notes

Select this driver when designing automotive displays requiring granular local dimming zones. The 16-channel configuration suits smaller matrix areas or serves as a building block for larger cascaded systems. Consider the 20 V output limit and 60 mA current capability when determining LED string configurations. Evaluate the thermal performance of the WQFN-24 package against your system's heat dissipation constraints.

Part Context

This component belongs to the TLC696x2/4/8-Q1 series of 16-channel LED drivers from Texas Instruments. These devices are engineered specifically for automotive backlighting needs, offering robust performance under varying environmental conditions. The series provides scalable solutions for different matrix sizes while maintaining consistent interface protocols and electrical characteristics across variants.

Replacement Considerations

Direct substitutes within the same family include the TLC69618QRTWRQ1 for similar channel counts but potentially different internal configurations. Verify pinout compatibility and electrical parameters against the original datasheet before swapping components. Cross-reference with other automotive-grade LED drivers if specific interface or current requirements differ.
