TLC69612YBHR

Overview

The TLC69612YBHR is a Texas Instruments LED lighting driver IC designed for mini-LED matrix local dimming backlight applications. It features 16 output channels with independent pixel-level PWM control, supporting up to 16-bit resolution. The device operates within a supply voltage range of 3 V to 5.5 V and delivers a constant sink current of 60 mA per channel at a maximum output voltage of 20 V. It utilizes a DSBGA-24 package (1.58x2.43 mm) and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports hybrid dimming combining local PWM and phase shift techniques for enhanced visual performance.
• Integrates serial interface for simplified data transmission and control signal management.
• Includes built-in diagnostic capabilities for detecting open and short circuit conditions in LED connections.

Applications

• Mini-LED matrix local dimming backlight systems
• High-resolution display panels requiring pixel-level brightness control
• Professional monitors and televisions utilizing advanced HDR technologies

Procurement Notes

Verify the specific ordering suffix YBHR corresponds to the required tape-and-reel packaging configuration. Confirm that the DSBGA-24 footprint matches the target PCB layout dimensions. Ensure the design accommodates the specified thermal dissipation requirements for continuous operation within the stated temperature range. Cross-reference the latest datasheet revision for any updates to electrical characteristics or pin assignments before finalizing procurement.

Selection Notes

Select this component when a high channel count with precise individual control is necessary for complex backlighting architectures. The 60 mA output capability suits standard mini-LED forward voltage requirements. Consider the serial interface constraints if multiple drivers are cascaded. Evaluate the package size against available board space, as the compact DSBGA form factor demands precise assembly processes.

Part Context

This part belongs to the TLC69611 series of local dimming backlight drivers from Texas Instruments. It shares architectural similarities with other members like the TLC69611, offering robust control for modern display technologies. The series focuses on providing efficient power management alongside detailed grayscale accuracy for premium visual experiences.

Replacement Considerations

Direct substitutes include the TLC69611YBHR, which offers similar functionality but may differ in specific channel configurations or feature sets. Verify compatibility by comparing pinouts, electrical limits, and software control protocols. Alternative options should be evaluated based on availability and specific application constraints regarding channel density and current ratings.
