The TLC5971 from Texas Instruments is a versatile 12-channel LED driver designed for applications requiring precise color control and brightness. It offers 16-bit grayscale resolution per channel, enabling 65,536 steps for enhanced spectrum PWM control. The device provides a constant current output capability of up to 60 mA per channel, with typical channel-to-channel accuracy of ±1% and device-to-device accuracy of ±1%.
This LED driver operates with a power-supply voltage range from 3V to 5.5V directly, or from 6V to 17V using its internal 3.3V linear regulator. The LED supply voltage can be up to 17V. It supports a data transfer rate of 20 MHz and includes features like global brightness control, auto display repeat, and thermal shutdown with auto-restart.
The TLC5971 is available in HTSSOP (PWP) and VQFN (RGE) packages. It is suitable for various lighting applications, including RGB LED cluster lamps and displays, where accurate and stable LED current is critical for consistent color and brightness.
Key features include 12 constant-current sink output channels, 16-bit grayscale control, 7-bit global brightness control for each color group, and an operating temperature range of -40°C to +85°C. Unlimited device cascading is also supported for larger display systems.
