The TLC5951RHAR from Texas Instruments is a 24-channel constant-current sink LED driver. It features selectable grayscale control with up to 12-bit resolution (4096 steps) and 7-bit dot correction for fine-tuning LED brightness. The device supports three independent grayscale clocks for different color groups and provides 8-bit global brightness control for each group.
With an output current capability of 40 mA per channel, the TLC5951RHAR is suitable for various LED driving applications. It operates with a supply voltage range of 3V to 5.5V and supports LED power supply voltages up to 15V. The driver boasts high accuracy, with channel-to-channel accuracy of ±1.5% and device-to-device accuracy of ±3%. It includes features like LED open and short detection, thermal shutdown, and power good indication.
This LED driver is available in a 40-VQFN Exposed Pad package, designed for surface mounting. Its operating temperature range is -40°C to 85°C. The device supports a data transfer rate of up to 30 MHz, making it efficient for complex display systems. The TLC5951RHAR is well-suited for signage and other display applications where precise and reliable LED illumination is critical.
