The Texas Instruments TLC5951RHAT is a 24-channel constant-current sink LED driver designed for applications like signage. It provides 12-bit selectable grayscale (GS) control with up to 4096 steps, and 7-bit dot correction (DC) for fine-tuning brightness.
This device operates with a supply voltage range of 3V to 5.5V for VCC and supports LED power-supply voltages up to 15V. It features a data transfer rate of 30 MHz and a grayscale control clock of 33 MHz. The constant-current accuracy is ±1.5% channel-to-channel and ±3% device-to-device. Integrated features include LED open and short detection, thermal shutdown with auto-restart, and a grouped delay to prevent inrush current.
The TLC5951RHAT is available in a 40-VQFN (6x6) surface-mount package. It operates within an ambient temperature range of -40°C to 85°C.
