The output channels are grouped into three groups of eight channels. Each channel group has a 256-step global brightness control (BC) function and an individual grayscale clock input.
GS, DC, and BC data are accessible via a serial interface port. DC and BC can be programmed via a dedicated serial interface port.
The TLC5951 device has three error-detection circuits for LED-open detection (LOD), LED-short detection (LSD), and thermal error flag (TEF). LOD detects a broken or disconnected LED, LSD detects a shorted LED, and TEF indicates an overtemperature condition.
