TLC5946PWPR
The TLC5946 is a 16-channel constant-current LED driver with 12-bit PWM grayscale dimming and 6-bit dot correction per channel. It includes fault detection (LED open and short-to-ground/VLED), an error flag and power-good, with a 30 MHz typical data rate, operating from -40 to 85 C. It is used in LED displays and dynamic lighting.
