The TLC5943 is a 16-channel, constant-current sink LED driver. Each channel has an individually adjustable, 16-bit pulse width modulation (PWM) grayscale (GS) brightness control with 65,536 steps and a 128-step global brightness control (BC). BC adjusts brightness deviation between LED channels and other LED drivers. GS and BC are accessible via a serial interface. A single external resistor sets the maximum current value of all 16 channels.
