TLC5949 Datasheet - Texas Instruments

TLC5949 16-Channel 12-Bit ES-PWM Full Self-Diagnosis LED Driver

The TLC5949 is a 16-channel, constant-current sink LED driver. Each channel has an individuallyadjustable, pulse width modulation (PWM) grayscale (GS) brightness control with 4096 steps. All channels have a 128-step global brightness control (BC). BC adjusts brightness deviation with other LED drive.
