TLC5941-Q1 16-Channel LED Driver

The TLC5941-Q1 device is a 16-channel, constantcurrent sink, LED driver. Each channel has an individually adjustable 4096-step grayscale PWM brightness control and a 64-step constant-current sink (dot correction), which both are accessible via a serial interface. This device features two fault diagnostic circuits. The LED open detection (LOD) indicates a bro.
