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 broken or disconnected LED at an output terminal. The thermal error flag (TEF) indicates an over temperature condition. The TLC5941-Q1 features tw...
