Texas Instruments TLC5941
The TLC5941 is a 16-channel, constant-current sink, LED driver. Each channel has an individually adjustable 4096-step grayscale PWM brightness control and a 64-step constant-current sink (dot correction). The dot correction adjusts the brightness variations between LED channels and other LED drivers.| Part No. | TLC5941 |

DESCRIPTION
Both grayscale control and dot correction are accessible via a serial interface. A single external resistor sets the maximum current value of all 16 channels. The TLC5941 features two error information circuits. The LED open detection (LOD) indicates a broken or disconnected LED at an output terminal. The thermal error flag (TEF) indicates an overtemperature condition. VCC GND SCLK SIN XLAT IREF Max. OUTn VREF Current =1.24V GSCLK BLANK GS Counter CNT 0 Status Information: LOD, TED, D...
