DESCRIPTION  
•
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. 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.

Error Information  
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.
