DESCRIPTION  
•
The TLC5940 is a 16-channel constant-current sink  
LED driver. Each channel has an individually adjust-  
able 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. The  
dot correction data is stored in an integrated  
EEPROM. 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 TLC5940 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 con-  
dition.
