16-CHANNEL LED DRIVER WITH DOT CORRECTION AND GRAYSCALE PWM CONTROL  
1
FEATURES  
APPLICATIONS  
Monocolor, Multicolor, Full-Color LED Displays  
LED Signboards  
Display Back-Lighting  
2
Qualified for Automotive Applications  
16 Channels  
12-Bit (4096 Steps) Grayscale PWM Control  
Dot Correction: 6 Bit (64 Steps)  
DESCRIPTION  
Drive Capability (Constant-Current Sink):  
0 mA to 60 mA  
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.  
LED Power Supply Voltage up to 17 V  
VCC = 3.0 V to 5.5 V  
Serial Data Interface  
Controlled In-Rush Current  
30-MHz Data Transfer Rate  
CMOS Level I/O  
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.
