DESCRIPTION  
The TLC5943 is a 16-channel, constant current sink  
driver. Each channel is individually adjustable with  
65,536 enhanced spectrum pulse-width modulated  
(PWM) steps controlled by grayscale (GS) data. All  
output drivers are adjustable with 128 constant sink  
current steps at same value controlled by brightness  
control (BC) data. Both GS data and BC data are  
writable via a serial interface port. The maximum  
current value of all 16 channels can be set by a  
single external resistor.  
Auto Data Refresh  
Continuous Base LED Open Detection (LOD):  
–
Detect LED opening and LED short to GND  
during display
