DESCRIPTION  
The TLC5928 is a 16-channel, constant current sink  
LED driver. Each channel can be turned on/off by  
writing serial data to an internal register. The constant  
current value of all 16 channels is set by a single  
external resistor.

The TLC5928 has two error detection circuits: one for  
LED open detection (LOD) and one for a pre-thermal  
warning (PTW). LOD detects
