description  
The TLC5905 is a constant current driver that incorporates shift register, data latch, constant current circuitry  
with a current value adjustable and 256 gray scale display that uses pulse width control. The output current can  
beselectedasmaximum80mAwith16bitsor120mAwith8bit. Thecurrentvalueoftheconstantcurrentoutput  
is set by one external resistor. After this device is mounted on a printed-circuit board (PCB), the brightness  
deviation between LED modules (ICs) can be adjusted using an external data input, and the brightness control  
for the panel can be accomplished by the brightness adjustment circuitry. Also, the device incorporates the  
output voltage monitor (OVM) used for LED open detection (LOD) by monitoring constant current output.  
Moreover, the device incorporates watchdog timer (WDT) circuitry, which turns constant current output off when  
the scan signal stops during dynamic scanning operation, and thermal shutdown (TSD) circuitry, which turns  
constant current output off when the junction temperature exceeds the limit.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
