description  
The TLC5903 is a constant current driver that incorporates shift register, data latch, and constant current  
circuitry with an adjustable current value and a 256 gray scale display that uses pulse width control. The output  
current can be selected at a maximum of 80 mA with 16 bits or 120 mA with 8 bits. The current value of the  
constant current output is set by one external register. After this device is mounted on a printed-circuit board  
(PCB), the brightness deviation between LEDs (ICs) can be adjusted by using an external data input. The  
brightness control for the panel can be adjusted using the brightness adjustment circuitry. Moreover, the device  
incorporates watchdog timer (WDT) circuitry, which turns the constant current output off when the scan signal  
is stopped during the dynamic scanning operation, and thermal shutdown (TSD) circuitry, which turns the  
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.
