description

The TLC5904 is a constant current driver incorporating shift register, data latch, and constant current circuitry

with current value adjustable and a 256 gray scale display using pulse width control. The output current can be

selected as maximum 80 mA with 16 bits or 120 mA with 8 bits, and the current value of constant current output

can be set by one external resistor. After this device is mounted on a PCB, the brightness deviation between

LED modules (ICs) can be adjusted by 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 the constant current output. Moreover, the device

incorporates watchdog time (WDT) circuitry, which turns the constant current output off when a scan signal is

stopped at 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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
