●The TLC59108F device is an I2C bus controlled 8-bit LED driver optimized for red, green, blue, or amber (RGBA) color-mixing applications. Each LED output has its own 8-bit resolution (256 steps) fixed frequency individual PWM controller that operates at 97 kHz with a duty cycle that is adjustable from 0% to 99.6% to allow the LED to be set to a specific brightness value. An additional 8-bit resolution (256 steps) group PWM controller has both a fixed frequency of 190 Hz and an adjustable frequency between 24 Hz to once every 10.73 seconds with a duty cycle that is adjustable from 0% to 99.6% that is used to either dim or blink all LEDs with the same value.
●Each LED output can be off, on (no PWM control), set at its individual PWM controller value or at both individual and group PWM controller values. The TLC59108F operates with a supply voltage range of 3 V to 5.5 V and the outputs are 17-V tolerant. LEDs can be directly connected to the TLC59108F device outputs.
