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.
