16-CHANNEL Fm I2C-BUS CONSTANT-CURRENT LED SINK DRIVER

The TLC59116 is an I 2 C bus controlled 16-channel LED Driver that is optimized for red/green/blue/amber (RGBA) color mixing and backlight application for amusement products. 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%. The individual PWM Controller allows each 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%. The group PWM Controller dims or blinks all LEDs with the same value. Each LED output CAN be off, on (no PWM control), or set at its individual PWM Controller value at both individual and group PWM Controller values. The TLC59116 is one of the first LED controller devices in a new Fast-mode Plus (Fm+) family. Fm+ devices offer higher frequency (up to 1 MHz) and longer, more densely populated bus operation (up to 4000 pF). By Texas Instruments
