|Description||16-Channel Fm+ I2C Bus Constant-Current LED Sink Driver
The TLC59116 is an I2C 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.

The an I2C 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 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 190 Hz and an adjustable frequency between Hz to once every 10.73 seconds, with a duty cycle that is adjustable from 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).

PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of the Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.
Software programmable LED group and three Sub Call I2C bus addresses allow all or defined groups of TLC59116 devices to respond to a common I2C bus address allowing, for example, all red LEDs to be turned on or off at the same time or a marquee chasing effect, thus minimizing I2C bus commands. Four hardware address pins allow to 14 devices on the same bus. The Software Reset (SWRST) call allows the master to perform a reset of the TLC59116 through the I2C bus, identical to the Power-On Reset (POR) that initializes the registers to their default state, causing the outputs to be set high (LED off). This allows an easy and quick way to reconfigure all device registers to the same condition. ORDERING INFORMATION (1)
