The TLC59108 is an I²C bus controlled 8-bit LED driver that is optimized for red/green/blue/amber (RGBA) color mixing and backlight 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%. 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.

Software programmable LED group and three Sub Call I²C bus addresses allow all or defined groups of TLC59108 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 marquee chasing effect, thus minimizing I2C bus commands. Four hardware address pins allow up to 14 devices on the same bus.

• Eight LED Drivers (Each Output Programmable At Off, On, Programmable LED Brightness, Programmable Group Dimming/Blinking Mixed With Individual LED Brightness
• Eight Constant-Current Output Channels
• 256-Step (8-Bit) Linear Programmable Brightness Per LED Output Varying From Fully Off (Default) to Maximum Brightness Using a 97-kHz PWM Signal
• 256-Step Group Brightness Control Allows General Dimming (Using a 190-Hz PWM Signal From Fully Off to Maximum Brightness (Default)
• 256-Step Group Blinking With Frequency Programmable From 24Hz to 10.73s and Duty Cycle From 0% to 99.6%
• Four Hardware Address Pins Allow 14 TLC59108 Devices to be Connected to the Same I2C Bus
• Four Software-Programmable I2C Bus Addresses (One LED Group Call Address and Three LED Sub Call Addresses) Allow Groups of Devices to be Addressed at the Same Time in Any Combination. For Example, One Register Used for All Call, so That All the TLC59108 Devices on the I2C Bus Can be Addressed at the Same Time, and the Second Register Can be Used for Three Different Addresses so That One-Third of All Devices on the Bus Can be Addressed at the Same Time in a Group.
• Software Enable and Disable for I2C Bus Address
• Software Reset Feature (SWRST Call) Allows Device to be Reset Through I2C Bus
• Up to 14 Possible Hardware-Adjustable Individual I2C Bus Addresses Per Device, So That Each Device Can Be Programmed
• Open-Load/Overtemperature Detection Mode to Detect Individual LED Errors
• Output State Change Programmable on the Acknowledge or the Stop Command to Update Outputs BytebyByte or All at the Same Time (Default to Change on Stop)
