SLDS162B – MARCH 2009 – REVISED DECEMBER 2015
TLC59108F 8-Bit FM+ I2C Bus LED Driver
1 Features
1 Eight LED Drivers (Each Output Programmable at
OFF, ON, Programmable LED Brightness,
Programmable Group Dimming and Blinking
Mixed With Individual LED Brightness)
• Eight Open-Drain 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 24 Hz to 10.73 s and Duty
Cycle From 0% to 99.6%
• Four Software Programmable I2C Bus Addresses
(One LED Group Call Address and Three LED
Sub Call Addresses) Allow Groups of Devices to
be Simultaneously Addressed Any Combination
(For Example, One Register Used for All Call so
That All the TLC59108Fs on the I2C Bus Can be
Simultaneously Addressed and the Second
Register Used for Three Different Addresses so
That One Third of All Devices on the Bus Can be
Simultaneously Addressed)
• Software Enable and Disable for I2C Bus Address
• Software Reset Feature (SWRST Call) Allows the
Device to be Reset Through the I2C Bus
• Up to 14 Hardware Selectable I2C Bus Addresses
so That Each Device Can be Programmed
Individually
• Output State Change Programmable on the
Acknowledge or the STOP Command to Update
Outputs Byte-by-Byte or All at the Same Time
(Default to Change on STOP)
• Maximum Output Current: 120 mA
• Maximum Output Voltage: 17 V
• 25-MHz Internal Oscillator Requires No External
Components
• 1-MHz Fast-Mode Plus (FM+) Compatible I2C Bus
Interface With 30 mA High Drive Capability on
SDA Output for Driving High Capacitive Buses
• Internal Power-On Reset
• Noise Filter on SCL/SDA Inputs
• No Glitch on Power Up
• Active-Low Reset (RESET)
• Supports Hot Insertion

2 Applications
• Gaming
• Small Signage
• Industrial Equipment
3 Description
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.
