FEATURES  
2
•
Eight LED Drivers (Each Output Programmable  
At Off, On, Programmable LED Brightness,  
Programmable Group Dimming/Blinking Mixed  
With Individual LED Brightness  
•
•
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  
•
•
Eight Constant-Current Open-Drain Output  
Channels  
•
•
Open-Load/Overtemperature Detection Mode  
to Detect Individual LED Errors  
256-Step (8-Bit) Linear Programmable  
Brightness Per LED Output Varying From Fully  
Off (Default) to Maximum Brightness Using a  
97-kHz PWM Signal  
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)  
•
256-Step Group Brightness Control Allows  
General Dimming (Using a 190-Hz PWM Signal  
From Fully Off to Maximum Brightness  
(Default)  
•
•
Output Current Adjusted Through an External  
Resistor  
Constant Output Current Range: 10 mA to  
120 mA  
•
•
•
256-Step Group Blinking With Frequency  
Programmable From 24 Hz to 10.73 s and Duty  
Cycle From 0% to 99.6%  
•
•
Maximum Output Voltage: 17 V  
25-MHz Internal Oscillator Requires No  
External Components  
1-MHz Fast Mode Plus Compatible I2C Bus  
Interface With 30-mA High Drive Capability on  
SDA Output for Driving High-Capacitive Buses  
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.

DESCRIPTION/ORDERING INFORMATION  
The TLC59108 is an I2C bus controlled 8-bit 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.
