Features

  • 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 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

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.
