Add To BomTLC59108IPWR General Description
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.
Features

- 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 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 Byte by Byte or All at the Same Time
(Default to Change on Stop) - Constant Output Current Adjusted Through an
External Resistor (10mA to 120mA) - 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 - Internal Power-On Reset
- Noise Filter on SCL/SDA Inputs
- No Glitch on Power Up
- Active-Low Reset
- Supports Hot Insertion
- 3.3-V or 5-V Supply Voltage
