- 16 LED Drivers (Each Output Programmable at
OFF, ON, LED Brightness, and Group
Dimming/Blinking Mixed With Individual LED
Brightness) - 16 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 Hardware Address Pins Allow 14
TLC59116F 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 AddressedSimultaneously in Any Combination
(For example, One Register Used for ‘All Call’ So
All the TLC59116Fs on the I2C Bus Can be
Addressed at the Same Time and the Second
Register Used for Three Different Addresses So
That 1/3 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 the
Device to be Reset Through the I2C Bus - Up to 14 Possible Hardware Adjustable Individual
I2C Bus Addresses Per Device so That Each
Device Can be Programmed - 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. - 120-mA Maximum Output Current
- 17-V Maximum Output Voltage
- 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 Capacity Buses - Internal Power-On Reset
- Noise Filter on SCL/SDA Inputs
- No Glitch on Power Up
- Active-Low Reset
- Supports Hot Insertion

The TLC59116F is an I2C-bus controlled 16-channel LED driver optimized for red/green/blue/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.
