TLC59116-Q1
SLDS223A – MARCH 2016 – REVISED MARCH 2016
TLC59116-Q1 16-Channel FM+ I²C-Bus Constant-Current LED Sink Driver
1 Features
• 16 LED Drivers (Each Output Programmable at
Off, On, Programmable LED Brightness, or
Programmable Group Dimming and Blinking
Mixed With Individual LED Brightness)
• 16 Constant-Current 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 TLC59116-
Q1 Devices to Be Connected to 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 Same Time in Any Combination
• 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 and Overtemperature Detection Mode
to Detect Individual LED Errors
• Output State Change Programmable on
Acknowledge or Stop Command to Update
Outputs Byte-by-Byte or All at Same Time (Default
to Change on Stop)
• Output Current Adjusted Through an External
Resistor
• Constant Output Current Range: 5-mA to 120-mA
• Maximum Output Voltage: 17 V
• 25-MHz Internal Oscillator Requires No External
Components
• 1-MHz Fast-mode Plus (FMT) 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 and SDA Inputs
• No Glitch on Power-Up
• Active-Low Reset
• Supports Hot Insertion
• Low Standby Current

3 Description
The TLC59116-Q1 is an I²C-Bus controlled 16-
channel LED driver that is optimized for
red/green/blue/amber (RGBA) color mixing and
backlight application. 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%.
