The TLC59116 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%.

• 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 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
• 3.3-V or 5-V Supply Voltage
• 5.5-V Tolerant Inputs
