●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%.
●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
●Applications
●• General LED Lighting Applications
●• Backlight for center stack buttons
●• Backlight for cluster indicators
