TLC59116FIRHBR

1FEATURES

• 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 Addressed Simultaneously 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

• 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

• Low Standby Current

• 3.3-V or 5-V Supply Voltage

DESCRIPTION/ORDERING INFORMATION

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.

Each LED output can be off, on (no PWM control), set at its individual PWM controller value or at both individual and group PWM controller values. The TLC59116F operates with a supply voltage range of 3 V to 5.5 V and the outputs are 17 V tolerant. LEDs can be directly connected to the TLC59116F device outputs.

Software programmable LED group and three sub call I2C bus addresses allow all or defined groups of TLC59116F devices to respond to a common I2C bus address, allowing for example, all the same color 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.

The software reset (SWRST) call allows the master to perform a reset of the TLC59116F through the I2C bus,identical to the power-on reset (POR) that initializes the registers to their default state causing the outputs to be set high (LED off). This allows an easy and quick way to reconfigure all device registers to the same condition.
