DESCRIPTION
The TLC59208F is an I2C bus controlled 8-bit 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 TLC59208F 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 TLC59208F device outputs.
Software programmable LED Group and three Sub Call I2C bus addresses allow all or defined groups of
TLC59208F 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.
Three hardware address pins allow up to 64 devices on the same bus (see Table 1).
The software reset (SWRST) Call allows the master to perform a reset of the TLC59208F 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.

DESCRIPTION
The TLC59208F is an I2 C bus controlled 8-bit 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.

FEATURES
• Eight LED Drivers (Each Output Programmable at OFF, ON, Programmable LED Brightness, Programmable Group Dimming/Blinking Mixed With Individual LED Brightness)
• Eight 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%
• 64 Programmable Slave Addresses Using Three Hardware Address Pins
• Four Software Programmable I2C BusAddresses (One LED Group Call Address and Three LED Sub Call Addresses) Allow Groups of Devices to be Simultaneously Addressed Any Combination (For Example, One Register Used for ‘All Call’ so That All the TLC59208Fs on the I2C Bus Can be Simultaneously Addressed and the Second Register Used for Three Different Addresses so That One Third of All Devices on the Bus Can be Simultaneously Addressed)
• 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
