TLC59208F
SCLS715A – MARCH 2009 – REVISED NOVEMBER 2015
TLC59208F 8-Bit Fm+ I²C Bus LED Driver
1 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 Bus Addresses
(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
• Up to 64 Possible Hardware Adjustable Individual
I²C Bus Addresses Per Device so That Each
Device Can be Programmed Individually
• Output State Change Programmable on the
Acknowledge or the STOP Command to Update
Outputs Byte-by-Byte or All at the Same Time
(Default to Change on STOP)
• Maximum Output Current: 50 mA
• Maximum Output Voltage: 17 V
• 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 Capacitive Buses
• Internal Power-On Reset

• Noise Filter on SCL/SDA Inputs
• No Glitch on Power Up
• Active-Low Reset (RESET)
• Supports Hot Insertion
• Low Standby Current
• 3.3-V or 5-V Supply Voltage
• 5.5-V Tolerant Inputs
• Packages Offered: 16-Pin Thin Shrink Small-
Outline Package [TSSOP (PW)], 16-Pin Quad
Flatpack No Lead [QFN (RGY)]
• –40°C to 85°C Operation
2 Applications
• Gaming
• Small Signage
• Industrial Equipment
3 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.
