TLC59208F www.ti.com SCLS715A–MARCH2009–REVISEDNOVEMBER2015 9 Detailed Description 9.1 Overview The TLC59208F is an I2C bus controlled 8-bit LED driver optimized for red, green, blue, or amber (RGBA) colormixing applications. Each LED output has its own 8-bit resolution (256 steps) fixed frequency individual PWMcontrollerthatoperatesat97kHzwithadutycycleadjustablefrom0%to99.6%toallowtheLEDtobeset 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 adjustablefrom0%to99.6%thatcaneitherdimorblinkallLEDswiththesamevalue.

TLC59208F SCLS715A–MARCH2009–REVISEDNOVEMBER2015 www.ti.com Feature Description (continued) 9.3.2 ExternalReset A reset can be accomplished by holding the RESET pin low for a minimum of tW. The TLC59208F registers and I2CstatemachinewillbeheldintheirdefaultstateuntiltheRESETinputisonceagainhigh. Thisinputrequiresapull-upresistortoV ifnoactiveconnectionisused. CC 9.3.3 SoftwareReset The Software Reset Call (SWRST Call) allows all the devices in the I2C bus to be reset to the power-up state value through a specific I2C bus command. To be performed correctly, the I2C bus must be functional and there mustbenodevicehangingthebus. TheSWRSTCallfunctionisdefinedasthefollowing: 1. AStartcommandissentbytheI2Cbusmaster. 2. The reserved SWRST I2C bus address 1001 111 with the R/W bit set to 0 (write) is sent by the I2C bus master. 3. The TLC59208F device(s) acknowledge(s) after seeing the SWRST Call address 1001 0110 (9Eh) only. If theR/Wbitissetto1(read),noacknowledgeisreturnedtotheI2Cbusmaster. 4. Once the SWRST Call address has been sent and acknowledged, the master sends two bytes with two specificvalues(SWRSTdatabyte1andbyte2): (a) Byte1=A5h:theTLC59208Facknowledgesthisvalueonly.Ifbyte1isnotequaltoA5h,theTLC59208F doesnotacknowledgeit. (b) Byte 2 = 5Ah: the TLC59208F acknowledges this value only. If byte 2 is not equal to 5Ah, the TLC59208Fdoesnotacknowledgeit. Ifmorethantwobytesofdataaresent,theTLC59208Fdoesnotacknowledgeanymore. 5. Once the correct two bytes (SWRST data byte 1 and byte 2 only) have been sent and correctly acknowledged, the master sends a Stop command to end the SWRST Call. The TLC59208F then resets to the default value (power-up value) and is ready to be addressed again within the specified bus free time (t ). BUF The I2C bus master may interpret a non-acknowledge from the TLC59208F (at any time) as a SWRST Call Abort. The TLC59208F does not initiate a reset of its registers. This happens only when the format of the Start Callsequenceisnotcorrect. 9.3.4 IndividualBrightnessControlWithGroupDimming/Blinking A 97-kHz fixed frequency signal with programmable duty cycle (8 bits, 256 steps) is used to control individually thebrightnessforeachLED. On top of this signal, one of the following signals can be superimposed (this signal can be applied to the 4 LED outputs): • A lower 190-Hz fixed frequency signal with programmable duty cycle (8 bits, 256 steps) is used to provide a globalbrightnesscontrol. • A programmable frequency signal from 24 Hz to 1/10.73 s (8 bits, 256 steps) is used to provide a global blinkingcontrol. 10 SubmitDocumentationFeedback Copyright©2009–2015,TexasInstrumentsIncorporated ProductFolderLinks:TLC59208F

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 10.1 Application Information 10.1.1 SettingLEDCurrent The LED current is primarily dependent on the supply voltage, the forward voltage of the LED, and the series resistor (R ). In many applications the supply voltage and LED forward voltage cannot be adjusted. Hence, SET R isutilizedtoadjusttheLEDcurrent.Thiscalculationisdiscussedindetailinthetypicalapplicationexample. SET 10.1.2 PWMBrightnessDimming The perceived brightness of the LEDs can be adjusted by use of PWM dimming. For example, an LED driven at 50%dutycyclewillappearlessbrightthanitwouldat100%dutycycle.TheTLC59208Foffersdutycyclecontrol for each individual channel and also offers group duty cycle control.

LEDCurrentvsR SET 11 Power Supply Recommendations TLC59208F operates from a V range of 3 V to 5.5 V. The system will also require a power supply for the CC LEDs. The supply voltage for the LEDs must be greater than the forward voltage of the LED plus the V of the OL channel. 26 SubmitDocumentationFeedback Copyright©2009–2015,TexasInstrumentsIncorporated ProductFolderLinks:TLC59208F

ThetracescarryingpowerthroughtheLEDSshouldbewideenoughtohandlethenecessarycurrent. All LED current passes through the device and into the ground node. There must be a strong connection between the device ground and the circuit board ground. For the RGY package, the thermal pad should be connectedtogroundtohelpdissipateheat. 12.2 Layout Example To power supply A0 V CC A1 SDA To (cid:181)C A2 SCL To (cid:181)C OUT0 RESET To (cid:181)C OUT1 OUT7 OUT2 OUT6 OUT3 OUT5 GND OUT4 Via to GND Figure22.
