TLC5916,TLC5917 www.ti.com SLVS695D–JUNE2007–REVISEDJANUARY2015 9 Detailed Description 9.1 Overview The TLC591x is designed for LED displays and LED lighting applications with constant-current control and open- load,shorted-load,andovertemperaturedetection.TheTLC591xcontainsan8-bitshiftregisteranddatalatches, which convert serial input data into parallel output format. At the output stage, eight regulated current ports are designed to provide uniform and constant current for driving LEDs within a wide range of LED Forward Voltage (VF) variations. Used in system design for LED display applications, for example, LED panels, it provides great flexibility and device performance. Users can adjust the output current from 3 mA to 120 mA per channel through anexternalresistor,R ,whichgivesflexibilityincontrollingthelightintensityofLEDs.Thedevicesaredesigned ext for up to 20 V at the output port. The high clock frequency, 30 MHz, also satisfies the system requirements of high-volumedatatransmission. The TLC591x provides two operation modes: Normal Mode and Special Mode. Normal mode is used for shifting LED data into and out of the driver. Special Mode includes two functions: Error Detection and Current Gain Control. The two operation modes include three phases: Normal Mode phase, Mode Switching transition phase, and Special Mode phase. The signal on the multiple function pin OE(ED2) is monitored to determine the mode. When a one-clock-wide pulse appears on OE(ED2), the device enters the Mode Switching phase. At this time, thevoltagelevelonLE(ED1)determineswhichmodetheTLC591xswitchesto. In the Normal Mode phase, the serial data can be transferred into TLC591x through the pin SDI, shifted in the shift register, and transferred out via the pin SDO. LE(ED1) can latch the serial data in the shift register to the outputlatch. OE(ED2)enablestheoutputdriverstosinkcurrent. In the Special Mode phase, the low-voltage-level signal on OE(ED2) can enable output channels and detect the status of the output current to determine if the driving current level is sufficient. The detected Error Status is loaded into the 8-bit shift register and shifted out via the pin SDO, synchronous to the CLK signal. The system controllercanreadtheerrorstatusanddetermineiftheLEDsareproperlylit. In the Special Mode phase, the TLC591x allows users to adjust the output current level by setting a runtime- programmable Configuration Code. The code is sent into the TLC591x through SDI. The positive pulse of LE(ED1) latches the code in the shift register into a built-in 8-bit configuration latch, instead of the output latch. The code affects the voltage at the terminal R-EXT and controls the output-current regulator. The output current can be finely adjusted by a gain ranging from 1/12 to 127/128 in 256 steps. Therefore, the current skew between ICs can be compensated within less than 1%. This feature is suitable for white balancing in LED color display panels.

Normal mode is used for shifting LED data into and out of the driver. Special Mode includes two functions: Error Detection and Current Gain Control. The two operation modes include three phases: Normal Mode phase, Mode Switching transition phase, and Special Mode phase. The signal on the multiple function pin OE(ED2) is monitored to determine the mode. When a one-clock-wide pulse appears on OE(ED2), the device enters the Mode Switching phase. At this time, thevoltagelevelonLE(ED1)determineswhichmodetheTLC591xswitchesto. In the Normal Mode phase, the serial data can be transferred into TLC591x through the pin SDI, shifted in the shift register, and transferred out via the pin SDO. LE(ED1) can latch the serial data in the shift register to the outputlatch.OE(ED2)enablestheoutputdriverstosinkcurrent. In the Special Mode phase, the low-voltage-level signal on OE(ED2) can enable output channels and detect the status of the output current to determine if the driving current level is sufficient. The detected Error Status is loaded into the 8-bit shift register and shifted out via the pin SDO, synchronous to the CLK signal. The system controllercanreadtheerrorstatusanddetermineiftheLEDsareproperlylit. In the Special Mode phase, the TLC591x allows users to adjust the output current level by setting a runtime- programmable Configuration Code. The code is sent into the TLC591x through SDI. The positive pulse of LE(ED1) latches the code in the shift register into a built-in 8-bit configuration latch, instead of the output latch. The code affects the voltage at the terminal R-EXT and controls the output-current regulator. The output current can be finely adjusted by a gain ranging from 1/12 to 127/128 in 256 steps. Therefore, the current skew between ICs can be compensated within less than 1%.

ModeSwitching As shown in Figure 16, once a one-clock-wide short pulse (101) of OE(ED2) appears, TLC591x enters the Mode Switching phase. At the fourth rising edge of CLK, if LE(ED1) is sampled as voltage high, TLC591x switches to Special Mode; otherwise, it switches to Normal Mode. The signal LE(ED1) between the third and the fifth rising edges of CLK cannot latch any data. Its level is used only to determine into which mode to switch. However, the short pulse of OE(ED2) can still enable the output ports. During mode switching, the serial data can still be transferredthroughSDIandshiftedoutfromSDO. NOTE 1. The signal sequenceforthemode switching maybe usedfrequentlyto ensurethatTLC591xis inthepropermode. 2. The 1 and 0 on the LE(ED1) signal are sampled at the rising edge of CLK. The X means its leveldoesnotaffecttheresultofmodeswitchingmechanism. 3. Afterpoweron,thedefaultoperationmodeisNormalMode. 9.4.1.1 NormalModePhase Serial data is transferred into TLC591x through SDI, shifted in the Shift Register, and output via SDO. LE(ED1) can latch the serial data in the Shift Register to the Output Latch. OE(ED2) enables the output drivers to sink current. These functions differ only as described in Operation Mode Switching, in which case, a short pulse triggers TLC591x to switch the operation mode. However, as long as LE(ED1) is high in the Mode Switching phase,TLC591xremainsintheNormalMode,asifnomodeswitchingoccurred. 9.4.1.2 SpecialModePhase In the Special Mode, as long as OE(ED2) is not low, the serial data is shifted to the Shift Register via SDI and shifted out via SDO, as in the Normal Mode. However, there are two differences between the Special Mode and theNormalMode,asshowninthefollowingsections. 9.4.2 ReadingErrorStatusCodeinSpecialMode When OE(ED2) is pulled low while in Special Mode, error detection and load error status codes are loaded into the Shift Register, in addition to enabling output ports to sink current. Figure 17 shows the timing sequence for error detection. The 0 and 1 signal levels are sampled at the rising edge of each CLK. At least three zeros must be sampled at the voltage low signal OE(ED2). Immediately after the second zero is sampled, the data input source of the Shift Register changes to the 8-bit parallel Error Status Code register, instead of from the serial data on SDI. Normally, the error status codes are generated at least 2 μs after the falling edge of OE(ED2). The occurrence of the third or later zero saves the detected error status codes into the Shift Register. Therefore, whenOE(ED2)islow,theserialdatacannotbeshiftedintoTLC591xthroughSDI.When OE(ED2)ispulledhigh, the data input source of the Shift Register is changed back to SDI. At the same time, the output ports are disabled and the error detection is completed. Then, the error status codes saved in the Shift Register can be shifted out via SDO bit by bit along with CLK, as well as the new serial data can be shifted into TLC591x through SDI.

Addendum-Page 1

PACKAGE OPTION ADDENDUM www.ti.com 24-Aug-2018 LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
