Page 9 DM13C Constant-Current Output Constant-current value of each output channel is set by an external resistor connected between the REXT pin and GND. Varying the resistor value can adjust the current scale ranging from 5mA to 90mA. The reference voltage of REXT terminal (Vrext) is approximately 1.2V. The output current value is calculated roughly by the following equation: Iout(mA) 5 10 20 30 40 50 60 70 80 90 M 46.4 45.9 45 44.5 44.2 44.3 44.9 43.7 42.3 42.7 16-bit Constant Current LED Driver with Error Detection Version:A.005 未經授權而逕予重製、複製、使用或公開本文件，行為人得被追究侵權之相關民刑事責任 Unauthorized reproduction, duplication, use or disclosure of this document will be deemed as infringement.

Users can get related information about the minimum output voltage above. Serial Data Interface The serial-in data (DAI) will be clocked into 16 bit shift register synchronized on the rising edge of the clock (DCK). The data ‘1’ represents the corresponding current output ‘ON’, while the data ‘0’ stands for ‘OFF’. The data will be transferred into the 16 bit latch synchronized on the rising edge (edge trigger) of the strobe signal (LAT); otherwise, the data will be held. The latch pulse should be sent after the falling edge of the last clock within a frame data. The trigger timing of the serial-out data (DAO) will be shifted out on synchronization to the rising edge of the clock.

Page 11 DM13C outputs are turned off while enable terminal (EN) is kept at high level. And they are active when EN shifts to low. Thermal Shutdown During operation, when the junction temperature of the IC will reach approximately above 180℃, it will cause the driver to shutdown all the outputs. Basically, the IC will cool down and return to the safe operating temperature which is approximately below 110℃. DM13C will restart all the outputs at the same time. Operation in the thermal situation for a long time may cause chip damage permanently. 16-bit Constant Current LED Driver with Error Detection Version:A.005 未經授權而逕予重製、複製、使用或公開本文件，行為人得被追究侵權之相關民刑事責任 Unauthorized reproduction, duplication, use or disclosure of this document will be deemed as infringement. Page 12 DM13C LED Open/Short Detection The result of open/short detection of DM13C could be retrieved from serial-out (DAO) data. It will be identified as a LED open failure when the output is turned on but the output voltage is below 0.3V. And then it will be identified as a LED short failure when the output is turned on but the output voltage is above 1/2 VCC. To set up with the following conditions: (1) the image data written in shift register corresponding to particular output channel is ‘1’; (2) the output enable terminal is activated (EN=‘L’); (3) the rising edge of the latch signal (LAT), DM13C will execute LED open/short detection then renews the results within the corresponding shift register. By using the error message retrieved from serial-out data, system can recognize the status of every LED driven by each channel. For either LED open or short detection, the original image data is written to ‘1’ but ‘0’ is retrieved then a LED failure has occurred. If the image data is written to ‘0’ or the output enable terminal is inactive (EN=‘H’), it will not execute any detection process for the corresponding channel. Therefore, system still retrieves the original image data. Real-time monitor With the above operating principle, system could continuously retrieve LED status from serial-out then compare with the last frame data one by one. Once there is any discrepancy (‘1’Æ‘0’), we can locate which channel is abnormal precisely. Since the process is ongoing and without shifting between image mode and detection mode, it does not interrupt the image data flow and the output display. The ‘real-time monitor’ method is suitable for LED Variable Message Signs (VMS) system. 16-bit Constant Current LED Driver with Error Detection Version:A.005 未經授權而逕予重製、複製、使用或公開本文件，行為人得被追究侵權之相關民刑事責任 Unauthorized reproduction, duplication, use or disclosure of this document will be deemed as infringement. Page 13 DM13C Clocks calculation For large LED display applications, ‘real-time monitor’ could be a heavy loading for system because it needs to compare the retrieved information with a lot of frame data. Therefore, to write the image data of all channels to ‘1’, all failure status will be identified when there will be any ‘0’ retrieved. By calculating the numbers of clock pulses, the locations of abnormal channel could be pointed out easily. The “clocks calculation” method helps to minimize the loading and memory resources of system. Selection of Open/Short Detection The default detection type provided by DM13C is LED open detection after power-on. Users could switch LED open to short detection (or short to open detection) by following timing sequence. There are two alternative options could be selected. The option 1 shows triggering latch pulse when the last clock of the frame data kept at high level. The option 2 shows sending one useless clock pulse which will not shift-in data while the latch signal is kept at high level. useless clock pulse does not shift-in data Open Short or Short Open Timing Diagram of LED Open/Short Detection 16-bit Constant Current LED Driver with Error Detection Version:A.005 未經授權而逕予重製、複製、使用或公開本文件，行為人得被追究侵權之相關民刑事責任 Unauthorized reproduction, duplication, use or disclosure of this document will be deemed as infringement.

Page 15 DM13C Threshold of Short Detection The default threshold voltage for LED short detection of DM13C is 1/2 VCC. One could change the default voltage by switching or setting a new voltage of VLED during short detection is going on. Please see the example below for reference: Note that the VSHORT should be satisfied with the following inequality: The new threshold voltage of short detection will be equivalent to: 16-bit Constant Current LED Driver with Error Detection Version:A.005 未經授權而逕予重製、複製、使用或公開本文件，行為人得被追究侵權之相關民刑事責任 Unauthorized reproduction, duplication, use or disclosure of this document will be deemed as infringement. Page 16 DM13C Outputs Delay Large in-rush currents will occur when the system activates all the outputs at once. To reduce this effect, DM13C is designed to have a constant unit of delay (around 1.5ns) between outputs. The delay for every output goes like this: there is no delay for OUT15 and OUT7, 1 unit of delay for OUT14 and OUT6, 2 units of delay for OUT13 and OUT5 and so on. Global Brightness Control DM13C has no built-in global brightness control feature. In order to obtain a lower resolution of global brightness control effect, two methods could be utilized. One is providing PWM signal synchronized on latch pulse to modulate the output enable terminal (EN pin). The other is to adjust the Rrext value or voltage drop across the external resistor.

Page 17 DM13C Power Dissipation The power dissipation of a semiconductor chip is limited to its package and ambient temperature, in which the device requires the maximum output current calculated for given operating conditions. The maximum allowable power consumption can be calculated by the following equation: Pd(max)(Watt) = Tj(junction temperature)(max)(°C)– Ta(ambient temperature)(°C) Rth(junction-to-air thermal resistance)(°C/Watt) The relationship between power dissipation and operating temperature can be refer to the figure below: Power Dissipation Pd(W) 3.5 Tj(max)=150°C QFN32 3 Rth(QFN32)=40.6°C/Watt TSSOP24 PDIP24 2.5 Rth(TSSOP24)=45°C/Watt Rth(PDIP24)=50.0°C/Watt 2 Rth(SOP24)=79.2°C/Watt SOP24 1.5 Rth(SSOP24)=90.2°C/Watt SSOP24 1 0.5 0 0 20 40 60 80 100 120 140 160 Ambient Temperature Ta(℃) The power consumption of IC can be determined by the following equation and should be less than the maximum allowable power dissipation: 16-bit Constant Current LED Driver with Error Detection Version:A.005 未經授權而逕予重製、複製、使用或公開本文件，行為人得被追究侵權之相關民刑事責任 Unauthorized reproduction, duplication, use or disclosure of this document will be deemed as infringement.
