The * marking branded on the component designates DIN VDE V 0884-11 approval.4.0 FUNCTION DESCRIPTIONThe NSi812x is a Dual-channel digital isolator based on a capacitive isolation barrier technique. The digital signal is modulated with RF carrier generated by the internal oscillator at the Transmitter side. Then it is transferred through the capacitive isolation barrier and demodulated at the Receiver side.The NSi812x devices are high reliability dual-channel digital isolator with AEC-Q100 qualified. The NSi812x device is safety certified by UL1577 support several insulation withstand voltages (3.75kV rms , 5kV rms ), while providing high electromagnetic immunity and low emissions at low power consumption. The data rate of the NSi812x is up to 150Mbps, and the common-mode transient immunity (CMTI) is up to 150kV/us. The NSi812x device provides digital channel direction configuration and the default output level configuration when the input power is lost. Wide supply voltage of the NSi812x device support to connect with most digital interface directly, easy to do the level shift. High system level EMC performance enhance reliability and stability of use.The NSi812x has a default output status when VDDIN is unready and VDDOUT is ready as shown in Table 4.1, which helps for diagnosis when power is missing at the transmitter side. The output B follows the same status with the input A within 1us after powering up.C O NF ID EN T IA LCopyright © 2019, NOVOSENSEPage 12 Table 4.1 Output status vs. power statusH Ready Ready H Normal operation.L Ready Ready L XUnreadyReadyL HThe output follows the same status with the input within 60us after input side VDD1 is powered on.X Ready Unready XThe output follows the same status with the input within 60us after output side VDD2 is powered on.5.0 APPLICATION NOTE5.1. PCB LAYOUTThe NSi812x requires a 0.1 µF bypass capacitor between VDD1 and GND1, VDD2 and GND2. The capacitor should beplaced as close as possible to the package. Figure 5.1 to Figure 5.4 show the recommended PCB layout, make sure the space under the chip should keep free from planes, traces, pads and via. To enhance the robustness of a design, the user may also include resistors (50–300 Ω ) in series with the inputs and outputs if the system is excessively noisy. The series resistors also improve the system reliability such as latch-up immunity.The typical output impedance of an isolator driver channel is approximately 50 Ω, ±40%. When driving loads where transmission line effects will be a factor, output pins should be appropriately terminated with controlled impedance PCB traces.Figure5.1 Recommended PCB Layout — Top Layer Figure5.2 Recommended PCB Layout — Bottom LayerFigure5.3 Recommended PCB Layout — Top Layer Figure5.4 Recommended PCB Layout — Bottom Layer5.2.

Agilent 81110A Agilent 81100 Family ofPulse Pattern GeneratorsData Sheet – Version 1.3Flexible Pulses or Patterns for DigitalDesigns – Key Features• Pattern mode on all models from 80 MHz to 660 MHz,including pseudo-random binary sequence• The outputs of dual-channel instruments can be added(analog or EXOR, depending on model)• User-retrofittable channels for most models• Upward compatibility• Individual solutions for frequencies up to 50, 80, 165, 330, 400 and 660 MHz• 100% form/fit compatibilitySignals for testing digital designs and componentsThe Agilent 81101A, 81104A, 81110A and 81130A generate all the standard pulses and digital patterns needed to test current logic technologies (CMOS, TTL, LVDS, ECL, etc.).With the optional second channel on all of the models from 80 MHz to 660 MHz, multi-level and multi-timing signals can be obtained using the internal channel addition feature.• Variable pulse parameters in pattern mode as well as in pulse mode (not on the 81130A)• Synchronously triggerable• Simulation of reflections/distortions• (81104A, 81110A)• Three/four-level codes (81104A, 81110A)Glitch-free timing changesTiming values can now be swept without the danger of misleading pulses ordropouts that could cause measurement errors. (Applies to continuous mode, values < 100 ms, consecutive values between 0.5 and twice the previous value on the 81101A, 81104A, 81110A).Reliable measurementsAll models provide clean, accurate pulses with excellent repeatability, thus contribut-ing to measurement integrity.The Agilent 81110A features self-calibration for more accuracy. It also offers a choice of output modules. The Agilent 81111A 165 MHz 10 V module with variable transitions.Along with the Agilent 81112A 330 MHz 3.8 V module, which has differential out-puts and two selectable transition times.The Agilent 81130A offers a choice of output modules: the Agilent 81131A 400 MHz, 3.8 V module and the Agilent 81132A 660 MHz, 2.5 V module which has complementary outputs.Easy-to-useFeatures such as the clear graphicaldisplay, autoset, help, store/recall, preset TTL/ECL levels, selectable units (such as current/voltage, width/duty-cycle), and load compensation ensure a high level of convenience.Stimulate the device’s environmentToday’s devices can require very complex stimuli. To meet this, the Agilent 81130A can sequence and loop its memory for very deep patterns. RZ (return-to-zero), NRZ (non-return-to- zero) and R1 (return-to-one) formats are available. Digital channel addition allows the generation of signals with two different pulse widths and delays or of data rates up to 1.32 Gbit/s in one single channel.Frequency rangeThe Agilent 81130A is designed and recommended for an operation in the frequency range of 170 kHz to 400/660 MHz. However it can be operated in the extended range down to 1 kHz.Data Sheet 81100 Family of Pulse Pattern Generators21.

LIS8410C
非隔离降压式 LED 驱动控制器
功能描述
启动和供电 LIS8410C 是通过供电电阻从线电压直接启动。通 过典型应用电路可以了解到，当采用这种供电方式 启动时，芯片 VDD 的供电电容首先通过供电电阻由 线电压充电，当其上的电压达到阈值 UVLO(off)后， 芯片启动，并开始输出脉冲驱动内部功率开关，由 于芯片自身的耗电非常少，通过启动电阻供电，便 可使 VDD 电压维持在某一值上，保证 IC 正常工作。
变压器匝数计算 当以上计算，得出L和IPK后，需用到NBS=LIPK来计算 出变压器或电感的最少匝数，N>LIPK/BS；N为变压 器线圈匝数， S为变压器磁芯中柱的截面积(AE值)， B的取值需参考磁芯材质而定，以PC40材质为例，建 议B取值0.28T以下。
最短消磁时间与最长消磁时间 LIS8410C 设置了最短消磁时间和最长消磁时间，当 电感过小或输出电压过高时（输出开路），电感的消 磁时间就有可能小于芯片的最短消磁时间，此时芯片 进入保护状态，系统不断重启；当电感过大或输出电 压过低时（输出短路），电感的消磁时间就有可能大 于芯片的最长消磁时间，此时芯片也会进入保护状态。 因此选取一个合理的电感值非常重要，需要设计者重 点考量。需特别指出，当电源正常工作时，其设计的 最小消磁时间一定不能小于芯片的最小消磁时间，并 且留有足够的余量，否则电源将不能正常工作，由于 该系统架构是降压式，所以输入端整流后的最小直流 电压也一定不能低于输出电压。
过温保护 LIS8410C 集成了过温保护功能，当芯片温度超过 保护阈值后，开关管会关断，进入自动重起保护模 式。当错误条件消失，系统自动恢复正常工作状态。

下图示出了这种芯片的典型应用。

通过典型应用电路可以了解到，当采用这种供电方式启动时，芯片VDD的供电电容首先通过供电电阻R1由线电压充电，当其上的电压达到阈值UVLO(off)后，芯片启动，并开始输出脉冲驱动内部功率开关，由于芯片自身的耗电非常少，通过启动电阻供电，便可使 VDD电压维持在某一值上，保证IC正常工作。
欠压锁定（UVLO）LIS8110内部有一个欠压锁定迟滞比较器，其迟滞曲线如下图所示。
当VDD电压从低于UVLO(on)往上升高到UVLO(off)时，芯片才开始启动；而当VDD电压从高于UVLO(off)往下降低到UVLO(on)时才锁定，因此形成图中所示的迟滞窗口。
软启动LIS8110提供软启动功能。
每次启动之后，芯片从最低工作频率逐渐建立到最终恒流所需的开关频率。
整个软启动过程大约在2mS左右。
软启动可以抑制启动时的电流过冲，以降低LED在启动时承受的应力，从而提升LED的寿命。
另一方面，软启动也能抑制启动时内部MOSFET漏极的电压过冲，从而增加系统可靠性。
振荡器LIS8110有一个振荡频率为2MHz的内部振荡器，其输出的时钟作为系统的同步时钟，芯片开关管ON/OFF的导通周期和这个基本频率的周期成正比。
前沿消隐（LEB）LIS8110内部集成了前沿消隐功能，在开关管打开的前450nS内，由CS引脚感应到的干扰信号被屏蔽。
从而可以很好地抑制开关管导通瞬间CS上的噪声尖峰。
恒流操作LIS8110采用专利的恒流追踪技术，通过采用这种技术，只要输入电流在+-10%的范围内，LIS8110模块都能有效追踪，消除工频纹波。
从而加大了系统设计的容差。
VDD过压保护LIS8110也集成了VDD的过压保护功能，当VDD电压超过保护阈值后， 开关管会关断，进入自动重起保护模式。
当错误条件消失，系统自动恢复正常工作状态。
过温保护LIS8110集成了过温保护功能，当芯片温度超过保护阈值后，开关管会关断，进入自动重起保护模式。
当错误条件消失，系统自动恢复正常工作状态。
Source开路保护LIS8110集成了Source电阻开路保护功能，当系统的Source电阻开路时， 开关管会关断，进入自动重起保护模式。
当错误条件消失，系统自动恢复正常工作状态。
输出开路/短路保护LIS8110集成了对输出开路和短路的保护。
一旦输出开路或短路， 系统会进入自动重起保护模式。
当错误条件消失，系统自动恢复正常工作状态。
应用设计启动电阻的设计LIS8110采用母线电压通过R1直接供电，见典型原理图。
当母线电压比较低时，通过R1提供的能量要能使芯片正常工作，但R1不可取值过小，否则在母线电压较高时，又可能会因为R1流过的电流大于芯片的钳位电流，而导致芯片触发OVP保护。
芯片VDD 的UVLO （On ）保护电压在10V 左右，钳位电压在23V 左右，因此芯片VDD 的正常工作电压建议在11-21V 之间。
R1的取值可参考如下算法：.< R1 <.(K Ω)注意，在允许情况下，R1尽可能取值大点，可减少系统损耗，其中DC 是正常工作时母线电压的最小输入电压，DC 是正常工作时母线电压的最大输入电压。
VDD 供电电容的设计 芯片的耗电较少，选用一颗10nF的电容即可让芯片正常工作，但需要注意的是，由于芯片的最大工作电压可以到20V以上，在选用电容时，尽可能的选用耐压50V的电容，以提高供电的可靠性。
Source 电阻的设计 Source电阻（R3）的设计在系统中显得尤为重要。
它是LIS8110模块能否有效跟随输入电流进行输出的关键参数。
在设计时，首要观察在不带LIS8110模块时，输出电流的中心值，此时由于工频纹波电流非常大，仪器的电流读数会上下摆动，我们只需要取个大概的中心值即可。
然后参考CS的Vth取值，进行计算。
I out =(mA)I out 为输出电流的中心值预估，R3为Source 电阻的取值。
需要注意的是，按R3取值后，LIS8110模块的输出电流与之前预估的I out 可能存在误差，但这个电流却是真实的平均输出电流。
为了使LIS8110模块的输出电流能够最大范围的匹配前级电流，在R3取值一定后，可小范围的对R3进行微调，并确保LIS8110模块都能正常工作，以此获得R3的取值范围，最后在R3范围内取中心值即为最终的R3取值。
当R3取值适当时，前级电流误差在+-10%以内，LIS8110的模块都能很好的进行跟踪，这样有利于电源的批量生产，不会因前级电源的批量一致性，或温升等原因造成输出电流无法跟踪。
CS 滤波网络的选取CS滤波网络由R2和C2组成，通过R2及C2对Source 电阻上的电压进行滤波产生直流电平，为CS脚提供输入信号。
R2与C2的乘积太大，会导致环路相应过慢，开机瞬间过冲严重，且在输出短路时，保护不够及时；乘积太小，又会导致系统不稳定，一般情况下，推荐R2取值1K左右，C2取值200nF 左右，实际调试时，可参考该参数进行调整。
Comp 脚电容选取由于Comp 脚的工作电压不高，选取电容耐压10V以上即可。
该电容（C3）是对前级大电解上的纹波电压进行平滑，对于工频纹波来说，由于频率比较低，因此该电容的取值不可太小，推荐200nF 到1uF 左右。
