iCoupler® Product Quality and Reliability

Insulation Life vs. Voltage Across the Barrier Lifetime is addressed by the manufacturers. Each material has its own model for long term degradation. The SiO2 fits one curve, the polyimide follows a different curve. This shows that lifetime of each of these technologies is adequate at the voltages of interest. Be careful not to misapply modeling predictions Note Polyimide has vastly better lifetime with unipolar use. 3 orders of magnitude for standard couplers. This means tha they can be used at very high dc voltages. Polyimide Lifetime with 400Vrms is Greater than 50 Years Lifetime at Working Voltage is Extrapolated from Empirical Data Chart is worst case AC bipolar for Polyimide, DC and Unipolar AC is better 7

iCoupler Isolation Capability Against Damaging Transient Voltages Withstand Voltage Waveform Withstand Voltage (VISO) Polyimide is used for Safety Isolation 2.5 kVrms and 5kVrms SiO2 is used for Non-safety Applications 1 kVrms Functional isolation 100% Production Tested 1.2 x VISO for 1 second Surge Voltage Simulates a Lightning Strike or Other High Energy Damaging Event >10kV Surge Required for Reinforced VDE Certification iCoupler Products can meet >10kV and have VDE Reinforced Certification 1 sec 60 sec 1.2 x VISO VISO Surge Voltage Waveform More terms Isolation Rating / High voltage withstand – ability of insulation to stand up to 1 minute of high voltage. Nearly always defined as 50-60hz sine wave. This is used as the primary assembly line test for checking isolation integrity. Allowd to use 120% of rated for 1 second to speed up test. Almost always specified as Vrms, but offten used as peak so both are used. Be careful when comparing RMS and Peak voltages, they are done as AC and it is simply picking off a different number for each. 4000Vpeak is the same as 2800Vrms. Working voltage speced as RMS and used that way. This is the voltage that the part will withstand for perminatn use. Usually ~50 years. This number is tied up with insulation lifetime. Does not include non repetitive transients. Surge, is a test for non repetitive transients different specificatin treat spec it and measure it very differntly This is the common wavefor for line surge. Telecom has a different one Insulation lifetime, how long will it work at the working voltage. Difficult to measure because it takes a very long time to wear out insulation VISOM 90% 50% 10% 1 Pulse / Second 1-2uS 50uS 8

iCoupler Isolation is Not Degraded by ESD iCoupler Isolators Withstand 13.0 kV ESD Level per IEC 61000-4-2 Barrier Subjected to 5 Discharges at 13.0 kV Post-Discharge Resistance Measurement Verification iCoupler ISOLATION BARRIER ESD是否会使磁偶的隔离栅损坏？ 对隔离栅进行5次ESD，分别测试每次ESD后变压器两端的电阻，看是否导通。 如图为我们的测试方法及测试结果，测试方法就是在变压器的两边的地端加ESD电压，进行放电，然后测量电阻值。 iCoupler Under Test RIO Note: Arcing across packages surfaces occurs at voltages greater than 13 kV ESD SOURCE

iCoupler EMI Radiation Below Background Transformers do not generate high emissions Low-level EMI above background at 215 MHz (7 dB µV) and 430 MHz (5 dB µV) Likely due to dispersion on power plane at harmonics of 1 ns data transmission pulses In Practice, most issues are related to PCB design, not transformers iCoupler isolators meet FCC Class A and Class B limits with proper bypassing RF Bands: FM VHF UHF Noise above Background @ 215MHz 430MHz ADuM1201 Emissions Measured @ 1Mbps Input per SAE J1752-3 as Measured via TEM Cell 是否磁偶数据通道的变压器会产生EMI问题？ 变压器本身不会产生EMI。如图为ADuM1201在1Mbps下的频谱图。事实上，PCB设计的不好，会引发更多的问题。 SAEJ1752-3 TEM cell test data for 150kHz to 1GHz EMI for Background and 1Mbps rate shown Small increase from background at 215MHz and 430MHz EMI likely due to harmonics of 1 ns width refresh pulses Increase in EMI from background: only 3dBuV @ 215MHz, 5dBuV @ 430MHz

iCoupler Products are Immune to External Magnetic Fields No magnetic core to concentrate external magnetic fields Magnetic field required to disrupt data transfer requires unrealistic conditions Example: an iCoupler isolator must Be located <5 mm from 500 A at 1 MHz current source Current needed to Disrupt Data Transfer 是否磁偶对磁场敏感。 右图为随磁场频率变化，当在一定距离下，需要多大的电流磁偶才会工作不正常。可见需要很大的电流，所以不需要考虑磁场对磁偶的影响。

iCoupler Isolators Behave Better Outside Specified Limits For Short Width Pulses ADuM1410A supports short width pulses iCoupler interprets a 30ns input pulse correctly ISO7240A cannot support short width pulses Outputs erroneous data INPUT OUTPUT INPUT OUTPUT iCoupler能处理30ns脉宽的信号，而ISO连400ns的信号都无法处理。 12

Comments Use this slide to gauge interest and experience (i.e., how much does the editor know about USB, isolation or iCoupler products?). Note that this product supports 2 of the 3 USB data rates; it does not support High Speed 480 Mbps. 480 Mbps is not needed by most of the market; customers are most interested in 12 Mbps, and 1.5 Mbps is a requirement for USB 2.0. USB 2.0 does not require 480 Mbps. USB signals are 3.3V, but the supply is 5V. USB interfaces need to be able to regulate 5V to 3.3V to handle this. Additionally, our product can be run off of a 3.3V supply if no 5V is available. Low Power, High Temperature and High Transient Immunity are characteristics of all our iCoupler products. We are not providing an ESD rating yet since we don’t know how good it is; it’s at least 8 kV, but it may be higher. We’ll have that information at release. 105°C High Temperature 16-Lead SOIC Wide Body Package Evaluation Boards Available

Direct D+/D- Isolation Fits Easily within System ADuM4160 USB Isolator Direct D+/D- Isolation Fits Easily within System Purpose Compare and contrast how the ADuM4160 can be used to isolate USB. Comments As in the first example, the ADuM4160 fits into the peripheral. No additional components are needed (other than resistors and decoupling capacitors, which are also required in the other approaches). A user can use any USB cable – no special connections required. This solution is 50% smaller than the first example; it saves even more space compared to isolated USB cables. Compare the costs: SIE Solution: > $9 Isolated Cable: > $50 to $200 ADuM4160: < $5 36
