7. 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

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 Vpeak 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

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。

10. 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 215MHz 430MHz
ADuM1201 Emissions 1Mbps Input per SAE J 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。
SAEJ 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 215MHz, 430MHz

11. 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。

12. 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

Purpose
This is an overview of the product features, pricing and availability.
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.

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

Industry’s First Signal and Power Isolated CAN Transceivers in a Single-Package
Purpose
Title slide.

48. ADM3052/ 53 - Industrial Applications Primary Purpose
Electrically Isolate the Controller Area Network Communication Links in Industrial Automation Control and Instrumentation
Protect equipment from damaging surges/spikes
Eliminate down time when using non-isolated ports
Safety certification required (i.e., UL, CSA, VDE, etc.)
Key Difference between ADM3052 & ADM3053
How the power supply is configured
ADM3052 – 4 wire bus configuration with 24V power over the bus
ADM3053 – 2 wire bus configuration with power from logic side of device.
Customer Benefits
Ease-of-use
Reduce design time, reducing Time-to-Market
Small Form Factor
Component Insulation Certified
Lower power consumption than opto’s (7x to 10x)
Purpose
Provide an overview for why isolation is used in industrial systems, key difference between the ADM3052 and ADM3053 and the key customer benefits.
Notes:
Key difference between the ADM3052 and ADM3053 is how the power is configured:
ADM3052 is for the four-wire bus configuration, where 24V power is provided with CAN_H & CAN_L over the bus.
ADM3053 is for the two-wire bus configuration, where power is provide from the logic side of isolation barrier. The isolated DC/DC converter is integrated to provide power to the bus-side circuitry.

UL recognition: 5000 VRMS for 1 minute per UL 1577
VDE Certificates of Conformity
DIN VVDE V (VDE V ):
VIORM = 848 V peak
Key difference between the ADM3052 and ADM3053 is how the power is configured, and isolation maintained:
ADM3052 is for the four-wire bus configuration, where 24V power is provided with CAN_H & CAN_L over the bus.
ADM3053 is for the two-wire bus configuration, where power is provided from the logic side of isolation barrier. The isolated DC/DC converter is integrated to provide power to the bus-side circuitry.

51. Method for Isolating Controller Area Network
24V Power Provided over the Bus – ADM3052
Purpose
Show the discrete implementation of a bus-powered CAN node, which can now be replaced with a single chip.
Comments
CAN Transceiver, 24V regulator and the signal isolation is now all integrated into a single package.
Power is provided to the logic side from the local supply, while power is provided to the bus-side circuitry from the 24V bus power supply.
Signal Isolation channels; 24V LDO and CAN Transceiver all integrated in one package.
70% reduction in component count 51

52. Method for Isolating Controller Area Network
Power provided from Logic Side Only – ADM3053
Purpose
Show the discrete implementation of a single supply isolated CAN node, which can now be replaced with a single chip.
Comments
CAN Transceiver, isoPower DC/DC converter and the iCoupler signal isolation is now all integrated into a single package.
Power is provided from the local supply, the isoPower DC/DC converter provides isolated power to the bus side circuitry.
Signal Isolation channels; isoPower isolated DC/DC Converter and CAN Transceiver all integrated in one package.
80% reduction in component count 52
