5.0 kV rms, Single-Channel Digital Isolator ADuM210N Data Sheet FEATURES GENERAL DESCRIPTION High common-mode transient immunity: 100 kV/μs High robustness to radiated and conducted noise Low propagation delay 13 ns maximum for 5 V operation 15 ns maximum for 1.8 V operation 150 Mbps maximum data rate Safety and regulatory approvals (pending) UL recognition 5000 V rms for 1 minute per UL 1577 CSA Component Acceptance Notice 5A VDE certificate of conformity DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 VIORM = 849 V peak CQC Certification per GB4943.1-2011 Low dynamic power consumption 1.8 V to 5 V level translation High temperature operation: 125°C maximum Fail-safe high or low options 8-lead, RoHS-compliant, SOIC_IC package The ADuM210N1 is a single-channel digital isolator based on Analog Devices, Inc., iCoupler® technology. Combining high speed, complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, this isolation component provides outstanding performance characteristics, superior to alternatives such as optocoupler devices and other integrated couplers. The maximum propagation delay is 13 ns with a pulse width distortion of less than 3 ns at 5 V operation. The ADuM210N supports data rates as high as 150 Mbps with a withstand voltage rating of 5.0 kV rms (see the Ordering Guide). The device operates with the supply voltage on either side ranging from 1.8 V to 5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. Unlike other optocoupler alternatives, dc correctness is ensured in the absence of input logic transitions. Two different fail-safe options are available, in which the outputs transition to a predetermined state when the input power supply is not applied or the inputs are disabled.

With an on/off keying (OOK) technique and the differential architecture shown in Figure 9 and Figure 10, the ADuM210N has very low propagation delay and high speed. Internal regulators and input/output design techniques allow logic and supply voltages over a wide range from 1.7 V to 5.5 V, offering voltage translation of 1.8 V, 2.5 V, 3.3 V, and 5 V logic. The architecture is designed for high commonmode transient immunity and high immunity to electrical noise and magnetic interference. Radiated emissions are minimized with a spread spectrum OOK carrier and other techniques. The ADuM210N digital isolator requires no external interface circuitry for the logic interfaces. Power supply bypassing is strongly recommended at the input and output supply pins (see Figure 8). Bypass capacitors are most conveniently connected between Pin 1 and Pin 4 for VDD1 and between Pin 5 and Pin 8 for VDD2. The recommended bypass capacitor value is between 0.01 μF and 0.1 μF. The total lead length between both ends of the capacitor and the input power supply pin must not exceed 10 mm. Figure 9 shows the waveforms for the ADuM210N0 models, which have the condition of the fail-safe output state equal to low, where the carrier waveform is off when the input state is low. If the input side is off or not operating, the fail-safe output state of low (noted by a 0 in the model number) sets the output to low. For the ADuM210N1 models, which have a fail-safe output state of high, Figure 10 shows the conditions where the carrier waveform is off when the input state is high. When the input side is off or not operating, the fail-safe output state of high (noted by a 1 in the model number) sets the output to high. See the Ordering Guide for the model numbers that have the fail-safe output state of low or the fail-safe output state of high. VDD2 VIA VDD1 GND2 VOA GND1 GND2 13969-005 VDD1 Figure 8. Recommended Printed Circuit Board Layout In applications involving high common-mode transients, ensure that board coupling across the isolation barrier is minimized. Furthermore, design the board layout such that any coupling that does occur equally affects all pins on a given component side. Failure to ensure this can cause voltage differentials between pins exceeding the Absolute Maximum Ratings of the device, thereby leading to latch-up or permanent damage.

The propagation delay to a Logic 0 output may differ from the propagation delay to a Logic 1 output. Surface tracking is addressed in electrical safety standards by setting a minimum surface creepage based on the working voltage, the environmental conditions, and the properties of the insulation material. Safety agencies perform characterization testing on the surface insulation of components that allows the components to be categorized in different material groups. Lower material group ratings are more resistant to surface tracking and, therefore, can provide adequate lifetime with smaller creepage. The minimum creepage for a given working voltage and material group is in each system level standard and is based on the total rms voltage across the isolation, pollution degree, and material group. The material group and creepage for the ADuM210N isolators are presented in Table 9. INPUT (VI) 50% tPHL OUTPUT (VO) 13969-009 tPLH 50% Figure 11. Propagation Delay Parameters Pulse width distortion is the maximum difference between these two propagation delay values and is an indication of how accurately the timing of the input signal is preserved. Propagation delay skew is the maximum amount the propagation delay differs between multiple ADuM210N components operating under the same conditions. JITTER MEASUREMENT Figure 12 shows the eye diagram for the ADuM210N. The measurement was taken using an Agilent 81110A pulse pattern generator at 150 Mbps with pseudorandom bit sequences (PRBS) 2(n − 1), n = 14, for 5 V supplies. Jitter was measured with the Tektronix Model 5104B oscilloscope, 1 GHz, 10 GS/sec with the DPOJET jitter and eye diagram analysis tools. The result shows a typical measurement on the ADuM210N with 380 ps p-p jitter. 5 VOLTAGE (V) 4 2 1 0 TIME (ns) 5 10 13969-010 0 –5 The lifetime of insulation caused by wear out is determined by its thickness, material properties, and the voltage stress applied. It is important to verify that the product lifetime is adequate at the application working voltage. The working voltage supported by an isolator for wear out may not be the same as the working voltage supported for tracking. It is the working voltage applicable to tracking that is specified in most standards. Testing and modeling show that the primary driver of long-term degradation is displacement current in the polyimide insulation causing incremental damage. The stress on the insulation can be broken down into broad categories, such as dc stress, which causes very little wear out because there is no displacement current, and an ac component time varying voltage stress, which causes wear out. The ratings in certification documents are usually based on 60 Hz sinusoidal stress because this reflects isolation from line voltage. However, many practical applications have combinations of 60 Hz ac and dc across the barrier as shown in Equation 1. Because only the ac portion of the stress causes wear out, the equation can be rearranged to solve for the ac rms voltage, as is shown in Equation 2. For insulation wear out with the polyimide materials used in these products, the ac rms voltage determines the product lifetime. 3 –10 Insulation Wear Out VRMS VAC RMS2 VDC2 Figure 12. Eye Diagram INSULATION LIFETIME (1) or All insulation structures eventually break down when subjected to voltage stress over a sufficiently long period. The rate of insulation degradation is dependent on the characteristics of the voltage waveform applied across the insulation as well as on the materials and material interfaces. The two types of insulation degradation of primary interest are breakdown along surfaces exposed to the air and insulation wear out. Surface breakdown is the phenomenon of surface tracking, and the primary determinant of surface creepage requirements in system level standards. Insulation wear out is the phenomenon where charge injection or displacement currents inside the insulation material cause long-term insulation degradation.

Rev. 0 | Page 13 of 15 (2) ADuM210N Data Sheet Calculation and Use of Parameters Example The following example frequently arises in power conversion applications. Assume that the line voltage on one side of the isolation is 240 VAC RMS and a 400 VDC bus voltage is present on the other side of the isolation barrier. The isolator material is polyimide. To establish the critical voltages in determining the creepage, clearance and lifetime of a device, see Figure 13 and the following equations. This is the working voltage used together with the material group and pollution degree when looking up the creepage required by a system standard. To determine if the lifetime is adequate, obtain the time varying portion of the working voltage. To obtain the ac rms voltage, use Equation 2. VAC RMS VRMS 2 – VDC 2 VAC RMS 4662 – 4002 In this case, the ac rms voltage is simply the line voltage of 240 V rms. This calculation is more relevant when the waveform is not sinusoidal. The value is compared to the limits for working voltage in Table 15 for the expected lifetime, less than a 60 Hz sine wave, and it is well within the limit for a 50-year service life. VAC RMS VPEAK VRMS VDC TIME 13969-011 ISOLATION VOLTAGE VAC RMS = 240 V rms Note that the dc working voltage limit in Table 15 is set by the creepage of the package as specified in IEC 60664-1. This value can differ for specific system level standards. Figure 13.
