ADuM151N Functional Block Diagram VDD1 1 GENERAL DESCRIPTION The ADuM150N/ADuM151N/ADuM152N1 are 5-channel digital isolators based on Analog Devices, Inc., iCoupler(R) technology. Combining high speed, complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, these isolation components provide 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 4.5 ns at 5 V operation. Channel to channel matching of propagation delay is tight at 4.0 ns maximum. 1 16 Figure 1. ADuM150N Functional Block Diagram APPLICATIONS The ADuM150N/ADuM151N/ADuM152N data channels are independent and are available in a variety of configurations with a withstand voltage rating of 3.0 kV rms (see the Ordering Guide). The devices operate with the supply voltage on either side ranging from 1.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier.

Using an on/off keying (OOK) technique and the differential architecture shown in Figure 16 and Figure 17, the ADuM150N/ADuM151N/ADuM152N have 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 common-mode transient immunity and high immunity to electrical noise and magnetic interference. Radiated emissions are minimized with a spread spectrum OOK carrier and other techniques. Figure 16 shows the waveforms for models of the ADuM150N0/ ADuM151N0/ADuM152N0 that have the condition of the failsafe 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 sets the output to low. For the ADuM150N1/ADuM151N1/ADuM152N1 that have a fail-safe output state of high, Figure 17 illustrates 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 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.

Power supply bypassing is strongly recommended at the input and output supply pins (see Figure 18). Bypass capacitors are connected between Pin 1 and Pin 8 for VDD1 and between Pin 9 and Pin 16 for VDD2. The recommended bypass capacitor value is between 0.01 F and 0.1 F. The total lead length between both ends of the capacitor and the input power supply pin must not exceed 10 mm. Figure 20 shows the eye diagram for the ADuM150N/ ADuM151N/ADuM152N. 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 GSPS with the DPOJET jitter and eye diagram analysis tools. The result shows a typical measurement on the ADuM150N/ADuM151N/ADuM152N with 490 ps p-p jitter. 5 4 VOLTAGE (V) Figure 18. 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. 3 2 1 0 -10 -5 0 5 10 TIME (ns) 14531-020 VDD2 VOA VOB VOC VID/VOD VIE/VOE NIC GND2 14531-018 VDD1 VIA VIB VIC VID/VOD VIE/VOE NIC GND1 Figure 20.

INSULATION LIFETIME PROPAGATION DELAY RELATED PARAMETERS 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. Propagation delay is a parameter that describes the time it takes a logic signal to propagate through a component. The propagation delay to a Logic 0 output may differ from the propagation delay to a Logic 1 output. INPUT (VIx) 50% OUTPUT (VOx) tPHL 14531-019 tPLH 50% Figure 19. 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. Channel matching is the maximum amount the propagation delay differs between channels within a single ADuM150N/ ADuM151N/ADuM152N component. Propagation delay skew is the maximum amount the propagation delay differs between multiple ADuM150N/ADuM151N/ ADuM152N components operating under the same conditions. 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. Surface Tracking 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 ADuM150N/ADuM151N/ADuM152N isolators are presented in Table 9. Rev. 0 | Page 20 of 22 Data Sheet ADuM150N/ADuM151N/ADuM152N Testing and modeling have shown that the primary driver of longterm 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. VRMS = VAC RMS 2 + VDC 2 VAC RMS = VRMS - VDC 2 VDC TIME The working voltage across the barrier from Equation 1 is VRMS = VAC RMS 2 + VDC 2 VRMS = 2402 + 4002 VRMS = 466 V This VRMS value 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. (1) VAC RMS = VRMS 2 - VDC 2 VAC RMS = 4662 - 4002 (2) where: VAC RMS is the time varying portion of the working voltage. VRMS is the total rms working voltage. VDC is the dc offset of the working voltage. VRMS VPEAK Figure 21. Critical Voltage Example or 2 VAC RMS 14531-021 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. The working voltage applicable to tracking is specified in most standards. ISOLATION VOLTAGE Insulation Wear Out VAC RMS = 240 V rms 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. 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 V ac rms and a 400 V dc 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 21 and the following equations. 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.
