Combining high speed CMOS and monolithic transformer technology, this isolation component provides outstanding performance characteristics superior to alternatives such as optocoupler devices. APPLICATIONS In comparison to the ADuM1200/ADuM1201 isolator, the ADuM3210/ADuM3211 isolators contain various circuit and layout changes providing increased capability relative to systemlevel IEC 61000-4-x testing (ESD, burst, and surge). The precise capability in these tests for either the ADuM1200/ADuM1201 or ADuM3210/ADuM3211 products is strongly determined by the design and layout of the user’s board or module. For more information, see the AN-793 Application Note, ESD/Latch-Up Considerations with iCoupler Isolation Products. Size-critical multichannel isolation SPI interface/data converter isolation RS-232/RS-422/RS-485 transceiver isolation Digital field bus isolation Gate drive interfaces Hybrid electric vehicles, battery monitor, and motor drive By avoiding the use of LEDs and photodiodes, iCoupler devices remove the design difficulties commonly associated with optocouplers. The typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simple iCoupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with these iCoupler products. Furthermore, iCoupler devices consume one-tenth to one-sixth the power of optocouplers at comparable signal data rates. The ADuM3210/ADuM3211 isolators provide two independent isolation channels in two channel configurations with data rates up to 25 Mbps (see the Ordering Guide). They operate with 3.3 V or 5 V supply voltages on either side, providing compatibility with lower voltage systems, as well as enabling voltage translation functionality across the isolation barrier. The ADuM3210/ADuM3211 isolators have a default output low characteristic in comparison to the ADuM3200/ADuM3201 models, which have a default output high characteristic. The ADuM3210W and ADuM3211W models are automotive grade versions qualified for 125°C operation.

K | Page 16 of 21 Data Sheet ADuM3210/ADuM3211 APPLICATIONS INFORMATION PC BOARD LAYOUT The ADuM3210/ADuM3211 digital isolators require no external interface circuitry for the logic interfaces. Power supply bypassing is strongly recommended at the input and output supply pins. The capacitor value should be between 0.01 µF and 0.1 µF. The total lead length between both ends of the capacitor and the input power supply pin should not exceed 2 mm. See the AN-1109 Application Note for board layout guidelines. SYSTEM-LEVEL ESD CONSIDERATIONS AND ENHANCEMENTS System-level ESD reliability (for example, per IEC 61000-4-x) is highly dependent on system design, which varies widely by application. The ADuM3210/ADuM3211 incorporate many enhancements to make ESD reliability less dependent on system design. The enhancements include • • Although the ADuM3210/ADuM3211 improve system-level ESD reliability, they are no substitute for a robust system-level design. For detailed recommendations on board layout and system-level design, see the AN-793 Application Note, ESD/ Latch-Up Considerations with iCoupler Isolation Products. 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 low output can differ from the propagation delay to a logic high output. The pulses at the transformer output have an amplitude greater than 1.0 V. The decoder has a sensing threshold at approximately 0.5 V, thus establishing a 0.5 V margin in which induced voltages can be tolerated. The voltage induced across the receiving coil is given by where: β is the magnetic flux density (gauss). rn is the radius of the nth turn in the receiving coil (cm). N is the total number of turns in the receiving coil. Given the geometry of the receiving coil in the ADuM3210/ ADuM3211 and an imposed requirement that the induced voltage be, at most, 50% of the 0.5 V margin at the decoder, a maximum allowable magnetic field is calculated as shown in Figure 13. 100 50% tPHL 06866-009 tPLH OUTPUT (VOx) The ADuM3210/ADuM3211 are immune to external magnetic fields. The limitation on the magnetic field immunity of the ADuM3210/ADuM3211 is set by the condition in which induced voltage in the receiving coil of the transformer is sufficiently large to either falsely set or reset the decoder. The following analysis defines the conditions under which this can occur. The 3 V operating condition of the ADuM3210/ADuM3211 is examined because it represents the most susceptible mode of operation. V = (−dβ/dt) ∑ πrn2; n = 1, 2, … , N PROPAGATION DELAY-RELATED PARAMETERS INPUT (VIx) Positive and negative logic transitions at the isolator input cause narrow (~1 ns) pulses to be sent to the decoder via the transformer. The decoder is bistable and is, therefore, either set or reset by the pulses, indicating input logic transitions. In the absence of logic transitions at the input for more than 2 µs, a periodic set of refresh pulses indicative of the correct input state is sent to ensure dc correctness at the output. If the decoder receives no internal pulses for more than approximately 5 µs, the input side is assumed to be unpowered or nonfunctional, and the isolator output is forced to a default state by the watchdog timer circuit (see Table 34 and Table 35). 50% Figure 12. 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-to-channel matching refers to the maximum amount that the propagation delay differs between channels within a single ADuM3210/ADuM3211 component. 10 1 0.1 0.01 0.001 1k 1M 10k 100k 10M MAGNETIC FIELD FREQUENCY (Hz) 100M 06866-010 • ESD protection cells are added to all input/output interfaces. Key metal trace resistances are reduced using wider geometry and paralleling of lines with vias. The SCR effect inherent in CMOS devices is minimized by use of a guarding and isolation technique between the PMOS and NMOS devices. Areas of high electric field concentration are eliminated using 45° corners on metal traces. Supply pin overvoltage is prevented with larger ESD clamps between each supply pin and its respective ground. DC CORRECTNESS AND MAGNETIC FIELD IMMUNITY MAXIMUM ALLOWABLE MAGNETIC FLUX DENSITY (kgauss) • • Propagation delay skew refers to the maximum amount that the propagation delay differs between multiple ADuM3210/ ADuM3211 components operating under the same conditions. Figure 13. Maximum Allowable External Magnetic Flux Density Rev. K | Page 17 of 21 ADuM3210/ADuM3211 Data Sheet For example, at a magnetic field frequency of 1 MHz, the maximum allowable magnetic field of 0.2 kgauss induces a voltage of 0.25 V at the receiving coil. The voltage is approximately 50% of the sensing threshold and does not cause a faulty output transition. Similarly, if such an event occurs during a transmitted pulse (and is of the worst-case polarity), it reduces the received pulse from >1.0 V to 0.75 V, which is still well above the 0.5 V sensing threshold of the decoder. POWER CONSUMPTION The preceding magnetic flux density values correspond to specific current magnitudes at given distances from the ADuM3210/ ADuM3211 transformers. Figure 14 expresses these allowable current magnitudes as a function of frequency for selected distances. As shown in Figure 14, the ADuM3210/ADuM3211 are immune and can be affected only by extremely large currents operated at high frequency very close to the component. For the 1 MHz example, a 0.5 kA current placed 5 mm away from the ADuM3210/ADuM3211 is required to affect the operation of the component. For each output channel, the supply current is given by DISTANCE = 1m 100 10 1 DISTANCE = 5mm 0.1 0.01 1k 10k 100k For each input channel, the supply current is given by IDDI = IDDI(Q) f ≤ 0.5fr IDDI = IDDI(D) × (2f − fr) + IDDI(Q) f > 0.5fr IDDO = IDDO(Q) f ≤ 0.5fr IDDO = (IDDO(D) + (0.5 × 10 ) × CLVDDO) × (2f − fr) + IDDO(Q) f > 0.5fr −3 where: IDDI(D), IDDO(D) are the input and output dynamic supply currents per channel (mA/Mbps). IDDI(Q), IDDO(Q) are the specified input and output quiescent supply currents (mA). CL is the output load capacitance (pF). VDDO is the output supply voltage (V). f is the input logic signal frequency (MHz, half of the input data rate, NRZ signaling). fr is the input stage refresh rate (Mbps). To calculate the total IDD1 and IDD2 supply current, the supply currents for each input and output channel corresponding to IDD1 and IDD2 are calculated and totaled.

Figure 14. Maximum Allowable Current for Various Current-to-ADuM3210/ADuM3211 Spacings Figure 6 provides the input supply currents per channel as a function of data rate. Figure 7 and Figure 8 provide the output supply currents per channel as a function of data rate for an unloaded output condition and for a 15 pF output condition, respectively. Figure 9 through Figure 11 provide total IDD1 and IDD2 supply current as a function of data rate for the ADuM3210 and ADuM3211 channel configurations. Note that at combinations of strong magnetic fields and high frequency, any loops formed by the printed circuit board (PCB) traces can induce error voltages sufficiently large to trigger the thresholds of succeeding circuitry. Care should be taken in the layout of such traces to avoid this possibility. Rev. K | Page 18 of 21 Data Sheet ADuM3210/ADuM3211 The values shown in Table 31 summarize the peak voltage for 50 years of service life for a bipolar ac operating condition and the maximum CSA/VDE approved working voltages. In many cases, the approved working voltage is higher than the 50-year service life voltage. Operation at these high working voltages can lead to shortened insulation life in some cases. Note that the voltage presented in Figure 16 is shown as sinusoidal for illustration purposes only. It is meant to represent any voltage waveform varying between 0 V and some limiting value. The limiting value can be positive or negative, but the voltage cannot cross 0 V. The insulation lifetime of the ADuM3210/ADuM3211 depends on the voltage waveform type imposed across the isolation barrier. The iCoupler insulation structure degrades at different rates depending on whether the waveform is bipolar ac, unipolar ac, or dc. Figure 15, Figure 16, and Figure 17 illustrate these different isolation voltage waveforms. Bipolar ac voltage is the most stringent environment. The goal of a 50-year operating lifetime under the bipolar ac condition determines the maximum working voltage recommended by Analog Devices. RATED PEAK VOLTAGE 06866-012 Analog Devices performs accelerated life testing using voltage levels higher than the rated continuous working voltage. Acceleration factors for several operating conditions are determined. These factors allow calculation of the time to failure at the actual working voltage. Any cross-insulation voltage waveform that does not conform to Figure 16 or Figure 17 should be treated as a bipolar ac waveform, and its peak voltage should be limited to the 50-year lifetime voltage value listed in Table 31. 0V Figure 15. Bipolar AC Waveform RATED PEAK VOLTAGE 06866-013 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. In addition to the testing performed by the regulatory agencies, Analog Devices carries out an extensive set of evaluations to determine the lifetime of the insulation structure within the ADuM3210/ADuM3211. In the case of unipolar ac or dc voltage, the stress on the insulation is significantly lower. This allows operation at higher working voltages while still achieving a 50-year service life. The working voltages listed in Table 31 can be applied while maintaining the 50-year minimum lifetime, provided that the voltage conforms to either the unipolar ac or dc voltage cases. 0V Figure 16.
