Dual-Channel, Digital Isolators, Enhanced System-Level ESD Reliability ADuM3200/ADuM3201 Data Sheet FEATURES GENERAL DESCRIPTION Enhanced system-level ESD performance per IEC 61000-4-x High temperature operation: 125°C Narrow body, RoHS-compliant, 8-lead SOIC Low power operation 5 V operation 1.7 mA per channel maximum @ 0 Mbps to 2 Mbps 3.7 mA per channel maximum @ 10 Mbps 7.0 mA per channel maximum @ 25 Mbps 3 V operation 1.5 mA per channel maximum @ 0 Mbps to 2 Mbps 2.5 mA per channel maximum @ 10 Mbps 4.7 mA per channel maximum @ 25 Mbps Bidirectional communication 3 V/5 V level translation High data rate: dc to 25 Mbps (NRZ) Precise timing characteristics 3 ns maximum pulse width distortion 3 ns maximum channel-to-channel matching High common-mode transient immunity: >25 kV/μs Safety and regulatory approvals UL recognition: 2500 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 = 560 V peak Qualified for automotive applications The ADuM3200/ADuM32011 are dual-channel, digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices. APPLICATIONS Size-critical multichannel isolation SPI interface/data converter isolation RS-232/RS-422/RS-485 transceiver isolation Digital field bus isolation Hybrid electric vehicles, battery monitor 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 ADuM3200/ADuM3201 isolators provide two independent isolation channels in a variety of channel configurations and data rates (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 ADuM3200W and ADuM3201W are automotive grade versions qualified for 125°C operation. In comparison to the ADuM120x isolators, the ADuM3200/ ADuM3201 isolators contain various circuit and layout changes to provide increased capability relative to system-level IEC 61000-4-x testing (ESD, burst, and surge). The precise capability in these tests for either the ADuM120x or ADuM3200/ ADuM3201 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. 1 Protected by U.S. Patents 5,952,849; 6,873,065; 7,075,329.

C | Page 15 of 20 ADuM3200/ADuM3201 Data Sheet APPLICATION INFORMATION Channel-to-channel matching refers to the maximum amount that the propagation delay differs between channels within a single ADuM3200/ADuM3201 component. PC BOARD LAYOUT The ADuM3200/ADuM3201 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 20 mm. See the AN-1109 Application Note for board layout guidelines. Propagation delay skew refers to the maximum amount that the propagation delay differs between multiple ADuM3200/ ADuM3201 components operating under the same conditions. DC CORRECTNESS AND MAGNETIC FIELD IMMUNITY 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 ADuM3200/ADuM3201 incorporate many enhancements to make ESD reliability less dependent on system design. The enhancements include: ESD protection cells added to all input/output interfaces. Key metal trace resistances reduced using wider geometry and paralleling of lines with vias. The SCR effect inherent in CMOS devices minimized by use of guarding and isolation technique between PMOS and NMOS devices. Areas of high electric field concentration eliminated using 45° corners on metal traces. Supply pin overvoltage prevented with larger ESD clamps between each supply pin and its respective ground. While the ADuM3200/ADuM3201 improve system-level ESD reliability, they are no substitute for a robust system-level design. See the AN-793 Application Note, ESD/Latch-Up Considerations with iCoupler Isolation Products for detailed recommendations on board layout and system-level design. 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. The pulses at the transformer output have an amplitude greater than 1.0 V. The decoder has a sensing threshold at about 0.5 V, therefore 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). N is the number of turns in the receiving coil. rn is the radius of the nth turn in the receiving coil (cm). 50% tPHL 50% 05927-012 tPLH OUTPUT (VOx) The ADuM3200/ADuM3201 are extremely immune to external magnetic fields. The limitation on the ADuM3200/ADuM3201’s magnetic field immunity is set by the condition in which induced voltage in the transformer’s receiving coil 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 ADuM3200/ADuM3201 is examined because it represents the most susceptible mode of operation. V = (−dβ/dt) ∑π rn2, 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 of more than ~1 μs at the input, a periodic set of refresh pulses indicative of the correct input state are sent to ensure dc correctness at the output. If the decoder receives no internal pulses for more than about 5 μs, the input side is assumed to be unpowered or nonfunctional, in which case, the isolator output is forced to a default state (see Table 32 and Table 33) by the watchdog timer circuit. 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 input signal’s timing is preserved. Rev. C | Page 16 of 20 Data Sheet ADuM3200/ADuM3201 Given the geometry of the receiving coil in the ADuM3200/ ADuM3201 and an imposed requirement that the induced voltage is at most 50% of the 0.5 V margin at the decoder, a maximum allowable magnetic field is calculated, as shown in Figure 13. 10 1 0.01 0.001 1k 1M 10k 100k 10M MAGNETIC FIELD FREQUENCY (Hz) 100M Figure 13. Maximum Allowable External Magnetic Flux Density 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. This is about 50% of the sensing threshold and does not cause a faulty output transition. Similarly, if such an event were to occur during a transmitted pulse (and had the worst-case polarity), it would reduce the received pulse from >1.0 V to 0.75 V—still well above the 0.5 V sensing threshold of the decoder. DISTANCE = 1m 100 10 DISTANCE = 100mm 1 DISTANCE = 5mm 0.1 0.01 1k 10k 100k 1M 10M MAGNETIC FIELD FREQUENCY (Hz) 100M 05927-014 0.1 MAXIMUM ALLOWABLE CURRENT (kA) 1000 05927-013 MAXIMUM ALLOWABLE MAGNETIC FLUX DENSITY (kgauss) 100 The preceding magnetic flux density values correspond to specific current magnitudes at given distances away from the ADuM3200/ADuM3201 transformers. Figure 14 expresses these allowable current magnitudes as a function of frequency for selected distances. As seen, the ADuM3200/ADuM3201 are extremely immune and can be affected only by extremely large currents operated at high frequency and very close to the component. For the 1 MHz example, one would have to place a 0.5 kA current 5 mm away from the ADuM3200/ADuM3201 to affect the component’s operation. Figure 14. Maximum Allowable Current for Various Current-to-ADuM3200/ADuM3201 Spacings Note that at combinations of strong magnetic fields and high frequencies, any loops formed by printed circuit board traces could induce sufficiently large error voltages to trigger the threshold of succeeding circuitry. Care should be taken in the layout of such traces to avoid this possibility. Rev. C | Page 17 of 20 ADuM3200/ADuM3201 Data Sheet POWER CONSUMPTION 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. The supply current at a given channel of the ADuM3200/ ADuM3201 isolator is a function of the supply voltage, the channel’s data rate, and the channel’s output load. 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 For each output channel, the supply current is given by f ≤ 0.5fr −3 IDDO = (IDDO (D) + (0.5 × 10 ) × CLVDDO) × (2f − fr) + IDDO (Q) f > 0.5fr where: IDDI (D), IDDO (D) are the input and output dynamic supply currents per channel (mA/Mbps). 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). IDDI (Q), IDDO (Q) are the specified input and output quiescent supply currents (mA). 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 6 provides perchannel input supply currents as a function of data rate. Figure 7 and Figure 8 provide per-channel output supply currents 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 ADuM3200 and ADuM3201 channel configurations. A bipolar ac voltage environment is the most stringent. The goal of a 50-year operating lifetime under the ac bipolar condition determines the Analog Devices recommended maximum working voltage. 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. 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. 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. 05927-015 RATED PEAK VOLTAGE 0V All insulation structures eventually break down when subjected to voltage stress over a sufficiently long period. The rate of insulation degradation depends upon 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 ADuM3200/ ADuM3201. 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. Rev. C | Page 18 of 20 Figure 15.

Unipolar AC Waveform RATED PEAK VOLTAGE 05927-017 IDDO = IDDO (Q) The insulation lifetime of the ADuM3200/ADuM3201 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. 0V Figure 17.
