Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives, such as optocoupler devices. APPLICATIONS General-purpose multichannel isolation SPI interface/data converter isolation RS-232/RS-422/RS-485 transceivers Industrial field bus isolation iCoupler devices remove the design difficulties commonly associated with optocouplers. 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 ADuM3300/ADuM3301 isolators provide three independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). All models operate with the supply voltage on either side ranging from 3.3 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. The ADuM3300/ADuM3301 isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions. In comparison to ADuM1300/ADuM1301 isolators, ADuM3300/ ADuM3301 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 ADuM1300/ADuM1301 or ADuM3300/ADuM3301 products is strongly determined by the design and layout of the user’s system.

Output supply current values are specified with no output load present. The supply current associated with an individual channel operating at a given data rate can be calculated as described in the Power Consumption section. See Figure 6 through Figure 8 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 9 through Figure 12 for total VDD1 and VDD2 supply currents as a function of data rate for ADuM3300/ADuM3301 channel configurations. 2 The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed. 3 The maximum data rate is the fastest data rate at which the specified pulse width distortion is guaranteed. 4 tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay is measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal. 5 tPSK is the magnitude of the worst-case difference in tPHL or tPLH that is measured between units at the same operating temperature, supply voltages, and output load within the recommended operating conditions. 6 Codirectional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of the isolation barrier. Opposing-directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on opposing sides of the isolation barrier. 7 CMH is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD2. CML is the maximum common-mode voltage slew rate that can be sustained while maintaining VO < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The transient magnitude is the range over which the common mode is slewed. 8 Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 6 through Figure 8 for information on per-channel supply current for unloaded and loaded conditions.

Output supply current values are specified with no output load present. The supply current associated with an individual channel operating at a given data rate can be calculated as described in the Power Consumption section. See Figure 6 through Figure 8 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 9 through Figure 12 for total VDD1 and VDD2 supply currents as a function of data rate for ADuM3300/ADuM3301 channel configurations. 2 The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed. 3 The maximum data rate is the fastest data rate at which the specified pulse width distortion is guaranteed. 4 tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay is measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal. 5 tPSK is the magnitude of the worst-case difference in tPHL or tPLH that is measured between units at the same operating temperature, supply voltages, and output load within the recommended operating conditions. 6 Codirectional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of the isolation barrier. Opposing-directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on opposing sides of the isolation barrier. 7 CMH is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD2. CML is the maximum common-mode voltage slew rate that can be sustained while maintaining VO < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The transient magnitude is the range over which the common mode is slewed. 8 Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 6 through Figure 8 for information on per-channel supply current for unloaded and loaded conditions.

Power supply bypassing is strongly recommended at the input and output supply pins (see Figure 14). Bypass capacitors are most conveniently connected between Pin 1 and Pin 2 for VDD1 and between Pin 15 and Pin 16 for VDD2. 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. Bypassing between Pin 1 and Pin 8 and between Pin 9 and Pin 16 should be considered unless the ground pair on each package side is connected close to the package. VDD2 GND2 VOA VOB VOC/IC NC VE2 GND2 PROPAGATION DELAY-RELATED PARAMETERS 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. INPUT (VIX) 50% tPLH OUTPUT (VOX) tPHL 50% Figure 15. 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. 05984-015 VDD1 GND1 VIA VIB VIC/OC NC VE1 GND1 While the ADuM3300/ADuM3301 improve system-level ESD reliability, they are no substitute for a robust system-level design. See Application Note AN-793 ESD/Latch-Up Considerations with iCoupler Isolation Products for detailed recommendations on board layout and system-level design. 05984-016 PC BOARD LAYOUT Figure 14. Recommended Printed Circuit Board Layout In applications involving high common-mode transients, care should be taken to ensure that board coupling across the isolation barrier is minimized. Furthermore, the board layout should be designed such that any coupling that does occur equally affects all pins on a given component side. Failure to ensure this could cause voltage differentials between pins exceeding the device’s absolute maximum ratings, thereby leading to latch-up or permanent damage. 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 ADuM3300/ADuM3301 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. Channel-to-channel matching refers to the maximum amount the propagation delay differs between channels within a single ADuM3300/ADuM3301 component. Propagation delay skew refers to the maximum amount the propagation delay differs between multiple ADuM3300/ ADuM3301 components operating under the same conditions. DC CORRECTNESS AND MAGNETIC FIELD IMMUNITY 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 ~1 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 of 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 11) by the watchdog timer circuit. The limitation on the ADuM3300/ADuM3301 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 ADuM3300/ADuM3301 are examined because it represents the most susceptible mode of operation. Rev. E | Page 17 of 20 ADuM3300/ADuM3301 Data Sheet where: β is magnetic flux density (gauss). rn is the radius of the nth turn in the receiving coil (cm). N is the number of turns in the receiving coil. Given the geometry of the receiving coil in the ADuM330x 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 16. MAXIMUM ALLOWABLE MAGNETIC FLUX DENSITY (kgauss) 10 DISTANCE = 100mm 1 DISTANCE = 5mm 0.1 0.01 1k 10k 100k 1M 10M 100M MAGNETIC FIELD FREQUENCY (Hz) Figure 17. Maximum Allowable Current for Various Current-to-ADuM3300/ADuM3301 Spacings 100 Note that at combinations of strong magnetic field and high frequency, any loops formed by printed circuit board traces could induce error voltages sufficiently large enough to trigger the thresholds of succeeding circuitry. Care should be taken in the layout of such traces to avoid this possibility. 10 1 POWER CONSUMPTION 0.1 The supply current at a given channel of the ADuM3300/ ADuM3301 isolator is a function of the supply voltage, the channel’s data rate, and the channel’s output load. 10k 100k 1M 10M MAGNETIC FIELD FREQUENCY (Hz) 100M 05984-017 0.01 0.001 1k DISTANCE = 1m 100 05984-018 V = (−dβ/dt) ∑π rn2; n = 1, 2, … , N 1000 MAXIMUM ALLOWABLE CURRENT (kA) 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, thus establishing a 0.5 V margin in which induced voltages can be tolerated. The voltage induced across the receiving coil is given by For each input channel, the supply current is given by Figure 16. 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 was of 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. The preceding magnetic flux density values correspond to specific current magnitudes at given distances from the ADuM3300/ADuM3301 transformers. Figure 17 expresses these allowable current magnitudes as a function of frequency for selected distances. The ADuM3300/ADuM3301 are extremely immune and can be affected only by extremely large currents operated at high frequency very close to the component (see Figure 17). For the 1 MHz example noted, a 0.5 kA current would have to be placed 5 mm away from the ADuM3300/ ADuM3301 to affect the component’s operation. IDDI = IDDI (Q) f ≤ 0.5 fr IDDI = IDDI (D) × (2f − fr) + IDDI (Q) f > 0.5 fr For each output channel, the supply current is given by IDDO = IDDO (Q) f ≤ 0.5 fr IDDO = (IDDO (D) + (0.5 × 10 ) × CL × VDDO) × (2f − fr) + IDDO (Q) f > 0.5 fr −3 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); it is half of the input data rate expressed in units of Mbps. 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 VDD1 and VDD2 are calculated and totaled. Figure 6 provides perchannel input supply current as a function of data rate. Figure 7 and Figure 8 provide per-channel output supply current as a function of data rate for an unloaded output condition and for a 15 pF output condition, respectively. Figure 9 through Figure 12 provide total VDD1 and VDD2 supply current as a function of data rate for ADuM3300/ADuM3301 channel configurations. Rev.

In many cases, the approved working voltage is higher than 50-year service life voltage. Operation at these high working voltages can lead to shortened insulation life. Note that the voltage presented in Figure 19 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 ADuM3300/ADuM3301 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 18, Figure 19, and Figure 20 illustrate these different isolation voltage waveforms. Bipolar ac voltage is the most stringent environment. The goal of a 50-year operating lifetime under the ac bipolar condition determines the Analog Devices recommended maximum working voltage. RATED PEAK VOLTAGE 05984-020 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. 0V Figure 18. Bipolar AC Waveform RATED PEAK VOLTAGE 05984-021 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 executes an extensive set of evaluations to determine the lifetime of the insulation structure within the ADuM3300/ ADuM3301. 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 10 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 19 or Figure 20 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 10. 0V Figure 19.
