ADuM1412 GENERAL DESCRIPTION The ADuM1410/ADuM1411/ADuM14121 are four-channel digital isolators based on Analog Devices, Inc., iCoupler(R) technology. Combining high speed CMOS and monolithic air core transformer technologies, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices. By avoiding the use of LEDs and photodiodes, iCoupler devices remove the design difficulties commonly associated with optocouplers. The usual concerns that arise with optocouplers, such as 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 1 devices consume one-tenth to one-sixth the power of optocouplers at comparable signal data rates. The ADuM1410/ADuM1411/ADuM1412 isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide) up to 10 Mbps. All models operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. All products also have a default output control pin. This allows the user to define the logic state the outputs are to adopt in the absence of the input power. Unlike other optocoupler alternatives, the ADuM1410/ADuM1411/ ADuM1412 isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down 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 8 through Figure 10 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 11 through Figure 15 for total VDD1 and VDD2 supply currents as a function of data rate for ADuM1410/ADuM1411/ADuM1412 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 Input enable time is the duration from when VDISABLE is set low until the output states are guaranteed to match the input states in the absence of any input data logic transitions. If an input data logic transition within a given channel does occur within this time interval, the output of that channel reaches the correct state within the much shorter duration as determined by the propagation delay specifications within this data sheet. Input disable time is the duration from when VDISABLE is set high until the output states are guaranteed to reach their programmed output levels, as determined by the CTRL2 logic state (see Table 14). 9 Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 8 through Figure 10 for information on per-channel supply current for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating the per-channel supply current for a given data rate. 1 Rev.

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 8 through Figure 10 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 11 through Figure 15 for total VDD1 and VDD2 supply currents as a function of data rate for ADuM1410/ADuM1411/ADuM1412 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 Input enable time is the duration from when VDISABLE is set low until the output states are guaranteed to match the input states in the absence of any input data logic transitions. If an input data logic transition within a given channel does occur within this time interval, the output of that channel reaches the correct state within the much shorter duration as determined by the propagation delay specifications within this data sheet. Input disable time is the duration from when VDISABLE is set high until the output states are guaranteed to reach their programmed output levels, as determined by the CTRL2 logic state (see Table 14). 9 Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 8 through Figure 10 for information on per-channel supply current for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating the per-channel supply current for a given data rate. 1 Rev.

M | Page 18 of 22 Data Sheet ADuM1410/ADuM1411/ADuM1412 APPLICATIONS INFORMATION DC CORRECTNESS AND MAGNETIC FIELD IMMUNITY The ADuM1410/ADuM1411/ADuM1412 digital isolators require no external interface circuitry for the logic interfaces. Power supply bypassing is strongly recommended at the input and output supply pins (see Figure 16). 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 F and 0.1 F. 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 also be considered unless both ground pins on each package are connected together close to the package. Positive and negative logic transitions at the isolator input cause narrow (~1 ns) pulses to be sent to the decoder using 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 s, 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 approximately 5 s, the input side is assumed to be unpowered or nonfunctional, in which case the isolator output is forced to a default state (see Table 14) by the watchdog timer circuit.

Recommended Printed Circuit Board Layout In applications involving high common-mode transients, it is important to minimize board coupling across the isolation barrier. Furthermore, users should design the board layout so 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. See the AN-1109 Application Note for board layout guidelines. PROPAGATION DELAY-RELATED PARAMETERS Propagation delay is a parameter that describes the time it takes a logic signal to propagate through a component. The input-tooutput propagation delay time for a high-to-low transition may differ from the propagation delay time of a low-to-high transition. INPUT (VIx) 50% The magnetic field immunity of the ADuM1410/ADuM1411/ ADuM1412 is determined by the changing magnetic field, which induces a voltage in the transformer's receiving coil large enough 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 ADuM1410/ADuM1411/ADuM1412 is examined because it represents the most susceptible mode of operation. 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 V = (-d/dt) rn2; n = 1, 2, ... , N where: 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 ADuM1410/ ADuM1411/ADuM1412 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 at a given frequency can be calculated. The result is shown in Figure 18. 50% Figure 17. Propagation Delay Parameters Pulse width distortion is the maximum difference between these two propagation delay values and an indication of how accurately the timing of the input signal is preserved. Channel-to-channel matching refers to the maximum amount the propagation delay differs between channels within a single ADuM1410/ADuM1411/ADuM1412 component. Propagation delay skew refers to the maximum amount the propagation delay differs between multiple ADuM1410/ ADuM1411/ADuM1412 components operating under the same conditions. Rev.

This is about 50% of the sensing threshold and does not cause a faulty output transition. Similarly, if such an event occurred 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. The preceding magnetic flux density values correspond to specific current magnitudes at given distances from the ADuM1410/ADuM1411/ADuM1412 transformers. Figure 19 shows these allowable current magnitudes as a function of frequency for selected distances. As shown, the ADuM1410/ ADuM1411/ADuM1412 is extremely immune and can be affected only by extremely large currents operated at high frequency very close to the component. For the 1 MHz example noted previously, a 0.5 kA current would have to be placed 5 mm away from the ADuM1410/ADuM1411/ADuM1412 to affect the operation of the component.

Maximum Allowable Current for Various Current-to-ADuM1410/ADuM1411/ADuM1412 Spacings Note that at combinations of strong magnetic field and high frequency, any loops formed by printed circuit board traces can 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. POWER CONSUMPTION The supply current at a given channel of the ADuM1410/ ADuM1411/ADuM1412 isolators is a function of the supply voltage, the data rate of the channel, and the output load of the channel. For each input channel, the supply current is given by IDDI = IDDI (Q) f 0.5 fr IDDI = IDDI (D) x (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 x 10 ) x CL x VDDO) x (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 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 VDD1 and VDD2 supply current, the supply currents for each input and output channel corresponding to VDD1 and VDD2 are calculated and totaled. Figure 8 and Figure 9 show per-channel supply currents as a function of data rate for an unloaded output condition. Figure 10 shows the per-channel supply current as a function of data rate for a 15 pF output condition. Figure 11 through Figure 15 show the total VDD1 and VDD2 supply current as a function of data rate for ADuM1410/ ADuM1411/ADuM1412 channel configurations. INSULATION LIFETIME 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 ADuM1410/ ADuM1411/ADuM1412. Rev. M | Page 20 of 22 Data Sheet ADuM1410/ADuM1411/ADuM1412 Note that the voltage presented in Figure 21 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. RATED PEAK VOLTAGE 06580-020 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. The values shown in Table 10 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 50-year service life voltage. Operation at these high working voltages can lead to shortened insulation life in some cases. 0V Figure 20. Bipolar AC Waveform RATED PEAK VOLTAGE 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 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 the voltage conforms to either the unipolar ac or dc voltage case. Any cross-insulation voltage waveform that does not conform to Figure 21 or Figure 22 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. Rev. M | Page 21 of 22 06580-021 The insulation lifetime of the ADuM1410/ADuM1411/ ADuM1412 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 20, Figure 21, and Figure 22 illustrate these different isolation voltage waveforms. 0V 06580-022 Figure 21. Unipolar AC Waveform 0V Figure 22.
