The ADuM3223 provides 3000 V rms isolation in the narrow body, 16-lead SOIC package, and the ADuM4223 provides 5000 V rms isolation in the wide body, 16-lead SOIC package. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to the alternatives, such as the combination of pulse transformers and gate drivers. APPLICATIONS As a result, the ADuM3223/ADuM4223 provide reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages. The ADuM3223/ADuM4223 isolators each provide two independent isolated channels. They operate with an input supply ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems. In comparison to gate drivers employing high voltage level translation methodologies, the ADuM3223/ADuM4223 offer the benefit of true, galvanic isolation between the input and each output. Each output may be continuously operated up to 560 VPEAK relative to the input, thereby supporting low-side switching to negative voltages. The differential voltage between the high-side and low-side may be as high as 700 VPEAK.

Power supply bypassing is required at the input and output supply pins, as shown in Figure 19. Use a small ceramic capacitor with a value between 0.01 μF and 0.1 μF to provide a good high frequency bypass. On the output power supply pin, VDDA or VDDB, it is recommended to also add a 10 μF capacitor to provide the charge required to drive the gate capacitance at the ADuM3223/ ADuM4223 outputs. On the output supply pin, the bypass capacitor use of vias should be avoided or multiple vias should be employed to reduce the inductance in the bypassing. The total lead length between both ends of the smaller capacitor and the input or output power supply pin should not exceed 5 mm.

Recommended PCB Layout 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 output. The ADuM3223/ADuM4223 specify tDLH (see Figure 20) as the time between the rising input high logic threshold, VIH, to the output rising 10% threshold. Likewise, the falling propagation delay, tDHL, is defined as the time between the input falling logic low threshold, VIL, and the output falling 90% threshold. The rise and fall times are dependent on the loading conditions and are not included in the propagation delay, which is the industry standard for gate drivers. 90% OUTPUT 10% VIH INPUT VIL tR tF Figure 20. Propagation Delay Parameters 10450-005 tDHL tDLH THERMAL LIMITATIONS AND SWITCH LOAD CHARACTERISTICS For isolated gate drivers, the necessary separation between the input and output circuits prevents the use of a single thermal pad beneath the part, and heat is, therefore, dissipated mainly through the package pins. Package thermal dissipation limits the performance of switching frequency vs. output load, as illustrated in Figure 7 and Figure 8 for the maximum load capacitance that can be driven with a 1 Ω series gate resistance for different values of output voltage. For example, this curve shows that a typical ADuM3223 can drive a large MOSFET with 140 nC gate charge at 8 V output (which is equivalent to a 17 nF load) up to a frequency of about 300 kHz. OUTPUT LOAD CHARACTERISTICS 10450-119 NC Propagation delay skew refers to the maximum amount that the propagation delay differs between multiple ADuM3223/ ADuM4223 components operating under the same conditions. The ADuM3223/ADuM4223 output signals depend on the characteristics of the output load, which is typically an N-channel MOSFET. The driver output response to an N-channel MOSFET load can be modeled with a switch output resistance (RSW), an inductance due to the printed circuit board trace (LTRACE), a series gate resistor (RGATE), and a gate-to-source capacitance (Cgs), as shown in Figure 21. VIA ADuM3223/ ADuM4223 VOA RSW RGATE LTRACE VO CGS 10450-006 VIA Channel-to-channel matching refers to the maximum amount that the propagation delay differs between channels within a single ADuM3223/ADuM4223 component. Figure 21. RLC Model of the Gate of an N-Channel MOSFET RSW is the switch resistance of the internal ADuM3223/ ADuM4223 driver output, which is about 1.1 Ω. RGATE is the intrinsic gate resistance of the MOSFET and any external series resistance. A MOSFET that requires a 4 A gate driver has a typical intrinsic gate resistance of about 1 Ω and a gate-tosource capacitance, CGS, of between 2 nF and 10 nF. LTRACE is the inductance of the printed circuit board trace, typically a value of 5 nH or less for a well-designed layout with a very short and wide connection from the ADuM3223/ADuM4223 output to the gate of the MOSFET. The following equation defines the Q factor of the RLC circuit, which indicates how the ADuM3223/ADuM4223 output responds to a step change. For a well-damped output, Q is less than 1. Adding a series gate resistance dampens the output response. Rev. 0| Page 15 of 20 ADuM3223/ADuM4223 Output ringing can be reduced by adding a series gate resistance to dampen the response. For applications of less than 1 nF load, it is recommended to add a series gate resistor of about 2 Ω to 5 Ω. The ADuM3223/ADuM4223 is immune to external magnetic fields. The limitation on the ADuM3223/ADuM4223 magnetic field immunity is set by the condition in which induced voltage in the transformer 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 ADuM3223/ADuM4223 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, therefore establishing a 0.5 V margin in which induced voltages can be tolerated. The voltage induced across the receiving coil is given by V = (−dβ/dt) ∑π rn2, n = 1, 2, ... , N 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). 0.1 0.001 1k 10k 100k 1M 10M 100M MAGNETIC FIELD FREQUENCY (Hz) Figure 22. Maximum Allowable External Magnetic Flux Density For example, at a magnetic field frequency of 1 MHz, the maximum allowable magnetic field of 0.08 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), the received pulse is reduced 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 away from the ADuM3223/ADuM4223 transformers. Figure 23 expresses these allowable current magnitudes as a function of frequency for selected distances. As shown, the ADuM3223/ADuM4223 are immune and only can be affected by extremely large currents operated at a high frequency and very close to the component. For the 1 MHz example, a 0.2 kA current must be placed 5 mm away from the ADuM3223/ADuM4223 to affect the component’s operation. 1k MAXIMUM ALLOWABLE CURRENT (kA) If the decoder receives no internal pulses for more than about 3 µs, the input side is assumed to be unpowered or nonfunctional, in which case, the isolator output is forced to a default low state by the watchdog timer circuit. In addition, the outputs are in a low default state while the power is coming up before the UVLO threshold is crossed. 1 0.01 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 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. 10 10450-122 In Figure 5, the ADuM3223/ADuM4223 output waveforms for a 12 V output are shown for a CGS of 2 nF. Note the small amount of ringing of the output in Figure 5 with CGS of 2 nF, RSW of 1.1 Ω, RGATE of 0 Ω, and a calculated Q factor of 0.75, where less than 1 is desired for good damping. Given the geometry of the receiving coil in the ADuM3223/ ADuM4223 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 22.

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. 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 IDDO = (IDDO(D) + (0.5) × 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 supply current, the supply currents for each input and output channel corresponding to IDD1, IDDA, and IDDB are calculated and totaled. Figure 9 provides total input IDD1 supply current as a function of data rate for both input channels. Figure 10 provides total IDDA or IDDB supply current as a function of data rate for both outputs loaded with 2 nF capacitance. A bipolar ac voltage environment is the worst case for the iCoupler products and is the 50-year operating lifetime that Analog Devices recommends for 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. Any crossinsulation voltage waveform that does not conform to Figure 25 or Figure 26 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 12. Note that the voltage presented in Figure 25 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 0V Figure 24. Bipolar AC Waveform INSULATION LIFETIME 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. 0| Page 17 of 20 RATED PEAK VOLTAGE 10450-010 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 ADuM3223/ ADuM4223. 0V Figure 25. Unipolar AC Waveform RATED PEAK VOLTAGE 10450-011 IDDO = IDDO(Q) The insulation lifetime of the ADuM3223/ADuM4223 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 24, Figure 25, and Figure 26 illustrate these different isolation voltage waveforms. 10450-009 The supply current at a given channel of the ADuM3223/ ADuM4223 isolator is a function of the supply voltage, channel data rate, and channel output load. 0V Figure 26.
