The ADuM3223/ADuM4223 are 4 A isolated, half-bridge gatedrivers that employ the Analog Devices, Inc., iCoupler® technology to provide independent and isolated high-side and low-sideoutputs. The ADuM3223 provides 3000 V rms isolation in thenarrow 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. The ADuM3223/ADuM4223 isolators each provide two independent isolated channels. They operate with an inputsupply ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems. In comparison to gate drivers employinghigh 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 537 V peak relative to the input, thereby supporting low-side switching to negative voltages. The differential voltagebetween the high-side and low-side may be as high as 800 V peak.As a result, the ADuM3223/ADuM4223 provide reliable controlover the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.Applications Switching power supplies Isolated IGBT/MOSFET gate drives Industrial inverters Automotive

The ADuM3480 / ADuM3481 / ADuM3482 are quad-channel digital isolators based on the Analog Devices, Inc.,iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. With typical propagation delay reduced to 25 ns, pulse width distortion is also halved.The four channels of the ADuM3480 / ADuM3481 / ADuM3482 are available in a variety of channel configurations with two data rate grades up to 25 Mbps (see the Ordering Guide section). All models use separate core and I/O power supplies. The core operates between 3.0 V and 5.5 V, whereas the I/O supply can range from 1.8 V to 5.5 V. If operation is required within the range of the core supply, the two supplies can be tied together to allow single-supply operation. When the I/O must interface with logic levels that are different from the core supply voltage, then the I/O supply can be operated independently of the core supply over a wider range. The minimum I/O supply voltage is 1.8 V, allowing compatibility with low voltage logic. Both core and I/O supplies are required for proper operation.APPLICATIONS General-purpose multichannel isolation SPI interface/data converter isolation Industrial field bus isolation

The ADuM4470 / ADuM4471 / ADuM4472 / ADuM4473 / ADuM4474 are quad-channel, digital isolations with a regulated DC/DC isolated power supply controller with an internal MOSFET driver. The DC/DC controller has an internal isolated PWM feedback from the secondary side based on the iCoupler® chip scale transformer technology and complete loop compensation. This eliminates the need to use an optocoupler for feedback and compensates the loop for stability.The ADuM447x isolator provides a more stable output voltage and higher efficiency compared to unregulated isolated DC/DC jpower supplies. The fully integrated feedback and loop compensation in a wide-body SOIC package provide a smaller form factor and 8.3 mm creepage distance solution. The regulated feedback provides a relatively flat efficiency curve over the full output power range.

The ADuM7640 / ADuM7641 / ADuM7642 / ADuM7643 are 6-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. These 1 kV digital isolation devices are packaged in a small 20-lead QSOP.
