Narrow body, 8-lead SOIC

The ADuM3123 is a 4.0 A isolated, single channel driver that employs Analog Devices, Inc. iCoupler^® technology to provide precision isolation. The ADuM3123 provides 3000 V_RMS isolation in the narrow body 8-lead SOIC package. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as the combination of pulse transformers and gate drivers.

The ADuM3123 operates 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 ADuM3123 offer the benefit of true, galvanic isolation between the input and the output. The output may be continuously operated up to 380 V rms relative to the input.

As a result, the ADuM3123 provide reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.

Product Details

The EVAL-ADuM3123 EBZ supports the ADuM3123 isolated precision gate driver. Because the evaluation board has footprints for isolated gate bipolar transistors (IGBTs) and MOSFETs in TO-263 or TO-252 packages, respectively, the ADuM3123 can be evaluated with many different power devices.

The ADuM3123ARZ model represents a superset of the ADuM3123 models because it has the lowest minimum output voltage (4.4 V). The ADuM3123BRZ and ADuM3123CRZ models have minimum output voltages of 7.4 V and 11.1 V, respectively.

Complete information about the ADuM3123 is available in the ADuM3123 data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
