Product Details
The ADuM3123 is a 4.0 A isolated, single channel driver that employs Analog Devices, Inc.’s iCoupler® technology to provide precision isolation. The ADuM3123 provides 3000 VRMS 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 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 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.
Applications
- Switching power supplies
- Isolated IGBT/MOSFET gate drives
- Industrial inverters
