ADUM4121-1ARIZ

ADUM4121-1 is a single-channel driver that employ Analog Devices, Inc.’s iCoupler® technology to provide precision isolation. Combining high speed CMOS and monolithic transformer technology, this isolation component provide outstanding performance characteristics superior to alternatives such as the combination of pulse transformers and gate drivers. The device operate with an input supply ranging from 2.5V to 6.5V, providing compatibility with lower voltage systems. In comparison to gate drivers that employ high voltage level translation methodologies, the device offer the benefit of true, galvanic isolation between the input and the output. It is widely used in application such as switching power supplies, isolated IGBT/MOSFET gate drives, industrial inverters, gallium nitride (GaN)/silicon carbide (SiC) power devices etc.
