Key performance specifications of the ADuM4221 include excellent noise immunity (CMTI of 150/µs), a critical metric in fast-switching/high EMI environments, and improved thermal performance through low Rdson, both of which allow a customer to take full advantage of the output power and efficiency that SiC and GaN technologies have to offer.

The ADuM4221 is a 4 A isolated, half bridge gate driver that employs the Analog Devices, Inc., iCoupler® technology to provide independent and isolated high-side and low-side outputs. The ADuM4221 provides 5700 V rms isolation in the increased creepage wide body, 16-lead SOIC_IC 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.
