Increased creepage wide body, 16-lead SOIC_IC
The ADuM4221/ADuM4221-1/ADuM4221-2 are 4 A isolated, half bridge gate drivers that employ the Analog Devices, Inc., iCoupler® technology to provide independent and isolated high-side and low-side outputs. The ADuM4221/ADuM4221-1/ADuM4221-2 provide 5700 V rms isolation in an increased creepage wide body, 16-lead SOIC_IC. 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 isolators operate with a logic input voltage ranging from 2.5 V to 6.5 V, providing compatibility with lower voltage systems. In comparison to gate drivers employing high voltage level translation methodologies,
