Features

• ADuM3220/ADuM3221, 2.5kVrms Isolated 4A Dual Channel Gate Driver, Analog Devices. The ADuM3220 and ADuM3221 from Analog Devices are 4A dual channel gate drivers incorporating Analog Devices ‘ iCoupler® technology. The combination of high speed CMOS and monolithic transformer technology provide superior performance when compared to alternatives such as the combination of pulse transformers and gate drivers. Digital isolation is provided in 2 independent isolation channels. Features. 4A peak output current 60ns maximum isolator and driver propagation delay 5ns maximum channel-to-channel matching 3.3V to 5V input logic 4.5V to 18V output drive Thermal shutdown protection at >150°C Default low output High frequency operation: DC to 1MHz CMOS input logic levels High common-mode transient immunity: >25kV/μs Enhanced system-level ESD performance per IEC 61000-4-x 2500Vrms isolation voltage. Typical Applications. Isolated synchronous DC-to-DC converters MOSFET/IGBT gate drivers
