ADI ADuM4121 High Voltage, Isolated Gate Driver with Internal Miller Clamp, 2 A Output with Thermal Shutdown
The ADuM4121/ADuM4121-1 are 2 A isolated, single-channel drivers that employ Analog Devices, Inc.’s iCoupler® technology to provide precision isolation. The ADuM4121/ADuM4121-1 provide 5 kV rms isolation in the wide-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 ADuM4121/ADuM4121-1 operate with an input supply ranging from 2.5 V to 6.5 V, providing compatibility with lower voltage systems.
