ADuM4146 High Voltage Isolated Bipolar Gate Driver

Analog Devices Inc. ADuM4146 High Voltage Isolated Bipolar Gate Driver is optimized for driving Silicon Carbide (SiC) Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs). The ADuM4146 features iCoupler® technology, which provides isolation between the input signal and the output gate drive. The device includes a Miller clamp to provide robust SiC turn-off with a single-rail supply when the gate voltage drops to less than 2V. Operation with unipolar or bipolar secondary supplies is possible with or without the Miller clamp operation.
