The ADuM4146 high voltage isolated bipolar gate driver is optimised for driving Silicon Carbide (SiC) Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs).
The device features iCoupler technology, which provides isolation between the input signal and the output gate drive.
It 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.
Applications for the ADuM4146 isolated bipolar gate driver include SiC MOSFET and IGBT gate drivers, photovoltaic (PV) inverters, motor drives, and power supplies.
