Si828x Family: SiC FET-Ready ISODrivers with Integrated DC-DC Converters

The Si828x family (Si8281/82/83/84) offers isolated, high-current gate drivers with integrated system safety and feedback functions, ideal for driving Silicon Carbide (SiC) FETs, power MOSFETs, and IGBTs in inverter and motor control applications. Leveraging Skyworks' proprietary silicon isolation technology, these devices achieve up to 5.0 kVrms withstand voltage (UL1577), providing superior performance, temperature stability, part-to-part matching, and common-mode rejection compared to other isolation technologies. The integrated DC-DC controller simplifies the implementation of an isolated supply for the driver side. The Si8281/83 feature integrated power switches with limited DC-DC voltage input, while the Si8282/84 utilize an external power switch for higher voltage input capability. Options include user-adjustable frequency for emission control, soft-start for safety, and shutdown capability. Minimal passive components and a miniature transformer are required. The input is a complementary digital input, with control and feedback signals on the isolation side. The driver output provides separate pull-up and pull-down pins, a dedicated DSAT pin for desaturation detection and controlled shutdown, and an integrated Miller clamp for strong turn-off.
