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. These devices are ideal for driving Silicon Carbide (SiC) FETs, power MOSFETs, and IGBTs in various inverter and motor control applications. Leveraging Skyworks' proprietary silicon isolation technology, they provide up to 5.0 kVrms withstand voltage per UL1577, ensuring superior performance, temperature stability, part-to-part consistency, and common-mode rejection. The integrated DC-DC controller simplifies the implementation of an isolated supply for the driver side, with configurations available for different system voltage rails and power requirements. Options include user-adjustable frequency for emission control, soft-start for safety, and shutdown capability. The devices require minimal passive components and a miniature transformer. Key features include DESAT detection, FAULT feedback, UVLO, soft shutdown, ultra-fast short circuit protection, high CMTI, integrated Miller clamp, and automotive-grade options (AEC-Q100 qualified).
