Integrated DC-DC converter isolated gate driver SKYWORKS SI8282EC-ASR for power MOSFET and IGBT control
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 optimized 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 (UL1577), ensuring superior performance, stability across temperature and age, tighter part-to-part matching, and enhanced 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 Si828x family features user-adjustable frequency for emissions control, a soft-start function for safety, and shutdown capability. Minimal passive components and a miniature transformer are required. The input accepts complementary digital signals, and the isolation boundary provides control and feedback digital signals for monitoring the driver side power and fault states, with an active-low reset for fault recovery. The output stage offers separate pull-up and pull-down pins, a dedicated DSAT pin for desaturation detection and controlled shutdown, and an integrated Miller clamp for robust turn-off. Automotive Grade options are available, built with automotive-specific manufacturing flows for enhanced robustness and low defectivity.
