Integrated DC DC Converter and Isolated Gate Driver SKYWORKS SI8283DC-ASR for Compact Power Solutions
Si828x Family: SiC FET-Ready ISODrivers with Integrated DC-DC Converters
The Si828x family (Si8281/82/83/84) comprises 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 a wide range of inverter and motor control applications. Utilizing Skyworks' proprietary silicon isolation technology, they support up to 5.0 kVrms withstand voltage per UL1577, offering superior performance, reduced variation with temperature and age, tighter part-to-part matching, and enhanced common-mode rejection compared to other isolation technologies. The family also integrates a DC-DC controller for simplified isolated power supply implementation for the driver side. The Si828x devices feature user-adjustable frequency for minimizing emissions, a soft-start function for safety, and shut-down capability. They 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, and integrated Miller clamp. Automotive-grade versions are available, built with automotive-specific manufacturing flows and AEC-Q100 qualification.
