SKYWORKS SI8283CD ASR isolated gate driver integrated DC DC converter for SiC FET and MOSFET switching
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. Utilizing 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. The Si828x family supports user-adjustable frequency for emissions control, soft-start for safety, and shutdown capabilities. Minimal passive components and a miniature transformer are required. The input accepts complementary digital signals, and the isolation side features control and feedback signals. The device monitors the driver side power and fault states, with an active-low reset pin for fault recovery. On the output, separate pull-up and pull-down pins are provided for the gate. A dedicated DSAT pin detects desaturation, initiating a controlled soft shutdown. An integrated Miller clamp ensures strong power switch turn-off. Automotive Grade options are available, built with automotive-specific manufacturing processes for high robustness and low defectivity.
