SKYWORKS SI8284CC AS integrated DC DC converter gate driver for Silicon Carbide FET and power MOSFET
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. Utilizing Skyworks' proprietary silicon isolation technology, they achieve up to 5.0 kVrms withstand voltage (UL1577), providing superior performance, temperature stability, part-to-part matching, and common-mode rejection. The integrated DC-DC controller simplifies isolated supply implementation for the driver side, with configurations available for different system voltage rails and power needs. The Si8281/83 feature integrated power switches with limited DC-DC voltage input, while the Si8282/84 use external switches for higher voltage input capabilities. Options for user-adjustable frequency, soft-start, and shutdown are available. These devices require minimal passive components and a miniature transformer. Input is a complementary digital input, with control and feedback signals on the isolation side. The driver outputs provide separate pull-up and pull-down pins, a DSAT pin for desaturation detection and controlled shutdown, and an integrated Miller clamp for strong turn-off.
