High Voltage Isolated Gate Driver SKYWORKS SI8282CD-AS with Silicon Isolation and External Power Switch Support
Si828x Family: SiC FET-Ready ISODrivers with Integrated DC-DC Converters
The Si828x family (Si8281/82/83/84) comprises isolated, high-current gate drivers featuring 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 achieve up to 5.0 kVrms withstand voltage (UL1577), offering superior performance, temperature stability, part-to-part consistency, and common-mode rejection compared to other isolation technologies. 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. The Si8281 and Si8283 include integrated power switches with limited DC-DC voltage input, while the Si8282 and Si8284 utilize external power switches for higher input voltage capability. User-adjustable frequency for emission control, soft-start, and shutdown are optional features. These devices require minimal passive components and a miniature transformer. The input accepts complementary digital signals, and the isolation boundary provides control and feedback signals. The driver side offers separate pull-up and pull-down pins, a dedicated DSAT pin for desaturation detection and controlled shutdown, and an integrated Miller clamp for strong power switch turn-off. Automotive Grade versions are available, built with automotive-specific manufacturing flows and AEC-Q100 qualification.
