Product Description

The Si828x family (Si8281/82/83/84) comprises isolated, high-current gate drivers with integrated system safety and feedback functions, ideal for driving Silicon Carbide (SiC) FETs, power MOSFETs, and IGBTs in inverter and motor control applications. Utilizing Skyworks' proprietary silicon isolation technology, these devices offer up to 5.0 kVrms withstand voltage per UL1577, providing superior performance, reduced variation with temperature and age, tighter part-to-part matching, and enhanced common-mode rejection. The integrated DC-DC controller simplifies the implementation of an isolated supply for the driver side. The Si828x family offers two DC-DC controller configurations: Si8281/83 with integrated power switches (limited DC-DC voltage input) and Si8282/84 with external power switches (higher voltage input capability). Features include user-adjustable frequency, soft-start, and shut-down capability, requiring minimal passive components and a miniature transformer. The input is a complementary digital input, with control and feedback signals on the isolation side. The output provides separate pull-up and pull-down pins, a dedicated DSAT pin for desaturation detection and controlled shutdown, and an integrated Miller clamp for strong turn-off.
