Isolated gate driver SKYWORKS SI8282DD-AS featuring user adjustable frequency for emission reduction
Product Description
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 inverter and motor control applications. Utilizing Skyworks' proprietary silicon isolation technology, they 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 family also integrates a DC-DC controller for simplified isolated supply implementation. The Si8281 and Si8283 feature integrated power switches with limited DC-DC voltage input, while the Si8282 and Si8284 utilize external power switches for higher voltage input capability. Available options include user-adjustable frequency for emission minimization, soft-start for safety, and shutdown capability. The 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 side 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 power switch turn-off.
