High current isolated gate driver SKYWORKS SI8284BD ASR for silicon carbide fet and power mosfet control
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 a wide variety of inverter and motor control applications. Utilizing Skyworks' proprietary silicon isolation technology, they support up to 5.0 kVrms withstand voltage per UL1577, offering superior performance, reduced variation with temperature and age, tighter part-to-part matching, and enhanced common-mode rejection. The Si828x family also integrates a DC-DC controller for simplified isolated power supply implementation for the driver side. The DC-DC controller is available in two configurations: Si8281/83 with integrated power switches (limited DC-DC voltage input to device bias) and Si8282/84 with external power switches (accepting higher voltage input power). 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, and the isolation side offers control and feedback digital signals. The driver side provides separate pull-up and pull-down pins, a dedicated DSAT pin for desaturation detection with controlled soft shutdown, and an integrated Miller clamp for strong power switch turn-off.
