High current gate driver SKYWORKS SI8284DC-AS for silicon carbide fet and igbt inverter applications
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 various 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 family also integrates a DC-DC controller for simplified isolated power supply implementation for the driver side. The Si828x family offers user-adjustable frequency for minimizing emissions, a soft-start function for safety, and shut-down capability. Minimal passive components and a miniature transformer are required. The input is a complementary digital input, and the isolation side features control and feedback digital signals. The controller receives information about the driver side power and fault states and can recover from faults via an active-low reset pin. The output side provides separate pull-up and pull-down pins for the gate. A dedicated DSAT pin detects desaturation and initiates a controlled shutdown using soft shutdown. An integrated Miller clamp ensures strong turn-off of the power switch.
