SKYWORKS SI8284CD AS isolated gate driver supporting up to 5 kvrms withstand voltage for motor 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 various inverter and motor control applications. Utilizing Skyworks' proprietary silicon isolation technology, they support up to 5.0 kVrms withstand voltage (UL1577), offering superior performance, temperature stability, part-to-part matching, 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. The Si828x family features user-adjustable frequency for emissions minimization, a soft-start function for safety, and shut-down capability. They require minimal passive components and a miniature transformer. Input is a complementary digital input with control and feedback signals on the isolation side. The output side provides separate pull-up and pull-down pins for the gate, a dedicated DSAT pin for desaturation detection and controlled shutdown, and an integrated Miller clamp for strong turn-off.
