Si8286 Datasheet | Skyworks Solutions

Features The Si828x (Si8285 and Si8286) are isolated, high current gate drivers with integrated system safety and feedback functions. The devices are ideal for driving Silicon Carbide (Si C) FETs, power MOSFETs, and IGBTs used in a wide variety of inverter and motor control applications. The Si8285 and Si8286 isolated gate drivers utilize Skyworks' proprietary silicon isolation technology, supporting up to 5.0 k Vrms withstand voltage per UL1577. This technology enables higher performance, reduced variation with temperature and age, tighter part-to-part matching, and superior mon-mode rejection pared to other isolated gate driver technologies. The input to the device is a plementary digital input that can be utilized in several configurations. The input side of the isolation also has several control and feedback digital signals. The controller to the device receives information about the driver side power state (Si8285) and fault state of the device and recovers the device from fault through an active-low reset pin. On the output side, the Si8285 provides separate pull-up and pull-down pins for the gate. The Si8286 has a single pin for both functions. A dedicated DSAT pin detects a desaturation condition and immediately shuts down the driver in a controlled manner using soft shutdown. The Si8285 device also integrates a Miller clamp to assure a strong turn-off of the power switch. Automotive Grade is available. These products are built using automotive-specific flows at all steps in the manufacturing process to ensure the robustness and low defectivity required for automotive applications.
