Si8285/86 Data Sheet SiC FET-Ready ISODrivers with System Safety Features KEY FEATURES The Si828x (Si8285 and Si8286) are isolated, high current gate drivers with integrated sys- tem safety and feedback functions. The devices are ideal for driving Silicon Carbide (SiC) System Safety Features FETs, power MOSFETs, and IGBTs used in a wide variety of inverter and motor control DESAT detection applications. The Si8285 and Si8286 isolated gate drivers utilize Silicon Labs proprietary FAULT feedback silicon isolation technology, supporting up to 5.0 kVrms withstand voltage per UL1577. This Undervoltage Lock Out (UVLO) technology enables higher performance, reduced variation with temperature and age, tighter including 13 and 15 V for SiC part-to-part matching, and superior common-mode rejection compared to other isolated gate FET driver technologies. Soft shutdown on fault condition Ultra-fast short circuit protection The input to the device is a complementary digital input that can be utilized in several configu- << 1 s rations. The input side of the isolation also has several control and feedback digital signals. Robust reference design The controller to the device receives information about the driver side power state (Si8285) for current boost, DESAT and fault state of the device and recovers the device from fault through an active-low reset pin. adjustment, soft shutdown tuning, and external Miller clamp On the output side, the Si8285 provides separate pull-up and pull-down pins for the gate. transistor The Si8286 has a single pin for both functions. A dedicated DSAT pin detects a desaturation High-performance isolation condition and immediately shuts down the driver in a controlled manner using soft shutdown. technology The Si8285 device also integrates a Miller clamp to assure a strong turn-off of the power High CMTI 125 kV/s switch. 30 V driver-side supply voltage Automotive Grade is available. These products are built using automotive-specific flows at all Integrated Miller clamp (Si8285 steps in the manufacturing process to ensure the robustness and low defectivity required for only) automotive applications.
