![]() ![]() Si8286 devices are packaged in a configuration common to many optocoupler based IGBT drivers. This provides a simple method for providing the isolated power rail necessary for the isolated driver and significantly simplifies layout. Orderable options in the Si8281BD-IS family include an integrated, isolated dc-dc controller. A Miller clamp is also integrated in to facilitate a strong turn-off of the power switch. A dedicated DSAT pin detects the desaturation condition and immediately shuts down the driver in a controlled manner. the evaluation board can be used to test either one of the top and bottom half bridge. ![]() On the output side, the Si8281BD-IS provides separate pull-up and pull-down pins for the gate. Isolated IGBT or SiC/GaN MOSFET Gate Driver Evaluation Board. Si8281BD-IS devices support up to to 5 kVRMS withstand voltage per 9, provide feedback to the controller about the driver side power state and fault state and recover the device from fault through an active-low reset pin. The board includes 2W power supplies with undervoltage protection and reverse polarity protection. This board can be used in conjunction with Wolfspeed CIL boards or Evaluation kits. ![]() Si8281BD-IS are isolated, high current gate drivers with integrated system safety and feedback functions, ideal for driving IGBTs used in a wide variety of inverter and motor control applications. Wolfspeed’s CGD1700HB2M-UNA is a half bridge gate driver board for evaluation of Wolfspeed C3M SiC MOSFET’s and modules. ![]()
