Si8284ED-IS

Si8284ED-IS


Si8284ED-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. Si8284ED-IS  devices support up to to 5 kVRMS withstand voltage per 15, 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. On the output side, the Si8284ED-IS provides separate pull-up and pull-down pins for the gate. A dedicated DSAT pin detects the desaturation condition and immediately shuts down the driver in a controlled manner. A Miller clamp is also integrated in to facilitate a strong turn-off of the power switch. Orderable options in the Si8284ED-IS family include an integrated, isolated dc-dc controller. This provides a simple method for providing the isolated power rail necessary for the isolated driver and significantly simplifies layout. Si8286 devices are packaged in a configuration common to many optocoupler based IGBT drivers.

Si8284 Isolated Gate Driver Evaluation Kit

The Si8284V2-KIT’s evaluation board highlights the Si8284 part number from the Si828x family of isolated SiC FET and IGBT gate drivers. The Si8284 combines a high-quality, isolated gate driver with a high-efficiency dc-dc converter to simplify system power routing. The dc-dc converter in this configuration utilizes an external FET for power switching, which allows up to 24V input voltage.
