Si8282BD-IS

Si8282BD-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. Si8282BD-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. On the output side, the Si8282BD-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 Si8282BD-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.
