Si8281 Isolated Gate Driver Evaluation Kit


The SI8281 evaluation board highlights the Si8281CD-IS configuration of the Si828x family of isolated IGBT drivers. This device combines a high-quality, isolated gate driver with a high-efficiency dc-dc converter to simplify system power routing.

The board includes all BOM necessary for the dc-dc power converter and emphasizes the small space used by outlining the basic BOM in white. The board requires a 5 V input, and the power converter delivers a -9 V and a 15 V rail on the driver side. The converter can deliver up to 2 W of power. Sockets are provided to allow the user to mount an IGBT or representative capacitor directly to the board. Alternately, the board can be wired to an in situ switch through the output screw terminals. Power is applied through screw terminals, and signals can be applied or monitored through a standard header.
