Silicon Labs and Wolfspeed Partner to Deliver High-Performance Power Module Solution

Wolfspeed power modules are used across numerous power applications, including EV chargers and motor drives in the industrial and automotive markets.

Silicon Labs introduced the new Si823Hx Gate Driver Board, an all-in-one isolation solution suited for the recently launched Wolfspeed WolfPACK power module. Featuring the Si823Hx isolated gate driver and Si88xx digital isolator with integrated dc-dc converter, the board delivers suitable performance in a compact and cost-effective design, designed for a wide range of modules. 

Silicon Labs’ isolated gate driver technology is leveraged for a variety of power applications including high-power converters and inverters, motor and traction drives, and electric vehicle (EV) chargers. The Si823Hx gate driver board delivers ideal performance to drive and protect power modules employing any switch technology, including advanced Silicon Carbide (SiC) based modules, used in demanding high-power applications.

The two-channel Si823Hx isolated gate driver delivers suitable value with built-in dead-time control and overlap protection in a small package, enabling it to drive a half-bridge topology safely and with minimal design effort. The Si88xx device not only communicates power module temperature to the controller, but also generates all the power supplies for the board.

A complete suite of design resources, developed in partnership with Wolfspeed, are available to jump-start your Wolfspeed WolfPACK evaluation and development including a reference design, evaluation test fixture, and system test report.
