Silicon Labs and Wolfspeed partner to deliver power module solution

Silicon Labs has introduced the new Si823Hx Gate Driver Board, an all-in-one isolation solution designed for the recently launched Wolfspeed WolfPACK power module. Wolfspeed power modules are used across numerous power applications, including EV chargers and motor drives. The board features the Si823Hx isolated gate driver and Si88xx digital isolator with an integrated DC-DC converter.

“Power electronics engineers face many challenges when designing high-power systems, from space constraints to safety requirements,” said Silicon Labs VP Brian Mirkin. “The Silicon Labs Si823Hx gate driver board is an efficient, high-performance solution designed to simplify the development of systems using power 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 EV chargers. The Si823Hx gate driver board is designed to drive and protect power modules employing any switching technology, including advanced silicon carbide (SiC)-based modules.

The two-channel Si823Hx isolated gate driver includes built-in dead-time control and overlap protection in a small package, enabling it to drive a half-bridge topology. The integrated Si88xx device communicates power module temperature to the controller and generates all the power for the board.

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