Wolfspeed Partner Designs

Cree | Wolfspeed is a global leader in wide bandgap semiconductor technology. Wolfspeed’s silicon carbide MOSFET portfolio offers the industry’s lowest on-state resistances in a discrete package as well as low switching losses, enabling high efficiency and power density. Wolfspeed SiC devices far outperform conventional silicon components and set new standards for efficiency and reliability in industrial, energy, automotive, and consumer markets. In partnership with Wolfspeed, Silicon Labs offers a range of innovative and proven isolation solutions tailored to these world-class SiC devices.

Wolfspeed WolfPACK™ Module Gate Driver Boards

Silicon Labs' Gate Driver Boards (GDB) are ideal for driving power modules from Wolfspeed, such as the Wolfspeed WolfPACK power modules. These two-channel isolated gate driver solutions feature a differential digital interface, optimized on-board isolated power supply, and user-configurable turn-on and turn-off gate resistors. Status indicator LEDs and test points make evaluation and prototyping easy. These GDB are compatible with Wolfspeed’s Clamped Inductive Load (CIL) test fixtures for controlled and comprehensive module evaluation.
