Reference Design

This is a picture of Gate Drive for SiC MOSFET Module.
Gate Drive for SiC MOSFET Module
In recent years, SiC MOSFET modules have increasingly replaced conventional Si power devices in power converters, such as industrial motor drives and railway traction inverters, to reduce size and power loss.
This gate driver is designed to drive such modules safely and includes multiple protection functions. It uses the pre-driver coupler TLP5231 together with external buffer MOSFETs, enabling large gate-drive current while providing isolation for high-current/high-voltage SiC MOSFET modules. The design offers a two-channel configuration (high-side and low-side) on a compact 62 mm × 100 mm board that can be integrated into our Dual MOSFET modules.
We also provide key design considerations, usage and adjustment guidance for each circuit block, along with circuit diagrams and PCB pattern information to support your design work. Note: new designs using 2SC6026MFV are Not Recommended for New Design (NRND) as of April 26.
