Hi,

I am having trouble finding a suitable half-bridge gate driver IC for a silicon carbide MOSFET power module.

The power module in question is - http://www.rohm.com/web/global/full-sic-power-modules#6

V(GS) is -6V to 22V and ideally source and sink currents should be a couple/few amps.

Any ideas?

 

Did you check out their drivers? http://www.rohm.com/web/global/search/parametric/-/search/Gate Drivers

The last one seems to do what you need.

Other than that there are tons of gate drivers on digikey.

 

Unfortunately they are single channel drivers. Ideally a H bridge driver should be used with a programmed dead-time to prevent shoot-through.

 

I know that Semikron has driver modules for IGBT bridges, like the SKYPER series. But they are probably expensive.

If you want to use a chip I could recommend the HCPL316 because it includes a VCE protection circuit (they are others that do the same though). For this or any other chip the deadtime can always be determined by the logic that comes before the driver. We used these for AC motor drives.

It depends mainly on what you are willing to pay and how much time you want to put in the driver development.
