Hi, I'm using the 1EDI60N12AF to drive a SiC MOSFET with a bootstrapping circuit as a high side switch. The Datasheet lists 'Short Circuit Clamping' stating additional circuitry need to be connected to the 'Out+' pin but I can't find any reference to this in any of the application notes, they all reference the DESAT pin, which is not on the 1EDI60N12AF.

Could you please provide some guidance as to how to add short circuit clamping to the 1EDI60N12AF IC gate driver using the OUT+ pin. Below is my gate driving circuit + the short circuit clamping information provided in the 1EDI60N12AF datasheet.

Thankyou for your help!

Kind regards,

Toby

Hi Toby,

 

  Please refer section 3.3 of the following Application note,

https://www.infineon.com/dgdl/Infineon-1EDI60I12AF_EVAL-ApplicationNotes-v01_00-EN.pdf?fileId=5546d4...

 

Please do let me know if the explanation in AN has helped you in designing an output short circuit for the required gate driver.
