Hi,

I need better version of schematic. The file in the user guide is not so clear.

By the way, can we use one ISO5852 to drive two IGBT in parallel? Anything especially layout need to pay attention to?

Hi Howard,

Please see the attached .pdf version of the ISO5852SDWEVM-017, below.

A BJT buffer is added at the output of ISO5852S to increase the current drive strength for paralleled IGBTs. Please see this reference design which uses ISO5852S for that exact purpose: "Gate Driver Reference Design for Parallel IGBTs With Short-Circuit Protection and Current Buffer".

Regards,

Audrey
