I am thinking of a combination of ADuM4135 and SiC MOSFET.
Since the output current of ADuM4135 is insufficient, we are considering adding a buffer.
Do you have a reference circuit or application note for ADuM4135 + buffer?
I don't have a reference circuit readily available for the ADuM4135 + buffer, but I am curious what gate charge and rise times you are hoping to achieve. The ADuM4135 is marked as a 4 A driver…
A peak current of about 8A is assumed.
SiC : Qg = 1150nC, Internal Resistance = 1.2ohm , External Gate Resistance = 1ohm
I expect a fast rise time.
Gate_sense pin connects directly to the gate of…
