Hello to everyone. I just want to know if there is any way to increase current capability at the output of IR2101 gate driver.
Suppose I have various power mosfets in parallel to handle a huge ammount of current, in this case the gate driving current will also
increase. Is there any way to do this without using another gate driver?

Best regards and thanks in advance. Yosmany.

Hello Yosmany,

Yes, to add some additional components can increase the drive current capability, please refer to the below application note for details:

But we would suggest you to use another gate driver IC, it is more easy, for example, IR2110.
