adum1310 as Logic Level MOSFET Driver

Hello!

 

We use 3x IRLL110 MOSFETs for 30kHz load switching and currently drive them from 5V 74HC04 logic NAND gate.

As for now we need to add galvanic insulation by driving IRLL110's gates directly from adum1310 outputs (we use 5V supply on both sides).

How do you think could the adum1310 just provide the same perfomance of gate charging as 74HC04? Or it would be significantly better to enforce adum' outputs before apply them to logic-level MOSFET' gate?

 

Thank you!

Alex
