Hi Adam,

Are you talking about having a FET Driver daughter board that would have the all the MIC4451 circuitry for a single 100A module ? and a common input (Molex connector) from the HCPL-4504 for how ever many modules used ?

You could still use your existing 5x or 7x FET Diver PCB’s. Instead of single 100A-120A module, design a (5x) Power PCB (500–600A) that your 5x FET Diver PCB could connect to. You could then use multiple (5x) Power PCB's to expand from 500-600A to: 1000-1200A, 1500-1800A, 2000-2400A, etc…. ??? and make the Molex connector on the controller handle the additional Driver PCB modules.

At what frequency does the PWM operate ? do you use wire or coax for connecting the controller PCB to the FET driver PCB's ???

?????
