Team,

Can the LM74700-Q1 drive FETs in a -48V configuration. The customer wants to replace the GE PIM400. See blockdiagram below:

LM74700 is not suitable for negative ORing, but LM5051 is negative ORing controller.

But if you wish to use LM74700-Q1 on the GND side with -48V common bus then it can work.

Could you share more light on this one?

Regards,

Kari.
