Hello,

Yes, LM74700-Q1 device capable of reverse polarity protection, rated at 65V DC max.

Is 450V DC nominal operating condition or is it a transient condition?

Could you please let us know more about the application, is it industrial or automotive battery or other applicaiton?

Regards,

Kari.

Hello Kari,

450VDC is the normal operation. It will be automotive battery.
If there are no solutions available, i will go with a standard MOSFET setup.
