LM74700-Q1: ORing architecture for 12V/24V application

Ann_Lien

Part Number: LM74700-Q1

Hello expert,

If we have one 12V to 24V power path (as power mux) application, can we use two LM74700 to achieve it as following figure?

(12V/24V, 1A)

Best regards,

Hello Ann Lien,

In this configuration, whenever 24V supply is present it will supply the load naturally.

With this ORing highest power rail (large voltage) will power the load.

We don't external control to turn on/off using enable pin.

However in this approach does not work for priority power mux.

Regards,

Kari.
