LM5060: LM5060 usage in ORing configuration

Hi Chris,

LM74700-Q1 would be the right device for Oring configuration. Please go through the datasheet and let us know if you have any further questions.

Best Regards, Rakesh

For sure LM74700-Q1 seams to be a good ideal diode controller. 

But I want to avoid an additional chip and want to use LM5060 for its MIN/MAX input voltage control capabilities.

So what will be the behavior of LM5060 if another power supply is feed at its output through a diode?

Hi Chris, Can you share your system block diagram with details on the protection requirements to understand and suggest right solution. Do you need over voltage and over current protections in addition to oring? Best regards, Rakesh

Hello,

I've a lot of constraints in this design and they are related to component sharing with other designs. That's why I need to know if a solution based on LM5060 is suitable before looking to other components.

Could you please provide an answer to my question: could I use the LM5060, with the Example 3 schematic from the datasheet, in a ORing configuration with another power source connnected to the output using a diode?

Hi Chris,

ORing controllers blocks reverse current (always) like a diode but LM5060 with back-to-back FET configuration needs to be disabled to block the reverse current. LM5060 is not suitable for active Oring application.\
