Part Number: LM74670-Q1
One of my customers is considering using LM74670-Q1 for their next N+1 redundant power supplies system.
They are going to have several products which can support to 3V~25V voltage range.
They were looking for TI ORing device for it and found LM74670-Q1, smart diode IC.
Can LM74670 be used for ORing of N+1 redundant power supplies system which has 3V~25V voltage range?
If LM74670-Q1 can not be used for the system. could you please tell me any other TI device?
Your reply would be much appreciated.
We recommend our new devices LM74700-Q1 for ORing N+1 redundant power systems.
LM74700-Q1 is better than LM74670-Q1 because LM74670-Q1's output voltage has a pulsed behavior and may not be suitable for all systems.
For ORing applications, we request to you to refer to the datasheet application section 10.2 or the application note section 8 "https://www.ti.com/lit/an/slvae57/slvae57.pdf"
Let us know if you have further questions.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Karikalan Selvaraj:
Thank you very much for the prompt reply.
Could I ask you an additional question?
Their power supply voltage range is 3.0V~25V.
Can LM74700-Q1 operate correctly at 3.0V input voltage?
Thank you again and best regards,
In reply to Kazuya Nakai59:
LM74700 can operate upto 3.2V.
If you require 3V operation we recommend to use LM74800-Q1 device which supports 3V to 65V operation.
Thank you for the information.
It seems that the device is still under developing.
Do you know when the device release date is?
We need to take discussion about release dates offline via email.
Can you share your email id?
Please share your email id, so that we can take this discussion offline.
Thank you for your reminding.
I sent a message to you via friend request system last week.
I will send you it again.
I have sent an email to you on the release timeline for LM74800 and would like to close this thread if you have no further questions.
