LM25066I: /SMBA response time

Ann_Lien

Part Number: LM25066I

Hello expert,

May I know the response time for /SMBA when fault/warn occurs? Customer need response time smaller than 20us and I cannot find the answer from datasheet and EVM user guide. Thanks a lot!

Best regards,

Hi Ann,

The response time of SMBA has not been characterized. Considering that the delays are caused only due to the internal gate structures, the delay should be very minimal around or less than10us.

Can you please ask customer to test this on EVM.

Hello Praveen,

Thanks for reply. I've already apply EVM for them but they need to confirm solution by this week. Could kindly help to do a quick test on EVM? I don't have LM25066I EVM on hand too. Sorry for the inconvenience and thanks a lot!

Best regards,

Ann Lien

Hi Ann,

We have very limited access to labs due to current situation related to COVID-19. We are not sure when the situation here eases and I can access lab.

Therefore we recommend that customer perform these tests on our EVM in their labs if possible.
