Hello, all

Now we have one inquiry regarding unused SENSE pin on TPS386596 from our customer.

Please refer to the item below, and feedback us with your comment.

On previous support, we understood that the unused SENSE4 should be pulled up.

Please let us clarify whether the SENSE1(3.3V) could be pulled up to VCC, incase this pin is unused.

We thank you once again for your information.

Best regards,

Okui-san,

Yes, any of the SENSE pins that are not being used ("don't care") should be pulled up in order for /RESET to be released.

Very Respectfully,

Ryan
