TPS3897: Can Vsense have voltage applied be Vcc?

Part Number: TPS3897

Hello E2E,

Can a voltage be applied to the Vsense pin of the TPS3897 before Vcc as long as the 7V_max spec is not violated?  The event should only last about 10ms.

Thanks!

Russell

    Russell,

    This isn't a condition we test for, but should be okay as long as you stay under the normal operating conditions. This is a pulse that is generated on purpose, I'm assuming, is there a reason why? If this is something you can test, let me know, otherwise we can look into it further.

    Thanks,
    Abhinav.
