TS5A3159A: Isolation in Power-Down Mode

Part Number: TS5A3159A
Other Parts Discussed in Thread: TS5A3159

Dear, support Team.

TS5A3159A has Isolation in Power-Down Mode, V + = 0.
Does this mean that voltage can be applied to the input even when there is no power supply voltage?
Absolute maximum rating input is up to Vs + 0.5V.
But this is the same as the A-less version of TS5A3159.
The characteristics of Off isolation are the same.

Best Regards

    Hi Hiroaki,

    Thanks for using our e2e forum.

    The performance in the recommended operating conditions and electrical specifications is supported by TI.  You can see that TS5A3159A supports isolation when V+= 0 in the leakage spec.  The abs max condition would apply to cases where V+ does not equal 0V.  

    Please see another e2e post at this link that explains the TS5A3159 and TS5A3159A behavior in Power-Down Mode, V + = 0.

    Thanks

    Hi,Saminah-san,

    Thank you for your reply and advice.
    I understood the meaning of isolation when V+= 0.

    Best Regards,
