TS5A9411 leakage current with V+ = 0V

Other Parts Discussed in Thread: TS5A9411, TS5A12301E

Hi Folks,

Can you please confirm that the leakage current between NO pins 5 & 6 with V+ = 0V (V+ tied to GND) will be less than the 3nA specified in the datasheet when V+ = 5V?

Thanks.

    Carlo,

    The TS5A9411 doesn't have the powered off isolation protection feature.  This is why you do not see a leakage spec for the signal path when the device is powered down Vcc= 0V.  If you would like a device with this feature you can search the ti.com signal switch selection to for the additional feature called Ioff or Ioff protection. 

    For example the the TS5A12301E has this powered off isolation protection feature and you can see the spec you are asking for specifically called out in the datasheet.

    <3nA leakage current is very low why do you need to have this low leakage when the device is powered off? 

    Thank you,

    Adam

    Thanks Adam,

    The TS5A9411 was to be used as the ON switch for a miniature disposable data logger powered by a small button battery.

    Regards, Carlo.
