Tool/software:

Dear TI experts,

My customer considers LM4890 for their new project.

And they have to turn on and turn off using shutdown pin, about more than 500 times a day.

Does It affect to the lifetime of LM4890? My customer is worried about the parts breaking down because of this kind of operation.

Please check this issue. Thanks.

Best regards,

Dear Ivan,

Thank you for your support.

I already check the contents you linked, but there is not contained the information which I mentioned.

-> Is it okay to understand that lifetime is guaranteed even I use the device as what I said? (on and off the device using shutdown pin very very often)

Please check this issue. Thanks.

Best regards,

Chase

Hi Chase,

I think enable/disable of the device is considered normal use case.

Don't have any more information than what's included in there.
