MMPF0100 for 100% duty product.

[satoshishimoda]

Hi community,

I want to your advice for selecting appropriate MMPF0100A for i.MX6.

Please see Table 1 of MMPF0100 datasheet (Rev.9.0).

There is "Qualification Tier", but we did not understand it well.

For i.MX6, we can see AN4724 and AN4725 for lifetime estimation, but we could not find similar document for MMPF0100A.

If there is a similar document for MMPF0100A, would you let me know it?

And if there is no similar document, would you let me know which "Qualification Tier" device should customer use if their product's duty cycle is 100% (24 hours, 365 days).

I guess the difference between "Consumer and Industrial" and "Extended Consumer" is temperature range and package, so I think customer use both chip for 100% duty product.

Is this correct?

Best Regards,

Satoshi Shimoda

Hi Satoshi

I am afraid similar document as AN4724/AN4725 lifetime estimation

is not available for MMPF0100A. You are correct that customer can use

both chips ("Consumer and Industrial" and "Extended Consumer") for 100% duty product.

Best regards

Hi igor,

I want to confirm about 100% duty for auto chip "MMPF0100AZ" also.

I feel MMPF0100AZ is not able to be used for 100% duty since its qualification, right?

HI Staoshi

I would suggest to create Service Request for that,

so appropriate expert could answer on it.

Hi igor,

Thank you for your reply.

I want to confirm life time when use them 100% duty to make sure.

Can both chips  ("Consumer and Industrial" and "Extended Consumer") work 10 year with 100% duty?

Hi Satoshi

I am not aware of official documents regarding "life time",

but its FIT numbers are better than i.MX6.
