TPS62231-Q1: the difference between TPS62231 and TPS62231-Q1

Hazel Sun

Part Number: TPS62231-Q1

Hi all,

I noticed that for the maximum operating junction temperature, TPS62231 is better TPS62231-Q1, the Q version is generally better, is this the specification book wrong? Thanks

Hi Hazel,

Automotive and commercial device has different manufacturing flow (reliability, different temp cycles) and device is characterized accordingly.

This the reason for different junction temp range.

Can you share more information if it is affecting the end application ?

Best regards,

Tanvee

Tanvee,

thanks for the reply, you means that different manufacturing flow decides the different junction temp range, so the spec is correct, if customer want to use nor-Q in place of Q, which parameter needs to be considered

Hi Hazel,

Auto and commercial devices share same design architecture and expected performance is similar. You have to give attention to parameters suggested in the datasheet. Both device recommended temp value is same and only difference I find is the absolute value which is normally not recommended to use for normal application.

I would not expect there is any critical issue to switch to Q part from commercial part. Please let me know if you have any feature concern here.

Best regards,

Tanvee
