[DRV603] different TA temperature range

Other Parts Discussed in Thread: DRV603

Hello~

According to DRV603 datasheet, TA value of "ORDERING INFORMATION" and TA value of "RECOMMENDED OPERATING CONDITIONS" have different range.

I think one of those is typo.

Please check.

Thanks... C.W. :)

    Hello, C.W. The TA at the top of the page refers to the temperatures at which the IC can be stored (assumes the IC is not operating, or even on the board). The TA at the bottom of the page refers to the ambient temperatures that we have used to characterize the operation of the part. For this reason, it's not a typo, it's just a poor choice of nomenclature on our part.

    One way you can tell that a temperature range refers to storage temperatures is by the –40 °C temperature at the lower end. Also, that section refers to rail and tape and reel characteristics, indicating the IC is not on the board. Most parts are only characterized to operate down to 0 °C.

    Best Regards,

    Hello, Matt~

    Thanks for your reply.

    I have one more question.

    According to your reply, I understood that TA value of "ORDERING INFORMATION" means temperature at which the IC can be stored (assumes the IC is not operating with rail packaging or tape & reel packaging).

    And then, what is difference between Tstg value of "ABSOLUTE MAXIMUM RATINGS" and TA value of "ORDERING INFORMATION"??

    Please define the difference.

    Thanks... C.W. :)
