DRV5053: DRV5053PAQLPGMQ1 & DRV5053PAQLPGM, any difference ?

Hissy,

Welcome to E2E.  Thanks for reaching out with your question.  The difference between the two devices is that DRV5053PAQLPGMQ1 is an automotive grade variant.  This device undergoes production tests and qualification processes that allow for the difference in grading.  Typically, there is also a wider operating temperature range, but we do see that with the Q which preceeds "LPGM" in the orderable name that the temperature grading for this device is the same.  

Commercial Grade

Automotive Grade

Functionally, the two devices have the same operating specifications, so the primary difference is just the higher level of qualification testing for the automotive grade.

Thanks,

Scott
