    Hello Vincent,

    The DRV8871 has internal current sense.

    The DRV8872 has current sense externally through the Rsense resistor.

    The DRV8872 has a fault reporting pin. the DRV8871 does not.

    The  DRV8872DDARQ1 is  automotive qualified part of the DRV8872DDAR. In general, having the Q1 at the end means the part is automotive qualified. 

    I hope this helps.

    Thanks.
