DRV8873: Current Detection

Part Number: DRV8873

Hi Team,

Customer would to know whether the two outputs of current detection are detected separately when driving a DC brushed motor? Or is it enough to just detect one AD together?

Thanks,

Annie

    Annie,

    The device has 2 iPropi pins.  One pin monitors current on the high-side of one FET and the other pin monitors current on the other high-side FET (connected on other side of motor).  For bi-directional control, only one current monitor will register current depending on forward or reverse control.

    Please see section 7.3.1.3 in the datasheet:

    7.3.1.3 Internal Current Sense and Current Regulation

    Regards,
