DRV8320: GDF and UVLO fault

NY
Expert 3040 points
Part Number: DRV8320 
What is the priority of fault conditions?
If a fault occurs due to GDF and then the voltage drops to UVLO, which fault has priority and which information is notified to the microcomputer?
Will both be notified?

    Hi NY,

    Whichever fault occurs first is what will have priority. The deglitch time for VM_UVLO is 10us typical, and for GDF is dependent on the TDRIVE time of the device. It should be easy to tell which fault occurs first if you have a SPI device, but may be more difficult to determine on a hardware device. 

    Thanks,
    Aaron
