Not sure what the issues is but when I apply power. I don't get the 3.3 VDC out to run the hall cells.

    Hi Ryan,

    In your DRV8306 schematic I noticed that you tied the DVDD regulator output to the Enable pin. At start up the DVDD regulator is disabled in sleep mode until the device's Enable pin is pulled high, since the Enable pin is tied to DVDD this will keep the device in sleep mode and prevent the DRV8306 from being able to exit sleep mode.

    Please supply an external logic high input to the enable pin to wake up the device and enable the DVDD regulator.

    Regards,

    Joshua
