Other Parts Discussed in Thread: UCD7242
I am using a UCD9222 to sequence/control a UCD7242. Normally the design works fine but I am finding a few units that for the B side of the UCD7242 it will not work unless the USB adapter is connected at power up. If I have the USB adapter connected and power the board it boots up fine. If I don't have the adapter connected and power up the B channel on the UCD7242 does not start. If I then connect the adapter the GUI reports a fault on the B channel. If I do a soft reset in the GUI of the device it powers up fine.
