AMS5812-1000-D Holds the SDA line high and prevents I2C comms

Here is a scope shot of the locked up condition. Controller can’t control SDA line.
None of the devices can communicate with the controller.


We cut the SDA line to the AMS5812 and the micro controller could control the SDA line.
And the controller could get data from the other devices
See scope shot.

When we reconnect the SDA line it goes back to the first scope image.
If we cycle power on the AMS5812, it will work for a while.
This seems to happen to some AMS5812’s and not so much to others.
Any help or ideas on this problem would be appreciated.
Here is a simple connection diagram.

Thanks
