Hey Team! First page of datasheet makes me think yes, I can power from SDQ with a 1.8V pulled up.

Typical application equations make me think no, we need >= 2.0V pulled up into SDQ

Thanks!

I would recommend the additional voltage if its available, but the datasheet text does not forbid customers from using bus powered operation with less than 2V. There is an equation provided for this situation.

thanks,
