For the ENABLE pin of this device, what are the absolute maximum rising and falling thresholds for the function? The data sheet shows a range for VEN rising from 1.7V to 2.0V, however nothing is shown for the VEN falling. A graph on page 10 (FIG 6) shows the EN threshold v temperature indicating the falling threshold to be approximately 1.35V. Nowhere else do I find that number.

What you are looking for I think is the VEN_HYST parameter just below the VEN rising threshold. The rising threshold minus the hysteresis voltage is the falling threshold.

That is what I thought. Just to make sure: From the data sheet: I would then calculate 1.7V -.55V = 1.15V as the worst case falling threshold and 2V as the worst case rising threshold, correct?

That is the way I understand it. I do not support thLM53601-Q1 directly though.
