Hello,
The startup characteristic using an external capacitor on the enable pins seems well defined based on the internal current sources. My question pertains to the source of the pull-up currents. In the block diagram there is a 3.6uA and 3uA source as well as a 1.2V reference. In another post I read that the currents are supplied from the V7V regulator.
Where is the '1.4uA' source listed in figure 28 is from? Similarly, where is the threshold of 0.4V from, before the 3.6uA pull-up current is enabled?
Thank you,
Michael Rosa
