I'm trying to design hot swap controller circuit using LM5069-2, I understand that startup circuit is required when a large amount of output capacitance is used.
I understand that the external dvdt start-up circuit at the FET gate diverts part of that charging current to slow down the rate of startup dV/dt and hence the inrush current gets reduced.
Q1: What is the minimum output capacitance needed while considering this dv/dt start up circuit.
Q2: Lets say for output capacitance around 1500uF, if I use this circuit start up circuit, I see the gate is not completely discharged, it has around 2V across capacitor during turn-off.
I would like to discharge the gate completely (Considering recommended value, Cdv/dt = 1uF).
Q3: For the above Cout, can I use RC network & a high value R parallel to C so that I can discharge the cap quickly?
