Please find below the schematic of a mosfet based inrush current limiter. It works in simulation (Tina TI) but I would like to get your opinion. Do you think the schematic below is a good approach to address the following requirements? Can you see any issue regarding to devices tolerances for large scale production?

Requirements :

  1. Limit inrush current when hot plugging the circuit
  2. Be controllable with an high impedance low voltage signal (active high polarity)
  3. Have an active discharge, working whether the power source is plugged or not

And this is the transient simulation result: enter image description here
