Hello @absingh,
Please allow me to adda few additional comments:
Yes, that may work, it’s a good thing to try to better understand the operation of MOSFETS. Note that it is difficult to drive a MOSFET with 3.3 VDC logic. May I recommend using this MOSFET as it has desirable gate drive requirements.
As for time constants, please use this tool:
Finally, if you use the PWM techniques as described by @rick_1976, you may want to switch to a Darlington pair as I described in this post:
The RC time constant idea uses the MOSFET in its linear range. This can cause the MOSFET to get very hot if the time constant is long. Also, it may or may not provide the desired soft start action. The PWM technique allows fine control.
Please let us know the results of your experiments.
Best wishes,
APDahlen
