I plan to drive the PSU for an SSD drive (about 400mA) from a port line (0 -> 5v)
I would like to do it with an N MOSFET.
My problem is I don't understand if i should put my MOSFET between +VCC and SSD psu or between SSD gnd and my gnd (thus my gnd will be over 0v than Vgsth...
MCU is powered with VCC and SSD with VCC (5v), I fear MOSFET Vgsth
Last, does this is suitable, instead of a MOSFET: http://www.farnell.com/datasheets/1499915.pdf?
Or do you see a better solution?
Thank you!
