current consumption 0.16 Amps.
Can i supply my Arduino Board with my external Power supply 9 Vdc, and take my supply from Vin of my board, pass through coresponding resistances through my MOSFET and up to my FAN without hurting my Arduino ?? Please note that i will like to control my FAN with PWM in relation to a thermistor.
Basically yes - be sure it's a logic-level MOSFET (that can be switched with 5V logic - most require 10V). The 5V fan might run a bit fast on 9V - so you are adding a resistor to drop the voltage a bit? You would normally do that on the high side, and switch with a n-channel MOSFET or NPN transistor on the low side.Is the fan a brushless motor BTW?
Quotecurrent consumption 0.16 Amps.That's like nothing. A puny to92 npn or 2n700x will handle that with ease.
