Hi Guys,
I need to design something that will isolate our DAQ (Data Acquisition Card) for a basic simulation we need to do. I was thinking about designing a mosfet switch, where the DAQ sends some voltage to the gate above the threshold voltage to turn the MOSFET on and 0 V to turn it off. The MOSFET needs to be able to drive a computer fan (resistance is around 7k) and it runs at 160 mA. I was thinking about using common source. Anyone have any suggestions on the type of MOSFET i should be using in order to achieve 160 mA? Any help would be appreciated!
