I have a project I'm working on that requires me to switch a lot of current, roughly 1 amp or so. I posted on here a couple weeks ago with a bjt design, but under some guidance from some memebers, using a power mosfet makes a lot more sense. I just want to make sure my design makes sense so I can hurry up and order these parts.
I'm switching 1 amp roughly, but to use the mosfet as a switch the optimal goal is to operate in the mosfet's triode region of output characteristic. I need to satisfy Vgs>Vth and Vgs-Vth>Vds, and looking at the datasheet, if I allow my Vds = 0.1V that will allow for 1amp of drain current. My question is about the graph of Vgs vs Id. It states on the graph Vgs =10V. How would I calculate how much Vgs I need to apply to achieve 1amp of drain current? The max I can apply is 5v to the gate. It looks like roughly 3V according to the graph, but is that assuming Vds = 10V?
Thanks once again for all the help!
