Hopefully I am on the right subforum. I just want to clarify this basic idea, of which I know nothing, and want the ones with the knowledge to share them.
I have been reading a lot about BJTs and FETs, MOSFETs, Logic Level MOSFETs. Basically this is for switching motors on/off, not controlling the direction.
So, using MOSFET is one effective way at this. The basic idea I want to clarify is the difference, pros and cons between using common MOSFET as opposed to Logic Level MOSFET.
Can someone elaborate on this? 1. One can control the current passing thru source to drain by controlling the voltage at the gate? 2. Logic Level does not control the amount of current, but just turns fully ON and OFF the path? 3. If the Logic does fully turn on the path, so the amount of current flowing from source to drain depends on the current rating of the MOSFET? Say 14A, therefore 14A will flow (thereby one needs resistor )? Or depending on the needs of the motor?
Hopefully the god members will clarify this. Including other parameters to watch out for. ^^
