Hello experts
I generally know next to nothing about MOSFETs, and I'd like to study up so I can use one as a switch in an application, but before I jump into it, I have one question:
Is it possible to get a MOSFET which is open when there's no charge on the gate, which will switch fully on/off with only TTL on the gate, and which will conduct upwards of 25A at up to 12V continuously? Or am I dreaming?
I need the MOSFET to turn on a brushed motor on and off with a processor output or similar. Nothing fancy, just stop or full speed ahead.
If my question needs clarification, please just ask, and I'll answer my best.
As for your answers, I don't need much. Yes/no will suffice, a component type suggestion as well would be nice, and in the event that one of you feel like educating me, that will just be a great bonus. Good links are also very welcome.
Thanks.
