Alright, so I've been working on I guess what you could call an advanced solid state switch for a high current motor. The input switch allows for a user interface and the photogate allows for the microcontroller to monitor the position of the motor. Because the motor needs to stop immediately once the microcontroller tells it to, I am trying something which I believe is called active braking (or AB).
Here's my problem.
the current p-type MOSFET's cost is just a little high for what it is intended to do in this case .
Does anyone know of a replacement p-type MOSFET that would work in this case and can handle atleast 30A (I've had measured current spikes as high as 20A from this thing)
