Hi Everyone,
I've got a question that's been bugging me for a while now.
I want to build another dc motor control, and this time, rather than using diodes for the freewheel clamp I want to use a mosfet.
The controller will use a HV regulator on the board (good for about 60V) and 75V mosfets that I'll use for the drive side of the circuit. This means I can run either a 12v motor or a 48v motor. I was thinking to use the IRF1405 as the freewheel mosfet.
Now, when I look at this:
It shows the source and the gate connected, but my question is, if I am going to be running a 48v motor, do I need to put some sort of zener on the gate to protect it or keep the voltage at an acceptable level?
Thanks for any and all advice
