Hey,
I have a question for you all. I require a driving circuit for a solenoid (taking about 60 amps from a 12V LiPo battery).
Now, I plan on using two FETs arranged in a half bridge config. Both will be N-type. Now, what is best to drive this solenoid: high side or low side.
I understand that driving N-type on the high side is harder, but chips are available, so it's really not that hard anymore.
I'm assuming that having high side drive might be better for such a high current application, and that it's safer to leave the solenoid connected to ground when it's not on (with a flyback diode parallel to the solenoid for the back EMF spike).
I've been trying to find out more information about it, as I need to justify my choice of high or low side drive. I also know that high side drive is like sourcing current, and low side is sinking it.
Any advice would be great thanks
