No.That's responsibility of the controller in this design Thanks for the heads-up though!
Yes, I can because I have programmed it NOT to do thatNo.
Somehow I knew you would say that.
Can you guarantee that the controller does not enable both MOSFETs at the same time, especially during power ON and power OFF?
I bet you cannot.
Surely you have heard of Murphy's Law.
As MrChips noted, that schematic may be simpler but it doesn't make it much easier.To make things easier, I created a simple schematic
Thank you for your note, but I can say, I am doing exactly that.
Those mosfets have 40v limit and I can control the input (see the specs I posted earlier)Is the gate protected from voltages higher than allowable? Most MOSFETS have a limit of 20V.
Thank you for your reply. Yes, I was thinking to use a MOV clamping drain-source for each MOSFET.If it is a spike from the coil that is causing it, you can put across the coil: a cap/resistor in series, a MOV, or a TVS.
Have a look into "relay coil suppression for AC circuits"
