Where did you find the Vgs value of 10V? I can't seem to find it on the Datasheet.. maybe I'm not looking for the right attribute.
Is it possible to use a separate driver circuit to provide the required Vgs?
To use a MOSFET as a switch, you have to have its gate voltage some voltage (Vgs) higher than the source. If you connect the gate to the source you are ensuring the MOSFET is off (Vgs=0).
I made a mistake there.. the gate should be connected to the drain shouldn't it?
Hi, What supply voltage(s) do you have available, in addition to +5V??What is the voltage you want to put across your coil when it is active?
No, it really shouldn't. Here's a basic circuit that uses an N-channel logic-level MOSFET as a switch (which is what you are doing):http://ruggedcircuits.com/html/circuit__7.htmlThe gate is connected neither to the drain, nor the source. The 47k resistor is there to bleed any charge that accumulates on the gate through leakage paths.
