Hello people,
I am constructing a circuit to drive a solenoid using an H-bridge arrangement and would like help in deciding on which MOSFETs to use.
My solenoid is operating at quite a high current. It has a coil resistance of 7.5 ohms and my circuit is operating at 11V, so its a mighty 1.5A. I intend to drive the gates of the MOSFETS from 4000 series CMOS logic in a fashion similar to the circuit described here:
http://www.electro-tech-online.com/viewtop...olenoid&start=0
I currently have these P types:
IRFD9120
http://www.datasheetarchive.com/datasheet....article=1811783
IRFD9024
http://www.datasheetarchive.com/datasheet....article=1811761
and these N types:
IRFD014
http://www.datasheetarchive.com/datasheet....article=1811527
IRFD110
http://www.datasheetarchive.com/datasheet....article=1811541
would any of these do the job? If not can you tell me what to get.
I also intend to use a solenoid which draws 1A from this circuit in the future, will I need to change the mosfets for this purpose or can I just switch out the solenoid?
One last thing, I do not know which pins correlate to the gate, drain and source on these chips (yup I am that clueless), referring to the chip from the top and with the dual pin connection on the left, which connection refers to the gate, drain and source on these things.
Thanks,
Scott
