Hi,
I'm in need of some MOSFETs.
I need both P and N channel, ideally "matched". (Similar ratings, don't need to be perfectly the same.)
The motor I'll be driving is:
https://www.arceurotrade.co.uk/projects/stepper/36N%20AC420484610M.pdf
Note that the current rating, 1A/Phase, is per phase and will need to be doubled. I.e. 2A.
The motor will be controlled through PWM at around 20-35KHz. The driver will be of H-bridge design, if that matters.
A low Rds would be nice.
A gate voltage of either 5V or 12V would be nice. (Either are fine, or within that range.)
The MOSFETs MUST be quite cheap and available in the UK. (Or shipping to the UK is cheap.)
I did look at part number LMD18245, but at £10 each it's way too much. I need 6 pairs of these.
I also need a MOSFET pair for these motors:
https://www.arceurotrade.co.uk/projects/stepper/180N Met AC570764525M.pdf
(2.5A/Phase, so 5A.)
I need 12 pairs of these, so obviously it's even more important for these to be cheap.
Thanks for any help,
-Andrew.
