I've a strange issue. I wired everything up like that:
The ATTiny13 changes, for test purposes, every 10 seconds between HIGH and LOW. Since the IRF3708 needs 2.8V to switch state, I use the 5V "power line" with a transistor to get over the threshold.
FYI: This is not my whole project; but it must work as a single component. After all, some may think "he doesn't need this part at all" - I do :)
This setup works - even the 10s cycle etc. But when I measure between source of IRF3708 and GND - there is only 3V on my multimeter.
When I measure between Drain and GND, it is my 24V. So it seems that the IRF3708 is "swallowing" 21V while running through it.
I hope the problem is clear and you can help me.
Thanks a lot already!
