Hi all
I have a set-up (made with help from you guys) where an IRLZ44
MOSFET is switching around 40V and is turned on by a controller
with a 5V signal. I made a mistake(!) and forgot to connect the
ground between the MOSFET circuit and the PSU, which resulted
in the IRLZ44 shorting and sending 40V into the controller. It smelled
for DAYS, and was of course fried. So, I'm thinking about adding a
fuse to take the chill instead of the controller if I mess up again.
So my question is, what value should it be, and where is the best
place for it? On the gnd wire from the MOSFET circuit going to the
controller?
Thanks a lot!
