Hello,Originally posted by xairflyer
I have a driver board made up using a 5804 that I am experimenting with.
The IC can drive 1.25 amps on it's own but I have found anymore than 1 amp it gets fairly hot.
I was going to add power transistors or fets to the outputs so I could drive larger steppers, anybody got any views on this ?
Piece of cake. Done all the time with the 5804; it's even on the datasheeet. LOTS of mfrs. use the 5804 for it's translator, and up the drive capability with external drivers...
Hope this helps,
