I was quite impressed with this driver… until… I switched from one of the little gear head motors to a window “regulator” motor (the gear head motor that drives a car window up and down). I tested the motor beforehand. Under load (nearly stalled) it draws a little over 1A.
I had the CS enable while I was using it and the current never went over 1A. However, when I reversed the direction of the motor I got a pop and the magic smoke came out… The L298 literally exploded.
I’m assuming this is a back fly-back problem? Can someone confirm? How can I avoid this? I thought this board had the right diodes on board.
No public wish lists :(
