I have designed a stepper motor driver ckt using L297 and L298 and it works properly, but here is one problem that at start-up when i switch on the power my ckt behaves like short and draws maximum current, and stepper motor does not move smoothly, when i start and stop motor 2 or 3 times, it comes in its original condition and take a normal current which it needs to move smoothly.
actually i am driving 3 motors at a time.
Due to this reason at start up because of excessive current my circuit got damaged many times. what might be the reason behind this............?
Help me please........
The schematic is attached herewith.
