hi, I am using L298 . I am driving 2 phase stepper motor with 4A. it's the parallel mode. I have parallel stages 1-2 and stages 3-4. unlike fig. 7 in the datasheet. and The stepper motor works well. Does this method damage the IC in the long run?

Welcome, @A.Reza​, to the community!

The datasheet recommends paralleling channel 1 with 4 and channel 2 with 3: the thermal load on the output stages is thus better distributed on the chip.

It works with your design, but the resulting temperatures will be more concentrated (chip hot spots). It is therefore advisable to follow the instructions in the datasheet.

Good luck!
