hello i am looking for some circuit design work to be done. I need a stepper driver for a cnc machine. i currently use the SLA7078MRP chip but they are slowly becoming obsolete. i need a low-cost solution to replace this step/direction chip for a CNC machine. i need to find a cheap chip that is available on the market and with the following attributes circuit for one motor (unipolar stepper not bipolar) 3-4 amps the least amount of space and number of components no SMDs (or a solution already integrated into a board). This must be cheap as or cheaper than our solution now so a choice of chip is important.
