I am a university student and I am tackling a project in which I need to control a stepper motor, for various reasons that I am not going to mention I cannot buy the integrated circuit necessary to control said motor so I decided to recycle an old integrated circuit from a disk reader of a laptop, the TPIC1356 manufactured by Texas Instruments, the problem is that the information on said circuit is not available anywhere, not even on the manufacturer's website. That said, I would greatly appreciate any contribution of information on said circuit or any circuit. similar one that can guide me to make the necessary connections to use this circuit in my project
