Hi ,
I found that TI has a Application Note document "sloa312(How to Drive Unipolar Stepper Motors with DRV8xxx)" , as attached
How to Drive Unipolar Stepper Motor with the DRV8xxx (ti.com)
Which mentions 3.3 Driving Unipolar Motor with Four-channel Half-Bridge Driver
In addition to the DRV8xxx Half-bridge Drivers listed in Table 3-3,
Can I use DRV8846 Dual H-Bridge Stepper Motor Driver to design drive Unipolar Motor?
If I can drive Unipolar stepping motor with DRV8846,
How to design the connection circuit with DRV8846 and Unipolar stepping motor with the following architecture.
Thanks
Jack
