DRV8834: Stepper driver 1-phase excitation

Hi Team,

May I ask for help? Our customer have a concern as shown below:
"Are there any TI stepper motor drivers that has 1-phase excitation mode when running in full-step mode? All I have found are only supporting 2-phase excitation when in full-step mode."

I also tried to look but was not able to find one. Do we have a product that can fit our customer requirement? Please advise. Thank you so much.

Kind regards,
Gerald
