Other Parts Discussed in Thread: DRV8904-Q1
Hi, Team
1. The back-EMF of stepper motor could be read no matter stalling happens or not.
2. Constant Voltage Drive mode is available under the Full step or Half step driving conditions.
3. Constant Current Drive mode is available under Micro stepping condition and the Constant Current could be regulated as we want.
I need to examine the 24stepper motor and do not know DRV8889Q1 can satisfy those requirements or not, if DRV8889q1 cannot, what IC of TI can take these?
Best Regards,
Leo
