Hi Jacky,
If the COM node can be seperated, then, it can be driven by DRV8825.
If not, you can use DRV8803 DRV8805 or DRV8804 as you want , the interfaces are different. Note this is a voltage driving motor without the need of current regulation…
Hi Binu,
TI has a few devices designed to drive unipolar stepper motors (DRV8803, DRV8804, DRV8806, DRV8844). None of them have microstepping built in.
Part Number: DRV8935PEVM Other Parts Discussed in Thread: DRV8935 Tool/software: Dear TI team,
I’m using the DRV8935 EVM and have some questions regarding its compatibility and configuration when driving a unipolar stepper motor .
The motor is…
Hi Patrick,
I'm Matt from the Motor Driver team!
Presently, we have devices such as the 4-channel DRV8844 (4x 1/2-H bridges) or the 4-channel DRV8803 (4x low-side drivers), and several others that can drive a 24 V output.
What are the requirements…
Hi LI Iwan ,
The DRV8803, DRV8804, DRV8805, and DRV8806 can drive the motor. Other bipolar stepper motor drivers like the DRV8846 or DRV8884 can also be used if the motor is connected in a bipolar configuration.
There are a few questions about the…
Gamze,
The thermal performance is relied on the PCB layout a lot. The datasheet gives the thermal resistance.
The power loss can be estimated by Rds(on) x Load current x Load current.
After we know the power loss and the thermal resistance…
Hi Vibhuji,
Yes the device can be used for lower currents. The current specified is typically the maximum current through the device.
There are a few other devices that could be considered. The DRV8860, DRV777, DRV8803, and DRV8804 may also be suitable…
Hi Hirotaka,
Flyback is something a voltage pump caused by the recirculation current. You can refer to the following blog for some idea.

If there is no diode inside TPL7404, you will must need external…
Hi Shreenidhi,
How much current is required?
The DRV8804 will work as shown as long as the VM voltage is above 8.2V. Other options are the DRV777, DRV8803, DRV8805.
Have you considered configuring the stepper motor as a bipolar stepper? This…
Hi Arhez,
Yes. if you have a 6 wires unipolar motor, you can drive it with bopolar driver in a scheme that the two center taps are floating.
Also, we have drivers such as DRV8803, DRV8804, DRV8806, DRV8860, DRV8805 for unipolar motors.
Here are…
