Hello,
We are currently looking ahead at future options for stepper-motor control and are interested in ST’s longer-term direction beyond L6470 and powerSTEP01.
For our application, sensorless detection of stall, obstruction/collision, and increased friction/load during motion is important. We have also looked at Trinamic TMC devices, which seem to offer more advanced sensorless feedback, but we would prefer to stay with ST if a suitable future device is planned.
Is there any newer stepper-driver IC on the ST roadmap intended to improve sensorless load, back-EMF, stall, or obstruction detection compared with L6470 / powerSTEP01?
And if such a device is planned, is it something expected in the near-to-medium term?
Thank you.
