Part Number: DRV8886AT We are using the DRV8886AT stepper motor driver in a fairly critical application. The stepper motor may be in sleep/disable mode for long periods of time but when we do need to drive the stepper motor we need to be fairly confident…
Part Number: DRV8886AT Hi Team,
Are the DRV8886AT PGND and GND tied internally? My customer is trying to figure out which from their system to use for each - they have the direct battery ground for power return and a filtered digital ground.
Thanks,
…
Part Number: DRV8886AT Dear Expert,
As title, does DRV8886AT support back EMF protection?
I found we have "7.3.4 Current Regulation" in datasheet which mentioned back EMF function, but we would like to double check this protection with you if we can…
Part Number: DRV8886AT Hi all Would you mind if we ask DRV8886AT? On the DRV8886AT's datasheet, there is the Table7. <Question1> What does SINE INDEX indicate? microsteps?? <Question2> And then, XX% means curren value, right? Kind regards, Hirotaka…
Part Number: DRV8886AT Referring to the datasheet section 7.4, there is a note to hold STEP low while coming out of nSLEEP or when applying power. The question would be does STEP need to be held low while the device is in the SLEEP state, or can the device…
Part Number: DRV8886AT Hi
I need to check:
1.TI DRV8886AT can connector to Marvell MCU 88DE3006 ?
2.what is the STEP/DIR control method?
Thanks

Part Number: DRV8886AT Hi
Our customer is evaluating DRV8886AT and see the below phenomenon. Could you kindly advise why the phenomenon was seen and how DRV8886AT control at high speed range.
Operating conditions - Motor : 2,000 pps -> 18,000pps (increasing…
Part Number: DRV8886AT Hi all Would you mind if we ask DRV8886AT? We recognize as follows; <AutoTune Dynamic Decay> Off time = Fixed off time PWM frequency = Fixed PWM frequency <AutoTune Ripple Control> Off time = Auto adjustable off time PWM freque…
Part Number: DRV8886AT Dear Support team,
Our customer will use DRV8886AT in their application. They use the DIP switch on the RREF pin of DRV8886AT to select the current limit values. What happens if the DRV8886AT's RREF pin is opened due to a mistake…
