Part Number: DRV8886 I am thinking of using DRV 8868 with noncircular 1/2 step.
However, the output waveform does not rise when using noncircular 1/2 step. (See Attachments) The rise time varies depending on the Alumi Capacitor . Is the capacity of…

Part Number: DRV8886 Hi,
I am using the DRV8886 to drive a stepper motor. The stepper motor drives a gear-train and move a acme screw. I would like to know the DRV8886's behavior when the stepper hit a hard stop. Would the DRV8886 announce a fault?…
Part Number: DRV8886 Other Parts Discussed in Thread: DRV8424 Hi all
My customer is working on a new design where they need a stepper motor driver with nominal specs:
24V / 1A ... 2A (max operating should be more than 30V)
What product would you…
Hi Wang,
Following table shows wire resistance.
DRV8813 is lower Rds_on than DRV8886 and both wire resistances are not so big difference. Therefore DRV8813 should be higher torque because lower Rds_on make the winding current a little bit higher and…
Part Number: DRV8886 Hello,
I can see in the DRV8886 datasheet two grounds (GND and PGND). As far as I can see PGND is the lower voltage of the H-Bridge but I still have the following doubts:
- Could I connect GND and PGND to separate grounds in…
Part Number: DRV8886 Hello,
I have the following questions related to the right performance of the bulk capacitor and the suitability of this capacitor in small PCBs.
- Is it necessary to use an electrolytic capacitor? Could I use one or several…
