Part Number: DRV8824-Q1 Hello.
We inherited a DRV8824-based design and are having problems driving the attached motor smoothly. VM is 28V, we only vary STEP and DIR, and the step rate is really very slow -- never higher than 500 steps/sec. Bulk capacitance…
Part Number: DRV8824-Q1 Other Parts Discussed in Thread: DRV8899-Q1 , DRV8824 , DRV8889-Q1 DRV8824-Q1 is an old model a few years ago, We are now looking for an updated and lower price AEC-Q driver. The following are application scenarios for drivers…
Hello Andrew,
Thanks for the follow up.
Andrew Kalman said: All of the current waveforms in the 'scope captures are for the individual windings -- there's a current probe on each winding in the 'scope captures
Yes. Thanks for the clarification.…

In the motor stopped, how to eliminate the abnormal waveform at output pins for the below figure? Could you please advise some…
Part Number: DRV8824-Q1 Other Parts Discussed in Thread: DRV8824 Hi expert,
Customers use DRV8824 to drive stepper motors, occasionally motor rotation direction and DIR set direction are inconsistent.
below is test scope:
The first 12 segments were…
Part Number: DRV8824-Q1 Hi,

Part Number: DRV8824-Q1 Other Parts Discussed in Thread: DRV8824 The motor driver chip DRV8824 is set to 1/2 phase, and the software input STEP is fixed to 12PPS. However, the number of steps is inconsistent at the output of DRV 8824 (The actual number…
Part Number: DRV8824-Q1 Other Parts Discussed in Thread: DRV8824 Increase the resistance values of these two sensing resistors (to more than 1.2Ω) and lower the output current. Will there be any impact on the stepper motor or DRV8824?
Part Number: DRV8824-Q1 Other Parts Discussed in Thread: DRV8824 Dear sirs,
