Hi Sir,
I tried testing DRV8434A-Q1 and compared with DRV8424-Q1.
We can see that VAOUT1 voltage drop has decreased.
The voltage drop of VM and VAOUT1 are still very large.
I tried using 1/32 ustepping but I couldn't confirm if it improved the viltage…
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:

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,
Here are some questions about DRV8824. Please help to input your comments.
Thanks.
1. As layout guide in datasheet, the low ESR ceramic bypass capacitors are recommend. May I know…

Hi Team.
According to the following diagram, to avoid motor saturation, it is recommended that the Ifs current is less than the DC maximum current of the drive circuit. In this case, the corresponding current is the smallest when…
Part Number: DRV8824-Q1 Other Parts Discussed in Thread: DRV8824 Hi all Would you mind if we ask DRV8824? <Question1> How much is the Tdeg time? There is no description on the datasheet. DRV8824 shows 3us typ. Is it the same? <Question2> How much…
Part Number: DRV8824-Q1 Dear, All
Customers are considering DRV8824-Q1. They are required to prepare internal review materials for recruitment and accurate center value of current at full step is required. The setting value at full step is described in…
