Part Number: DRV8889-Q1 I am currently using the DRV8889A-Q1 in my design and have a question regarding the SPI timing specifications.
I would like to know about the required duration for the nSCS pin to remain High. According to the datasheet, there…
Part Number: DRV8889-Q1 Other Parts Discussed in Thread: DRV8452 , DRV8434S Tool/software: Hello everybody,
I want to drive the motor driver at Full Scale Current of 1,5A, so the VREF needs to be 3,3V and TRQ_DAC = 100% (according to formula on page…
Part Number: DRV8889-Q1 Hello I'm using DRV8889. Can I measure the current torque figures coming out of the product?? Does the TRQ count mean that?? If so, I would like to know how to convert this figure into torque.
I'm using the lin communication…
Hi Kosma,
Thank you for reaching out to us.

Part Number: DRV8889-Q1 My part is DRV8889AQPWPRQ1, manual www.ti.com/.../drv8889-q1.pdf,
p52, lists possible values for CTRL8 lower 4 bits as 0, 1, or 2. My chip reads 3, i.e 11b.
So is this wrong ? All rest of CTRLx values seems to checkout to…
Hi Songhao,
Thanks for your post.
Bao Songhao said: SPI is currently set to mode 1, that is, CPOL is 0, CPHA is 1, what is the communication frequency range of SPI?
As per datasheet it can be up to 10 MHz SCLK. Typically applications use 1 or 2…
Part Number: DRV8889-Q1 i'm with DRV8889A-Q1 in my design and i'm considering doing all stepping through SPI.
I saw this old post (linked related thread), where TI mentions errata sheet for the device.
I cannot find any erratas for this chip, was…
Part Number: DRV8889-Q1 Hi team,
Customer is using our DRV8889-Q1 in their lighting product.
The current waveform is shown below:
I noticed that this may happen when under slow decay. But customer is using Smart tune Ripple Control.
Can you…
Part Number: DRV8889-Q1 Tool/software: [Question]
For Open Load detection.
Is it possible that nFAULT pin does not indicate the error(Low) while there is Step signal if Motor is set to Open? Fault is only detected if there is no Step signal?
Part Number: DRV8889-Q1 Tool/software: Hi Murugavel,
The thread "DRV8889-Q1: DRV8889-Q1 stall detection issue" has been locked. Sorry for opening this thread for response.
We got 14HK0407N stepper this week, and the good news is we could detect stall…
