Part Number: DRV8889-Q1 Hello team.
Please tell me how to determine the torque count value specifically.
I understand from the data sheet that the torque count value is determined from the difference between the back electromotive force under load and under…
Part Number: DRV8889-Q1 Hi,
The following waveform is measured, yellow is PWM, green is current; we use micro-step drive, the peak current is 160mA,
So how do I calculate the current error output by DRV8889? Is there any formula you can provide me with…

Part Number: DRV8889-Q1 Hi Team,
Recently, 2 pieces of DRV8889 chips have been found to be damaged, 1 piece is PIN13 damaged, and the other piece is PIN6/PIN7/PIN8/PIN9 which is a low level and cannot be pulled up. In order to improve EMC performance…
Part Number: DRV8889-Q1 Hello team,
Greeting for the day.
Our customer encountered some EMC problem in the lighting application. They found that the over-limit near the 80M frequency was strongly correlated with the working state of the DRV8889, when force…
Part Number: DRV8889-Q1 Hi team,
My customer have question about step/angle initialize conditions.
In my understanding, step/angle initialize when after power-up, after exiting logic undervoltage lockout, or after exiting sleep mode.
If these are correct…

Hi Chase,
DRV8889-Q1 supports a wide variety of SPI frequencies. Please refer to Table 6.6 on page 9 of the DRV8889-Q1 datasheet for minimum timings on each of the signals. You can refer to this diagram from DRV8462 for description of various parameters…
Part Number: DRV8889-Q1 Hi,
Currently using DRV8889 and need to verify the SPI timing design function. It is necessary to ensure that t(READY), t(HI_nSCS), tdis(nSCS) are within the specifications. Do you have any suggestion how to conduct this test?
Thanks…
