Part Number: DRV10975 Hello,
I've been working with the DRV10975 Z in attempts to drive a Maxon 351056 . I have followed the quick start guide using i2c to manually write and read registers and speed with a Raspberry Pi Pico. It seems as though I can…
Part Number: DRV10975 Hi team,
Do I need to use an additional MCU to control the DRV10975?
I just want to apply it to the fan drive. And can use PWM to control the speed externally. Similar to A5931
Part Number: DRV10975 Hello every one,
I am currently working on a BLDC motor control project. I use chip DRV10975PWPR
My MCU is ESP32
Now I can I2C communicate with DRV10975, write and read into register successfully.
The configuration parameters for…
Toshiro-san,
Toshiro Imi said: 1) the way to improve seamless and quick transition from open loop to closed loop
Quick transition from open to closed loop can be achieved by minimizing the align time, increasing open loop acceleration constants A1, A2…
Hello Mitja,
Once the device receives the command the start-up timing is mainly dependent on the align time or IPD (which is disabled in this case). Here is a chart from the datasheet for reference.
Also make sure your algorithm is not delaying sending…
Part Number: DRV10975 Hello, why I can not change speed of motor with speed pin. I have tried using PWM and potentiometer. With PWM no mather what it is always 100%. With potentiometer it will not even turn on until when it is half turned, then it will…

NOT driving the Motor when EEPROM operations are attempted.
As the project is a medial application, customer wants to write EEPROM every power up to assure the configure right.
Background:
Customer had used DRV10975 with the same way (write…
Part Number: DRV10975 Other Parts Discussed in Thread: DRV10983 , Hello,
I am having throuble with reading and writing registers with ESP32 and I was wondering can I connect my chip to GUI with CH341. Thank you for help, Mitja
Part Number: DRV10975 Hello,
Our customer asked about motor speed control by taking Analog Input mode on SPEED.
While he tries to change motor speed by adjusting SPEED input by analog mode, are there any restriction or limitation there, such as speed…
Part Number: DRV10975 Other Parts Discussed in Thread: DRV10987 , Hi:
I can used the DRV10975EVB to control the motor speed by IIC .But it do not work in my appylication.
Following is my soft initialization:
1. 0X03 write 0X40 (enable EEPROM config)
