Hi,
I have a question about sensorless BLDC.
In addition to BEMF, it seems that magnetic linkage can also be used to estimate the rotor position, and do we have products…
Hi Venkatadri,
Thank you for your reply.
Not refer to analog HALL sensor. It is a solution without sensor, just like the BEMF method to know the position of rotor. Have you ever heard it before? I give more detailed description in the new thread. You can give…
Part Number: DRV10970 Hi,
Our customer is using DRV10970PWPR parts, and the assembly location for this product is Taiwan.
Could you check if this is affected?
Best regards,
Hi Higa-San,
This shows motor phases and sensors are aligned in this combination.
Can you also check changing FR value and if the motor works properly with this winding connection?
Thanks and Best Regards,

Part Number: DRV10970 Hi, TI expert
I have an inquiry regarding defective incoming goods from a customer with respect to the application of DRV10970.
The review of the defective incoming goods revealed that the current waveform is irregular and exhibits…
Hi Andre Burkard,
Problem 1: I guess, that I can apply up a 3.3V signal to the PWM pin, even if VINT is down, is this correct?
Yes, PWM pin wakes up device. VINT rises when PWM is applied to wake the device from sleep mode.
Problem 2: The power supply…
Part Number: DRV10970
The hardware design was carried out as follows, and I am trying to control the motor speed by applying PWM to the DRV10970 IC, but the control is not working well.
When PWM is applied, the motor responds slightly but does not…
Part Number: DRV10970 Hello When we look at the TIDUBH6 file, it seems that 3 single-output hall sensors are used. However, 6 signals, positive and negative, are input to the driver IC. What is the reason of this? How is it?
