DRV11873: To control the BEMF of DRV11873

Part Number: DRV11873
Other Parts Discussed in Thread: DRV10970

Hi team,

I got a question from customer.

"I am researching BLDC motor through your DRV11873.
In order to operate the BLDC motor at low speed using DRV11873, the PWM signal is being transmitted to DRV11873 using STM32. When the motor is operated in that way, when the PWM signal is transmitted, the motor initially rotates at high speed and then at a speed that corresponds to the PWM signal. Referring to the data sheet, I think we can rotate from the beginning at a speed that fits the PWM signal by analyzing the BEMF in some way, but I am leaving an inquiry because I want to ask for a detailed explanation.
Also, the current minimum speed is about 120 RPM, and I would like to know if I can rotate the motor at a lower RPM."

Thank you very much for your help.

Best regards,
