Is there any reference code for rotation certain angle with DRV8846 & stepping actuator ?
As I know, the process of rotation certain angle has three steps: slow down , acceleration …
Part Number: DRV8846 Hi Team,
in the evaluation of DRV8846, I have following questions about DRV8846 so could you help? I also summarized more detail in attachment so please refer it.

Part Number: DRV8846 Dear team,
When customer change VM from 5V to 12V, the motor could not rolling. The specific operation as below:
1. VM 5V, current 1.3A peak, and frequency about 1.2KHz;
2. VM 5.7V, current 1.7A peak, and frequency max about 1KHz;…
Part Number: DRV8846 Hi
Could you please let me know the Max and Min value for the following Pulldown/up resistors?
My customer need those value for their IO design.
Thanks

Part Number: DRV8846 Dear team,
Customer met an issue that when DRV8846 was initially powered on, configuration programed, the motor works normal. Then if they cut off the power then power on again, the motor did not rotate any more.
They asked:
1. If…
Part Number: DRV8846 Dear all,
For the sensing resistor of AISEN and BISEN of DRV8846, how to determine its value and power consumption?
Customer want to choose the right resistor to use including the value and size.
Thanks.
Part Number: DRV8846 I have a couple of questions.
1) What's the input impedance of the VREF analog input? I'd like to make sure VREF can be set from an external DAC with somewhat limited current capability. The specsheet says that VREF input current…

Hi team,
Customer want to use DRV8846 to achieve dynamic torque(force) control, so they need to use a DAC to drive the DRV8846 VREF pin. This is workable, correct?
Based on this, could you suggest what signal frequency is recommended…
Part Number: DRV8846 Other Parts Discussed in Thread: DRV8847 , DRV8412 , DRV8844 Hello,
We try to control 2 DRV8846 with 1 set of GPIOs, i.e. we'd like to share tri-state pins between the two DRVs.
We would want to know if there's any potential issue…
Part Number: DRV8846
Hi
My customer would like to check the Rpd max and min value of DRV8846. The datasheet only shows the typical value of this parameter.
Thanks!
