STLD41 PWN IN pin not used

Posted on July 26, 2017 at 10:57If I don't need to dim the LED current, what is the correct usage of the PWM pin of STLD41?Thank you

How do I determine a value for Ke for the stepper motor I am using?

I'm experimenting with the EVAL6470H dev board and the Spin Family software. I can get the values for motor inductance and motor winding resistance for the motor I want to use but I cannot find a spec for the Ke value.Can anyone help me understand h...

L6472 Stepper Driver - Does the max/min speed register value conform to the selected step mode or is it always in terms of whole steps?

I am driving a 200 step per revolution motor. The position register per the data sheet conforms to the selected step mode so 1/16 micro stepping results in 3200 steps per revolution. I would expect that the max/min speed registers would conform to ...

If there document describing Motor Control Protocol?

Hello,We are developing product based on P-NUCLEO-IHM002. We understand motor is controlled via serial port. we wondering if there is document describing "Motor Control Protocol" , which allow us to develop custom application.Thank you,andrew

Hi I would like to ask a question regarding the L6924U IC. The SD Pin can I leave that pin Fixed to ground as this will only truly run when power is applied on the Vin.

Hi I would like to ask a question regarding the L6924U IC. The SD Pin can I leave that pin Fixed to ground as this will only truly run when power is applied on the Vin.I have a Li Battery that has a NTC that is rated at 10kohm +/-5% that stops the ba...

Why does the current limit not working in DC-DC converter

Dear All,I am using L6902 (switching buck regulator with adjustable current limit) in my application. The Current sense resistors are used on high side (between supply and load terminal). The current sense resistor value is 0.165 ohm. Thus maximum cu...

i would like to build my own application with out using ST-spin motor library, can any one tell me what is the header file for spin32f0 & programming manual for register configuration details

L6207Q Vref maximum level

Hi all,I have a question about the full bridge driver L6207Q.About the VREF signal, in my design I am going to drive it with a DAC with maximum output voltage above 1V. I would avoid to insert an attenuation stage between DAC output and L6507Q VREF i...

STEVAL-SPIN3201 CAD files or Drawing

Hi,I have looked around for a drawing or CAD file of this evaluation board, someone who knows where it can be found? All I can find is the gerber files.Kind regards Jonatan

L6227Q, Non-dissipative over current protection, how to implement.

In the manual for the L6227Q, Section 4.6 (page 16) it talks about Non-dissipative over current protection. It says the external current sense resistor can be eliminated, I assume I should replace the sensing resistors with a short, but I tried that ...
