L9963 Eval schematics

Hi, Where can I find the L9963-Eval schematics in Altium format ? Thanks

Why motor vibration in zero speed? i'm using G431B board T-MOTOR 2312 and hall sensor(120 degree), set to torque mode, the motor work fine most time, but it will be vibration when start-up with heavy load or i stop the motor with my hand.

Hi guys,How can i solve the problem that motor vibration in zero speed? i'm using G431B board T-MOTOR 2312 and hall sensor(120 degree), set to torque mode, the motor work fine most time, but it will be vibration when start-up with heavy load or i sto...

Where can I find the SPICE models of STY145N65M5 and STY139N65M5 ?

Hi, I cannot find where to download the SPICE models of STY145N65M5 and STY139N65M5. I can find the SPICE page here:(https://www.st.com/content/st_com/en/search.html#q=spice-t=resources-page=6) But the links above direct me to "SORRY, PAGE NOT FOUND"...

For POWERSTEP01 : while using STEPCLK/DIR mode as well as internal motion engine mode I would like to know

Is there any speed limit or acceleration enforced in step/dir mode? 60min/s*1.67MHz/200st/128uSt = 3260RPM max speed theoretical. What about acceleration in this case?What is the thermal resistance junction to air with minimal copper footprint?What i...
