STEVAL-IHM023V3 in "3-phase HV FOC control for SMPMSM". We plan to use external control with 5V digital signals for all inputs (E-stop, PWM-H,L, brake, etc), It is save to set the Vdd at 5V in that case?

We're planning to develop some motor drive academic boards for SMPMSM FOC motors for Master Students and for one of the parts we're using is STEVAL-IHM023V3. We're currently development the platform.In the manual UM1823, page 28, table 6 for FOC cont...

What is the minimum input pulse width for L6391 and L6386 gate driver?

For the ALED1262ZT, the customer wants to know if there is software available. I do see that there is some software with the eval board, but he doesn't want to use that.

I am interested in using the VIPer53-E in a fixed frequency offline non-isolated buck configuration.

I have seen other products similar to this one from other suppliers that can work in this configuration in addition to the flyback topology. Can this part be used in a buck topology?

LT-Spice Model L5973D

Dear Sir or Madam,we use the DC-DC Converter L5973D in some circuits and i want use it in the future, too. To do it easier I prove the circuit with a LT-Spice based programm.Now my problem is, that your offer a encrypted Pspice-Model. It is possible ...

L6470 initialization

Hello,I am trying to control L6470 mounted on IHM02A1. I downloaded the example software (https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/stm32cube-expansion-packages/x-cube-spn2.html#...

Used eDesignSuite to design an isolated AC to DC Flyback converter circuit for wide voltage AC input, and 5V, 0.8A DC output.

The eDesignSuite result and my schematic are attached. A PCB was manufactured as per the eDesignSuite BOM and design guidelines. I connected mains to the circuit without SJ4 being bridged. Rin immediately blew. The design BOM specified a 7.5Ω , 2W re...

STEVAL-SPIN3201 and MATLAB/SIMULINK

Hi,[1] Is this board supported for automatic code generation in MATLAB/SIMULINK ? [2] How high must the electrical rotary field resolution be for FOC operation, if I want to operate the PMSM without an observer? [3] Is it possible to switch the opera...

Would like to use STNRGPF01 Digital Controller for a system with 480 VAC input. The AC input voltage sensing is isolated, is there a reason this can't be used at 480 VAC?

When trying to set up a simulation in E-Design, the highest input voltage that can be input is 265?If this can be used at 480 VAC as I suspect, how do I get the voltage settings on the E-desgn tool revised
