Hello everyone,I’m having an issue reading the current sense (CS) output from a VND7040 using an STM32G473 ADC.When driving a DC motor with PWM:• At ~50% duty cycle, I measure around 500 mV on the CS signal (after RC filter) using an oscilloscope• At...
Hi, I'm checking the flammability specifications for MJD31CT4. I need to know if the molding material of this part is rated UL94 V-0. If it's not V-0, could you tell me what the official rating is? Any link to a supporting document would be much appr...
We are students that are trying to make a multi frequency power system interconnection model with a dc link similar to real life back to back hvdc, and we need a converter that supports bidirectional power transfer, is it possible for STEVAL-IPM15B t...
Hello everybody,I'm using an L6981C50DR for supplying a small board with 5V. The schematics is attached and should be perfectly conform to what is described in the specification from https://www.st.com/resource/en/datasheet/l6981.pdf as "Figure 4. Ba...
Hello everyone, I am currently working on a lifetime estimation for a SiC-based power converter design. I am specifically looking for Power Cycling Capability data for discrete SiC MOSFETs in TO-247 packages. While power modules (like HybridPACK or E...
We would like to get spice model of STD10NF10T4 to do some simulation. Who can help me on this? Thanks. BRADeng
Using the NVM configuration utility for the STEVAL-ISC004V1 seems to program fineHowever regardless of what I am writing the to the NVM, the source capabilities on the device dashboard never change and always show 3 PDOs for 5, 9, and 15 volts.
Hi,I would like to use the evaluation board STEVAL-IME014V1B to drive piezoelectric transducers for medical applications. Does the evaluation module include a built-in H-bridge for direct drive of ultrasound transducers? May I directly connect the de...
I can't find the Datasheet of this component, any help?
We currently use the WLC38, but wish to use the WLC89. Our sales provided the full datasheet, and is ordering samples of the STWL89 for us. However, there are no more evaluation kits available.Can the eval board reference design files and/or gerber f...
