For the RHFL4913A IC, can the NC pins (9,11,12,16) for the flat-16p be attached to ground without affecting the operation? Are these pins internally grounded?

Hi,i would like use the speed mode FW with modbus, it is possible? For to do this i should change the source code or i can put the parameter (rpm) in a specific register?@Enrico Poli

STC3115AIQT: Is there a recommended substitute for this part? The lead time for this IC is quite long at the moment, so we are investigating our options regarding substitutes that don't require firmware changes.

Why is the power efficiency of the SPV1040 not matching the datasheet values?

Hi all,The application that I am building uses a rectenna to provide DC power to anSPV1040 which performs its MPPT algorithm and outputs the converted power to anattached load (VStorage). Here is how the SPV1040 is configured for ourapplication: The ...

Resolved! PowerSTEP01: Electrical constant of the motor (ke): clarification need for ST documentation: "Measure the peak voltage ..": What to measure exactly: Vpeak-to-peak, Vpp/2, Vmax or ... ???

In UM2022, Appendix C Motor electric constant (Ke) measurement written:"Measure the peak to the frequency ratio" (by oscilloscope).Our question: what voltage to measure EXACTLY ?:Vpeak-to-peak, Vmax, Vmid, etc ??I think it's fundamental to get the ri...

In my project one of STM32H7 ADC channels is used to measure the device current. I'm using STOP mode with periodic (10 ms) wakeups to lower the power consumption. Is it possible to use the ADC channel to measure the current during STOP mode?

Resolved! When will some one reply: X-CUBE-MCSDK-FUL request? 6 days and counting. When will there be any B-G431B-ESC1? I found some at Newark but checking on tracking I find they are selling wishes, shows in stock but not shipping....

Hello, what is the difference between the L6599 and the L6599A ? can i replace the L6599A by the L6599 ? (no stock of L6599A) Thanks Regards

SCS serves as a chip select for both Serial and SPI interfaces - When using serial, can you connect multiple STPM32s in parallel, and use SCS to select which device you want to talk to ? The datasheet reads that way, but I wanted to confirm. Thanks

Is it possible to recognize partnumbers or parameters of cores in HB-SAB tranformer? Core material and gap?
