Dear community,Scope of the work: I'm trying to measure the back EMF of a stepper motor. I'm following the ST application note AN3327, which suggests that the back EMF is measured as the residual voltage on the coil when i_coil = 0. Problem: when mea...
Hi, starting from the documentation :"The UVLO, TH_WRN, TH_SD, OCD, NOTPERF_CMD and WRONG_CMD flags are latched: when the respective conditions make them active (low or high), they remain in that state until a GetStatus command is sent to the IC. "My...
Please see the attached picture. Our company is using L6470H chip for our design. According to the typical application in the datasheet, we want get 3V on the ADCIN pin. Our Vs is 24V and the voltage divider resistors that we chose are Ra= 13K and Rb...
I have downloaded and installed the SPINFamily setup msi file. The User Manual UM2022 page A.3 describes programming the nucleo board with the firmware file guifw-STM32XXXXX-nucleo.binI have not been able to locate this file for the F401RE Nucleo boa...
I have downloaded a copy of the en.x-cube-spn5 but I am unsure how to add this to the STM32CUBEIDE to allow me to run the example programs. I would then like to develop new applications using a pair of X-NUCLEO-IHM05A1 boards and a Nucleo-F401RE boar...
Hello. I have a custom made board with an L6390 used to drive two MOSFETs. My switching frequency is 100kHz. I noticed that at low duty cycles the bootstrap capacitor was not charging correctly. Per the datasheet, I discovered that due to the interna...
I designed PCB with STSPIN32F0 and my MOSFETs sometimes breaks down. I think because of break-in. I started to look at oscillograms and i was surprised. Then I took the STEVAL-SPIN3201 and repeated research. It's the same. I explored waveforms for ga...
The RHFL4913A data-sheet (Figures 4 and 5) show a 47nF capacitor between Vo and Adj pins. How critical is the value of the capacitance used here and what is the affect of changing the value?For example, if I only have a 15nF or 100nF ceramic capacit...
I have two questions about the STSPIN250:What is the overcurrent threshold? It's not listed anywhere in the datasheetAfter what interval is the overcurrent threshold triggered? The datasheet mentiones a Toff time, but that's for the PWM current contr...
