Oscillation on back EMF measurement using the STSPIN820 and a stepper motor
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...
Resolved! L6474 : behaviour of status register
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...
Resolved! The leakage current of L6470H's ADCIN pin
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...
Resolved! Unable to update Nucleo board firmware and to connect the SpinFamily evaluation tool to the Nucleo board
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...
Resolved! How can I incorporate X-CUBE-SPN5 into STFM32CUBEIDE
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...
Resolved! External diode in L6390 for high switching frequency
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...
STEVAL-SPIN3201. Incorrect signal waveforms to drive N-channel power MOSFETs
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...
RHFL4913A requirements on capacitance value between Vo and Adj pins?
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...
Resolved! STSPIN250 overcurrent
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...
