Resolved! LD1086DT33TR and ESR
I plan to use the LD1086DT33TR LDO to output 3.3V with an input voltage of 5V. However, I am not aware of the requirements for the ESR (Equivalent Series Resistance) of the output filter capacitor for the LD1086DT33TR, and this parameter is not menti...
EVAL-L9963E not working
I am testing the board with a 14s Li-ion battery, but I am unable to read the cell voltages or configure any register through the GUI. I shorted the X1 and P2 power supply inputs and supplied 12 V to both. This was the only setup in which I could g...
Output current of each channel and pull up for open load detection (VNQ7E100AJ)
Hi, I'm working with this VNQ7E100AJTR IC , I have a connected the solenoid of rating 2.2A rating at one output channel. the particular output pin got damaged and irrespective of the input the particular output pin is always High (12V). what is the m...
STSPIN958 H-Bridge, current measurement in II and IV quadrant?
We have a prototype board with the STSPIN958 full bridge but we see that it cannot measure positive current (in coil) when the voltage is switched negative, output shows current = 0.We switch from 48V to -48V on the coil. (turning the magnetic field ...
STSPIN948 and stepper motor
Hi,does anyone in the world have used a STSPIN948 with a stepper motor?I'm having many problems, also because of lack of documentation and examples.I need to control a NEMA 23 motor, but if it turns slowly it works, over 2 turn per second it hangs.I ...
Question re: BMS control and Inverter control
Hi,I was hoping someone may be able to point me in the right direction for two projects I am looking to research:1.) BMS - to what extent is there a mature ecosystem and codebase for scalable battery management - not only for varying call capacities,...
Resolved! Stm32 Nucleo 767zi power on issue at 12V Vin.
Hi!I have an issue with stm32 Nucleo F767zi power setup.When I power up the stm32 Nucleo F767zi on 12V, the regulator ic and the controller chip heats up. Why?I have also changed the JP3 jumper to (Vin-5V) option. And the JP1 jumper is off.What's the...
HEMT and the new Powerflat 8x8 devices
After visiting the ST website the new GAN 700V Fet's got my attentionPart numbers starting with with SGT are under evaluation.Tested a few mastergan4, I found those very fast and could reach easy the 3 MHz with low rise and fall times (below 10ns)My ...
Help with vnf1048f efuse
I have been trying to use the EV-VNF1048F with the vnf1048f high side switch on it to act as an SPI slave to an external ATSAME54 microcontroller master. I just want to read the current that the efuse experiances when connected between a DC power sup...
