EVAL-L9963E-MCU GUI: balancing not working on 4-cell battery
Hi, i made up a set up of 4 cells and I connected them to the connector of eval-l9963e-mcu. I already changed 4 cells, cause it seems like there is a dissipation for the cells. When I active the balance by GUI i don't see that the cells are balancing...
STUSB4700 - with data
Our application requires charging a laptop at 65W via USBC with USB data passthrough to the laptop as well. A tablet computer is typically used to communicate with the laptop while it is charging. The roles would be aligned with the laptop acting a...
STEVAL STWBC86TX programming
Hello, I would like to program a board with the initial configuration of the STEVAL STWBC86TX. To do this, I need two files: PATCH and CONFIG. Where can I download these files to the STSW-WPSTUDIO GUI of the test board we have?
USB PD and Data transmission from two DFP ports to one UFP
I want to design a USB4 Hub where one UFP USB C port has data connection and charging capabilities for a DFP, but can also get charge from a STUSB4710 that I'll supply with a DC voltage externally. So my hub would have a DC input and a USB C data I/O...
L7805 regulator decoupling capacitro faulier
Hi Sir/Madam, My application is photoelectric sensor object detection or object sensing. I am using the L7805 ST make. Positive voltage regulators output voltage is 5V, and I am giving the input voltage as 24V, and the maximum DC voltage is up to 30V...
STPM34 calibration formulas troubles
Hello! I try calibrate STPM34 device, but have some troubles.I created some xmls file with Reference Manual and AN4470 and compare results by STPM3x_Evaluation_Software and it different. 1) RM use default Vref value as 1.18, but App use 1.22) Calcula...
Resolved! l6566bh based flyback converter ground short together
hi all, i am designing flyback converter based on the l6566bh. i have 2 outputs on the secondary side, both are separate windings (different ground potential) in transformer. can i short together for shared ground reference if isolation is not ne...
Need model simulation for IGBT
Hello ST team,I would like to have SPICE model for STGHU30M65DF2AG and for STGSH80HB65DAG. I've advised to try with eDSim, however I did not find the model in that. BR,Siva
Resolved! Is it possible to use multiple L9963E with daisy chain without L9963T?
I'm using a single L9963E and it works fine. However, I couldn't start daisy chain connection. When I consider BMS architectures in datasheet, all of them has L9963T transceiver to communicate with further IC. My custom PCB doesn't provide L9963T. So...
PWM current LED PCB with STCS2A
Dear all, I received a LED PCB with 16 STCS2A constant current LED drivers in parallel, each powering 4 LEDs. Vcc=12V, for the PWM signal a 5V signal is used, which is supplied as follows: 24V PWM output of PLC is coupled to an optocoupler which is c...
