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...
Resolved! Transformer Design in AN2794 for Push-Pull Converter
Hello,I’m designing a 1 kW converter using a push-pull topology with 24 V input and 400 V output. While doing so, I referred to the transformer design guidelines in your document AN2794. Unfortunately, I believe there are some inconsistencies or erro...
Resolved! Looking for Complete reference application / schematic of STWBC86 Wireless transmitters
Hi I plan on using STWBC86 for a wireless charger prototype. I was looking at the datasheet for the reference designs and found that the reference schematics has missing or has hard to read values, labels, and wires. Is there a better version of the ...
Resolved! Pin Layout Difference and Equivalent IPM for STGIB8CH60TS-E
We are currently evaluating two ST IPM modules for our motor drive applications — STGIB8CH60TS-E and STGIB15CH60TS-L. Upon reviewing both datasheets, we noticed that although the two devices share the same functional pin descriptions where (STGIB8CH6...
Resolved! PLECS Model of stgwa50ih65
Hello- I am working on simulating a resonant converter based on stgwa50ih65. Can you please share its PLECS model? I am unable to find it on its website. Thanks!
Resolved! STUSB4500 Debug Accessory Mode
Hello,We are currently developing a couple of devices with USB-C DAM support and have chosen to use the STUSB4500 as the power sink on the device side.We would like to understand whether the following behavior is expected, and if there are any optio...
