Resolved! STSW-WPSTUDIO GUI cannot connect to ST Wireless Charging board
Hello,I purchased a set of Wireless charging evaluation boards (RX & TX) on Mouser.com for $160.The 2 board names are STEVAL-WBC86TX and STEVAL-WLC38RX. I use STSW-WPSTUDIO V1.8.4 software to try to connect to the board from my PC and get access to t...
Resolved! Download STSW-WPSTUDIO
I bought the STEVAL-WLC99RX evaluation board for the STWLC99 Qi 1.3 compatible receiver and cannot find a location to download the GUI to program/monitor the receiver. The page that I am pointed to (https://www.st.com/en/embedded-software/stsw-wpstud...
Low current bypass disable VNF1048
Good morning, We are evaluating the use of the VNF1048. During the test phase the problem arose that despite the MOS being in the open state we detect a current flow, even if minimal, that for our application must be avoided. From our point of view t...
Resolved! [3D Request] Missing information: X-NUCLEO-IHM04A1
Dear STMicroelectronics Team, Good day. This is Louie from SnapMagic Search. We create PCB footprints, schematic symbols, and 3D models for electronic components. One of our customers is looking to integrate X-NUCLEO-IHM04A1 into their design and ha...
Resolved! VLxx voltage limit on STPMIC1DPQR
V SWITCH_MIN (VLXx)is measured below the the absolute maximum rating on datasheet (-0.5V).However this limit is momentary ony (7.2 ns) as shown on the measurement.Usually datasheet specifies the minimum DC limit and minimum limit during transient val...
Wireless Charging - Transmitter
Hello,I am looking at the STEVAL-ISB027V1 dev board. I see that it is obsolete. That is fine, I am more interested in understanding if this design could be implemented on 6x independent channels of Tx coils. I want to be able to independently control...
Resolved! Understanding Max Current Specifications for VNH motor driver family
Hi, I'm trying to spec a fully integrated H-bridge for driving a small motor taking up to 6A nominal, with spikes up to 12A (looking at the VNHD7012AY, VNHD7070AY, and the VNH7100BAS). There are a lot of numbers for current limitation on the ST datas...
STEVAL-A6986IV3 grounding capacitors
Hello, I am strongly considering using the STEVAL-A6986IV3 based design for a 4 channel isolated gate driver power supply. One thing that looked strange in the the schematic was the four ground capacitors Cgnd1,2,3,4 which are 4.7nF 2000V rated. The...
Resolved! Questions about to Auxiliary power supply with VIPER06
HiI have a question about the conection of VIPER06 module as auxiliary power supply. I Have a power stage PFC with L6562 and two capacitor in series as outuput capacitor. Then, i need a 15V aux power supply. Can i connect the VIPER06 Flyback stage,...
Resolved! L6982C33DR & L6982C50DR always provide 2.5V output
Dear Community,I’m currently testing the L6982C33DR and L6982C50DR to supply 3.3V and 5V to my board.I followed the reference design provided in the user manual and completed the PCB layout accordingly.However, when I power the board with 12V (Power+...
