Resolved! Common mode filter assistance for the PM8805
Hi All,To start, I'm a hobbyist and although I am OK with digital, analogue and the maths surrounding design is beyond me. I am seeking assistance in specifying the values and component suggestions for the CM Filter as noted in figure 7, page 19 o...
STPM01 IC - Offset Values at Zero Voltage
I have been working, with STPM01 as a peripheral device with my micro controller to develop a e meter. On development with board, on testing on no voltage and no current or in case of voltage ( 220 - 240 AC ) AC and no load current. During these tim...
EVAL-STCH03-45W PCB Design Files & Magnetics Calculations for 24V, 28V, & 48V
Dear STMicroelectronics Technical Support Team,I am writing to request the design files and magnetics calculations for the EVAL-STCH03-45W evaluation board. I am specifically interested in adapting this design for the following input voltage 84-264Va...
AN2761
Hi,We have designed PFC using L6562 referring application note AN2761 on that the auxiliary winding is used only to sense the zero current detect calc. is in Equation 65 but we also need to power the ic using the same winding.Where can i get that cal...
Question about STPM01 not reading 0 at no current. (See details)
Hi!I have a couple of questions regarding the STPM01 energy metering circuit:We are using it for measuring currents only with Rogowski coils. (We have 4 circuits on our board).We are not using the voltage measuring, so it is not connected.The microco...
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...

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...
