Hello ST Community,I am currently developing a product using the PM8805 chip and have purchased and tested the STEVAL-POE001V1 evaluation board. Based on the reference design provided by ST, I created my own circuit diagram and manufactured a custom ...
I'm working on developing product, for that I was going through the documents of AC/DC & DC/DC products for reference but, I'm not able to find any detailed documents. If you have any application notes or design documents regarding these products, it...
Hi Sir, Does the STUSB1602 support Alternate Mode? Is an MCU required to enable it, or can it be implemented directly with the MCU alone? Is there any example code available? Thank you.
Hi the datasheet does not contain the thermal junction temperatures for the VFQFPN48, hence hard to work out the max thermal temps for the device. please can you supplyregardsRoss
Dear All,I have created a new schematic for a project I am working on, using the POE Dual Active Bridge PM8805.I have used the reference designs from the datasheet, as well as cross referencing other POE designs online.If someone has the time, I woul...
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...
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...
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...
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...
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...
