Hello,Is there already a solution available to use the STWLC98 or the STWLC38 in TX mode? Is there any application note or some other more detailed description for the TX mode? My problem is the following:I want to transmit 15W, but the STWBC86 can o...
Hi,I have a array of 2x5 STWBC86 on a aluminium plate to make a charging station for multiple devices. They are all connected to a common 5V source and decoupled by a small filter of Ferrite bead and MLCC.After testing them for a while i let them res...
Hi, I am a bit confused about PWM motor driving. Is Vref the same value as Vavg of PWM? I tried to calculate the value of PWM current control but there have the result is not the same current value as I measured from a test, here are the parameters;R...
Hi I have been using the NUCLEO-LPM01A board to measure current on my product, but I require to read up to 180ma . I have had a look at the STLINK-V3PWR unit, and can someone please let me know if I can simply use this wil the cube monitor power pr...
We require a TVS or zener diode for a clamping application with high average power dissipation. LDP01-56AY does suit our needs, but the maximum average power rating is not described in the datasheet. Our application has an ambient of around 60 degree...
Hello, I'm trying to use the SPV1040T MPPT IC to boost up the 1.5V I'm getting from the Solar Panel to 3.8V. When I Power ON the MPPT IC its output just follows the Input and i don't see any chances of voltage getting boosted up. Is there anything wr...
Hi Can anyone id this st device please...Its from a porsche cayenne bms module...vehicle been in a crash and this has blown.... I have id from the another identical item on the board...st-6-6bky z916... This ive found is coming back as thishttps://ww...
Hi,Now I work with the STEVAL-L99615C board and have some problem with it. I don't have an 5-cell board, so I connect charger and all needed saignals directly to the board. The board is configured to work in HS. GUI demo version 2.0.0. Emb. version ...
hi, I'm developing 48v 1kw.Is it possible to set the rising time within 50 ms using l6599ad?The datasheet uses Rss and RFmin to control the initial soft start, but it does not decrease to 400 to 500 ms at all. If you need a circuit diagram, I'll send...
HelloSince the VN920D-B5 chip is not available, I am looking for a replacement. I am looking for another system with similar parameters.Please help me.
