I built STUSB4710AQTR design basing in evaluation board. I connected it to Microsoft Surface Go tablet which support USB 3.1 PD . However I don't see any negotiation through CC lane: only tablet send 16Hz .Please advice what can be problem and how to...
Hi,I am using STUSB4710AQTR. I build my board basing on reference design. Now I connected it to Microsoft Surface Go tablet. According datasheet this tablet support USB3.1 PD. However I even don't see any negotiation through CC lanes: only tablet sen...
I have an ac dc converter project based on flyback (85-270AC / 12V_1.5A-15V_0.125mA) and at the output I do not have voltage regulated. The project was prepared with the help of e-Design.I was able to operate when I pressed the tip of the oscilloscop...
please help me to under stand calculation of bldc motor ramp up in open loop
I'm running the motor in torque mode with an encoder. It works really well.The only problem I have is that something internal to the FOC software adjusts the torque down at (very) low and zero speed. I assume this is done to avoid the motor overheati...
I attended the excellent motor control sessions last week at the ST Developers Conference in Santa Clara, CA. At the presentation I received the Nucleo F302R8 and X-Nucleo-IHM07M1 boards which I've been experimenting with. However, I would now like...
Posted on September 22, 2017 at 11:45Hi,Does anybody has experience with the evaluation board IPFC01V1 for the PFC-Controller STNRGPF01?My Problem is that the board crashed at a experiment with no load connected to it.Does anybody have an Idea what ...
Hi, I'm using the powestep IC to control a stepper motor. All is going well but I can't figure out how to move the motor from one point to another at specific speed. e.g. if I send the goto command, like goto(1000) the motor do Accel--->max_speed-->D...
Anyone knows what's happening with the productoion of the voltage regulator LD39300PT-R? I am trying to buy this component for weeks and all distributors have no stock of this part number. The factory delivery time, in every distributors is 50 weeks!...
Hi,There is a datasheet on digikey page related to LDL212 product wihch shows pin1 is Output Voltage but the datasheet on ST website shows pin1 is Ground.I beleive there is a mistake on datasheet on digikey page.A picture is attached thanks.
