Im developing a custom board with a non ST microcontroller, the board has 6 mosfets and i wish to monitor them using ST's TSC1641 Is it possible to have 6 of the aforementioned sensors to monitor each mosfet? Also is the exposed pad at the center rea...
Hi everyone, I met a problem when I measured the current rms value with stpm33 ic.I'm using this IC with resistive loads and other load profiles with low crest factor. But I met a case with a high crest factor load like as SMPS type loads. I collecte...
I am trying to get 12V at the output of STKNX buck converter, but I am not getting it and the STKNX dead.The RFB1 that I am using is 33K Ohm and the RFB2 is 3k Ohm, with these resistors the Vout would be 1 + 33k/3k = 12V. The maximum value of this vo...
All,I'm working on the basics of getting the SPI communication set up for the L9780 IC and am running into some issues, so I'd appreciate some feedback or a double-check. It appears so far that I'm able to send a command via the control word and succ...
Background:Our project utilized ST's IMU sensor LIS3DH, and according to business requirements, we used click interrupt and initial interrupt respectivelyThe sampling frequency is 10HzWe set the duration of the Initial interrupt to 120 to generate an...
We based our circuit on the "STKNX Reference Design" (V1.0, 14. Nov. 2019)).In the case of the single fault condition of a shorted CFH capacitor during operation almost the whole KNX bus voltage (21-30V) is permanently over the 68R resistor (RTX) and...
Hi,I am working on the LIS2DU12, but unfortunately it does not yet work as I expected. I do a reset and wait with the status bit of reset until it is done. The system is therefore in power-down. I then set the drdy. This immediately triggers the int...
Hello everyone I am looking into the STPM33/34. I only want to use 1 SPI bus for both ICs and select it with the SCS. In the datasheet I cannot see whether the MISO goes into tristate when the IC in question is not active. I also cannot see any infor...
Hi,during maximum heating tests of our device, we measured a case temperature of +92 °C on the STKNX (on top of the plastic package via thermocouple). The environmental temperature near the STKNX and the PCB was +85 °C.On the borderline, but ok in my...
Hello everybody. Currently I'm researching different power metering solutions. STPMC1 is a possible contender for my application, but I wasn't able to find some specific information in the datasheet.These are some things I'm unable to find:1) How oft...
