Hello everyone,I have an issue with my STEVAL-WBC86TX board: recently I loaded a config.file in which I disabled the FHOP.When I connect the STEVAL to my PC using a USB-C cable, WPSTUDIO (both version 1.8.4 and 2.2.5) fails to recognize the WBC86TX d...
Hello,I have a problem to configure the powerstep01. The motor current drops at medium speeds.Current modestep clock mode1/16 microstep48 VoltI have set a low acceleration for testing. Everything is fine up to approx. 16 kHz (microstep). That's only ...
For bta-16, 26-80bwrg orders, the producing countries are Malaysia and China.Is there a quality difference?Is the Chinese product a copy?How can I tell them apart?
I am using a L6470 and everything is working fine with one exception. When I do the initialization of the step mode and configuration registers, if the SW input is low, then the initialization does not work. If the SW input is high, then everything w...
I was picking a 5V high-performance LDO for RF mixer, and found that the parameters of LDL212 are very similar to those of the LDL1117 two series, the specific models are LDL212PU50R and LDL1117S50R, I checked their PSRR and output noise is almost th...
Dear Community,I'm a repair technician and I trying to identify a damaged component made by STMicroelectronics.Based on the surronding components and circuitry its a PMIC/DC-DC Coverter but I cannot find this specifc one.As you can see, all the infor...
In EVAL-L9963E-MCU evaluation board manual,the term 'VTREG' is refered to on many pages in word.But schematic diagrams or figures don't use 'VTREG' like the image attached below.What's the VTREG?
Triac snubberless (bta-16-800bw) does not require a snubber in the circuit?Or would installing a snubber in the circuit have a good effect?The difference between BTA16-800BW and CW is the gate current difference.Will the current specification selecti...
We are currently using the ST1PS02BQTR for powering a compact main board with BT connectivity (STM32WB5MMG), an IMU, and other ancillary blocks (LEDs, charge pump for LEDs, passives). The system is powered through two AAA batteries connected in serie...
Hello everyone, to simulate wireless charging of a smartphone (I want to achieve 5W transmission to the load), I need to use an electronic load and add the load step by step. Since the wireless charging system cannot immediately absorb high current, ...
