Resolved! Problems connecting to STEVAL-WPC86TX with STSW-WPSTUDIO
Following on from Solved: Cannot connect STWBC86 to WPSTUDIO V1.8.4 - STMicroelectronics CommunityI am still getting the "Unable to find an [TX]WBC86 device"' message when' I try to connect.Originally the log file just showed the 'Failure to load DLL...
STUSB4710 with a buck boost converter?
The datasheet (and eval board) for the STUSB4710 show the device paired to a buck converter using a >22V supply for this USB C power source IC. I would like to drive the 4710 with 14V (automotive application) and be able to still get the full range o...
Resolved! Why STSVAL-L99615C- can_not_connec to_GUI?
dear ST: Why STSVAL-L99615C- can_not_connec to_GUI?I can use tera toem connect to ST, But could not connect to GUI ?I attached a ppt to descript this situation;My email: 51296211@qq.com
Resolved! STEVAL-L99615C Software GUI: lack of Voltage Acquisition Init - 5Cell + VB + NTC.csv
Dear ST: When I download STEVAL-L99615C Software GUI, en.en.stsw-l9915c.zip,L9961_Script.7z Only contain one file: Current acquisition init.csvanother important file is missing: Voltage Acquisition Init - 5Cell + VB + NTC.csv ? could you fix this p...
TSC2020 - reference voltage
Hi,I can't find information in datasheet of TSC2020 how to connect reference voltage.https://www.st.com/en/amplifiers-and-comparators/tsc2020.htmlIn the componnet are two REF pin. This pins are shorted together or I can use two precise resistors to a...
Resolved! STPM32+XZM-CT50A01
I'm trying to use STPM32 with XZM-CT50A01, and the series resistor = 6.2 ohm. I thought ks = Rb/N = 6.2/1000. But I cannot measure the expected current.The load was 50mA but STPM32 respond 1.2A.The software may be OK because we have confirmed with EV...
Buck coverter with viper115XS
Hello,I'm developing a buck converter exactly like the schematic below. The only difference is the STTHL06 (D2) diode in the feedback loop. In my case, I'm using an ES1J diode, which has a 35ns recovery time. My problem is the output voltage, which s...
IPS160H diag pin impedance
Hi ST-Communitydoes anyone know what the off-impedance of the DIAG pin is when the chip is not powered or UVLO? There is a grey resistor to GND in the "Figure 1. Block diagram" with no description. The datasheet also states a max. leakage current in ...
SPV1050 Battery charging in case of loading
Hello there, I am planning to design an environmental IoT sensor node and i would like to incorporate the SPV1050 IC since it covers my project needs. I did extensive reading of the datasheet and there are some things I would like to get cleared:1. d...
L6699 incorrect startup
Hello, I have an issue with the L6699. The controller initiates the start-up sequence but after a few pulses it stops permanently.I describe the application first:Vin=385VVout=39 to 60 VTransformer magnetization inductance Lm=127uHResonant tank induc...
