References for phase lock loop in STSW-PFCBIDIR
Hello Everyone, I am working on T-type PFC and I refer STSW-PFCBIDIR. May I know the reference for phase lock loop in STSW-PFCBIDIR
STEVAL STWBC86TX programming
Hello, I'm developing a wireless charger based on the STEVAL-STWBC86TX. When designing a new PCB based on the evaluation board, would it be possible to use the I2C converter of the STEVAL-STWBC86TX by removing the jumpers in order to program the new ...
BLDC Motor Control
I am using STGIB30M60TS-L for my BLDC motor control. But when i am turning the motor ON , the current is increasing continuously resulting in overcurrent error. I am unable to find out where the error is present .How to find it out . I am using TSV9...
Resolved! STEL12H24 RBleed Calculation
On the STEL12H24, but am not sure about the calculation for Rbleed:I am designing a 12V system.RBLEED [kΩ] = VIN / 20 – Rb (min)Rb would be about 95Ω (from Figure 14 in the datasheet)That would make Rbleed 12/(20-95) = -160Ω (negative makes no sense)...
Resolved! Component identification
Hello. I need help to identify this ST component. I can see the ST logo top left. Text is like this from what I see:"ST (some marking) G CHG3 648"
Resolved! The pins of STPSC20065WY are oxidized with rust stains and have scratches
Hi Engineer, I purchased the part STPSC20065WY, and I found the pins of STPSC20065WY are oxidized with rust stains and have scratches. Could you suggest whether this is normal, and they are good to use? Thanks a lot, Suri
L9369-tr IC is not responding.
One of our project we are using L9369-tr IC and we are trying to communicate with the IC using TC38X controller with SPI protocol. We are able to send the data but IC is always giving 0x8efffff6 data as a response and it is not valid data. Could yo...
Resolved! BULK ID
Can I find the manufacture year from the bulk ID? Most of ST parts only indicate the last digit of the year, sometimes we just don't know it is 2013 or 2023.
PM8805TR output voltage
Hello everyone I'm working on a student project with an STM35H563RIT6 and a Power over Ethernet (PoE) supply. I'm currently validating my design, but, reading the datasheet of the PM8805TR to do PoE, I just see the output current (max 2A) but no v...
L7987L Failure
Hi, we are using L7987L IC top generate -15V from 24V input. However, we see repetitive failure in the IC. I have attached the waveform also (Green- Input Voltage, Pink- Vout). I am also sharing the layout for the same. Switching frequency we have ke...
