STUSB4700 application without I2C conifuration
What happens if I use STUSB4700 in my application but I do not communicate with the STUSB4700 over I2C? Will the STUSB4700 negotiate a contract as a source with the sinking device and offer the PS FB voltages which are connected to the GPIO? I would ...
Evlone 140W PD 3.1 Module Communication
Hi ST Team, We are using EVLONE140W Module to evaluate AVS feature in PD3.1. We understood that this module is also be controlled externally. Please find the attached. I could not get much information her. https://www.st.com/en/evaluation-tools/evlo...

Stand-by of STGAP2HD
Hello.I would like to ask about the procedure to exit the stand-by mode of STGAP2HD. It seems that the procedure described in the datasheet does not work.We can enter the stand-by by setting INA, INB, and BRAKE high while keeping the SD low for 1,5 m...
PD57006TR-E date code
Hi!Can someone please confirm the date code:Trace code as shown on label is 9995120YPart marking label: 9920Y 951 Is the date code 951 which means 2009 ww 51? Datasheet shows this device was released 2006, and EOL on 2018.
Resolved! the information about VN808CM-E's output current
您好，實驗室有用到您們生產的VN808CM_E產品，關於產品規格表的電流-峰值輸出有疑問(圖一)， 0.7A是指八個通道總共的最大電流嗎? 然後我看這個產品每個通道的output一共有兩個是互相連接的(圖二)，這樣會導致輸出的電流變更小嗎?(700mA / 8 / 2= 43..mA (每一個output的電流)) ，如果我打算在output連接端用電流去驅動的話，把同一個channel裡面兩個內部連接的output在外部利用PCB走線，再度連接成真正一個輸出端口的話，可以有助於電流的提升嗎?...
dynamic resistance of TVS
Dear Sirs, Could you advise me dynamic resistance(Rd) of TVS such as SM6T33CAY used to clamp against pulse 5B per ISO 7637-2 or load dump B in ISO 16750-2. Its voltage source waveform is clamped instead of exponential surge curve. Thanks John
By pass capacitor, stability and possible OSCILLATION
STNS01 data sheet dated 14-Dec-2017, Revision 4, schematic is enclosed. What precaution are recommented to prevent the chip going into oscillation. On value of Cap, pcb trace length, rated voltage (MLCC capacitance drops when DC is a good percentage ...
PCB copper thickness
Dear Support, in the data sheet of LED2001, it provided the layout reference, but it didn't mention the copper thickness. for the demo board, what is the copper thickness in oz of the PCB of.STEVAL-ILL054V1, Thank you very much, David
Resolved! Strange response from L6981N50DR. (L6981)
Hi, In one of my designs, I used the L6981 5.0v low-noise variant. I followed the datasheet, and this was my first time using this chip. However, I added an option that separates the AGND and PGND pins with a ferrite bead which is not present in the ...
