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 ...
L9963E Eval Board GUI Error
Hi There, I want to try the L9963 development board. I downloaded the GUI but I get an error. I go to the site from the warning and upload but my problem persists. Could I be having this problem because my computer is Win10?Does anyone have a solutio...
LED2001 Smoked with set to 4A output
Dear Support,I have a design which works fine even drive it full PWM with 0.025 ohm (4A max current). we need to control the backflow current so added a diode on the power supply path. the schematic is attached. C169 and C170 not installed. it works...
Resolved! Wireless Charge IC Qi2.0 Products
Dear STM, May I know do you have product roadmap for Qi2.0 compliant 15W RX, due to obsolescent of Qi1.3 on 2026.
Marking on LED2001
for LED2001, the marking on the chip like LED2K1xxxx118. or xxx125. how to understand the Marking under the LED2K1? Thank you,David
