Hi all,I connected my SPV1050 chip as you can see in the picture and started to measure my circuit. It looks pretty good. I powered it up with 3.3V at IN_LV. And I can measure a voltage of about 2.416V at the STORE pin. And even the LDO2_EN pin got a...
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 ...
Hello i have problem with evaluation kit. I tried to connect evaluation kit to battery pack model that was made from 13x parallel combination of capacitor 470nF and resistor 1kOhm. I wanted to measure voltage on seperated parallel combinations repre...
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...
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?...
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...
Dear STM, May I know do you have product roadmap for Qi2.0 compliant 15W RX, due to obsolescent of Qi1.3 on 2026.
for LED2001, the marking on the chip like LED2K1xxxx118. or xxx125. how to understand the Marking under the LED2K1? Thank you,David
Hi All,As mentioned in the datasheet for part the part STPS10200SF, it was stated that cooling will be conduction cooled.Please clarify that the cooling method will be either top cooled or bottom cooled.Thanks in advance.,Ganapathy Raman.I
Hi all,I am designing the custom wireless charging receiver using the STWLC38JRM chipCurrently, when I put the circuit on the wireless charging pad (Qi standard), I notice that the STWLC38JRM chip does not output 5V at the VOUT pin. Below is the sche...
