ST1S40 Max Current Problem On Different DC Sources

I made an DC-DC buck with ST1S40 in the simulations my output current is normal max 3A but in PCB i cant Load with 3A while using Chroma 6703.When i use my normal DC power supply i can Load with 3A and its not collapsing.I use GWINSTEK PEL-3041 Elect...

L99DZ100GTR labels & Top markings

Dear Support,For this part, there are 2 labels of 2022 D/C, and 2 different marking. are these two original labels are valid? Why are there two different labels? 

Driving LED1 signal on STPM32(electric meter ic) by STM32F1x

Hi guys,I connected STPM32 evaluation board (UART mode) to STM32F103 board. I use of stpm32 firmware from st.com. and it work. I can measure and read rms voltage, rms current, active energy and.... . but when i set pulse/kwh LED on stpm32, I have be...

Reading from STPM32 ic by STM32F103. is it an Error?

Hi Guys,I use STM32F103 with STPM32(single phase electric meter ic) evaluation board. i used of stpm002 firmware to connect with stpm32 and read measured data from it. like RMS voltage and.....  I want activate LED1(It connected to pin 4 of STPM32) ,...

I would like to request the LTspice model for the following parts. ADP480120W3 SCTHS250N120G3AG

Please check the label and let me know if the parts are original and belongs to STM

L99H01 Motor driver has programmable cross current protection for H-bridge. My question is how can i know if cross current occurs? there is no register bit for this fault and also the fault pin

Hi, Do you have a spice model of STN3P10F6 PMOS transistor? Regards, Sébastien

Control mechanism of VB_SW pin of L9396 component.

Hello,The component in question is L9396. I have a question about the properties of the 'Protected battery switch' pin (VB_SW) of this component. In the datasheet for this pin, both 'The device provides a fully protected switched battery output VB_SW...
