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

Resolved! Where can I find a document that details how the STBB1-A components are marked?

I looked through the datasheet looking for a section that details what markings I can expect to see on an STBB1-A regulator IC, but I couldn't find anything. I imagine it will just be an abbreviation and a date code and/or factory location, but I'd l...

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...

Thinking of using the new VIPERGAN50TR. I've looked at the EVAL power supply for 5, to 20 volt output. Is there any applications for 90-164VAC input and 150 to 250 VDC (adjustable) output with small output current - say 100 to 200 ma?

STWLC68 OTP Programming in a automated production environment.

We've designed the STWLC68 in to our portable product. We've build low volumes of devices up to now with the STEVAL-ISB68GUI V1.4.1 up to now, but would like to ramp up our production and therefore requires to automate the process. Unfortunately does...
