Class 1 Accuracy meter ic

I am Anees PK form Riodlogic ,India-Kerala.We have planned to use STPM34 for Energy meter IC to measure the Energy consumption for EV charging stations for the Billing application. So please confirm this IC can provide 1% accuracy on Energy measureme...

Two application questions for powerSTEP01 - how to externally power the core correctly and how to drive brushed DC motors?

1. Power supply to the core logic: What is the right way to do this such that the Vs motor supply can be turned on and off while leaving the logic running? The datasheet leaves much to be desired (which are input power and output power pins is confus...

How to use the VIPER222LSTR IC?

I want develop a power supply board for my STM32 project.For my power supply board I want use a VIPER222LSTR converter but reading the datasheet I realized that some resistors and capacitances values not are specified.How to use the VIPER222LSTR IC?T...

STWBC-EP, STEVAL-ISB044V1 based design Communication issues

ST,My team and I have designed a Qi wireless Transmitter (TX) based closely off the STEVAL-ISB044V1, sharing the STWBC-EP controller and the overall block diagram. The principle difference is more robust front end protection, (Fuse, zener, RPP, TVS)...

forward/backward/brake with PWM signal in STEVAL-SPIN3201

Hello all, I'm interested in getting the STEVAL-SPIN3201 for my robotics project.I'd like to know if it's possible to control it with PWM/PPM commands, and if it is, how to perform the connections (it's not shown in the datasheet, maybe when buying i...

What is the maximum speed in microsteps per second of the POWERSTEP01 when in STEP mode. I am currently using x16 step mode. Also will motor move faster if I switch to x4 microstep mode.

STC3100 with Arduino

Dear ST-Fellows,I'd like to use the STC3100 with the Arduino IDE but my knowledge is too little to get it working. I looked at the libraries provided here:https://github.com/st-sw/STC3100_GenericDriverCould you please tell me how to adapt the files t...

Hi, Using the "STEVAL-ISB68WA wireless power receiver evaluation kit" , Nominal chip idle current consumption is 17mA using the default setting programmed into the OTP memory at power-up. Is it possible to reduce this current using the STSW-ISB68GUI ?

What are the topology used in EV charger and which topology is most common in market?

I am vikash Kumar. I am new in application engineering. I am interested to lean more about EV charger and SMPS design. Please suggest me about some application notes or online webinar to enhance my knowledge. Thank you
