How to read the Line Frequency and Power Factor in EVALSTPM34?

Hi All, I'm working on a project (Street Lamp), wherein we required some metering parameters. So, I've brought an EVALSTPM34 board for speeding up the development process. On the "STPM3x Evaluation software" I was able to read all the necessary param...

LDL1117S33R SCHEMATICS

Hello,I am using LDL1117S33R for one of my project. I want to convert 5 volt into 3.3V.Please find the attached schematics.Could you please verify the same ASAP?

ESC based on STEVAL-SPIN3201 and STSPIN32F0

Hello,I`m currently thinking of creating stripped down version of STEVAL-SPIN3201. I have a few questions before I can start with this project:Why is there STM32F103CBT6 MCU on the STEVAL-SPIN3201 evaluation board? I can`really see much purpose for t...

It the calibration for STPM32 performed at 50Hz still valid for 60Hz line frequency?

Dear all, we are using the STPM32, and we calibrate it with a 50Hz load. In some cases, customers need to use it at 60Hz. Is the accuracy obtained from the calibration still valid? On documents, I can't find this in formation.The only statement is: "...

Hi all, We are using fuel guage IC: STC3117IJT . when powerdown mode is activated It consumes around 2mA, but it should be 1 uA. What can we do to minimize the shut down current in STC3117IJT? Regards, Nirav K.

While we have set the register REG_MODE to 0x0B as well as 0x01 to minimize the powerdown current but no luck.As shown in attached picture we have observed below scenario.1) the pulse of 50msec to 440uA by every 11sec  2) pulse of 240msec to 210uA by...

How to calculate soft start time for buck converter ? I am using L4973 Buck IC with Input voltage in the range 30-40V and Output 23V.

How to enable boot mode to write in the flash memory of SPIN 32F02 board??

Hello, I have the spin32f02 board, which I am trying to write the 6 step algorithm into flash memory, I followed all the steps, and configuration available in manual, but it didn't work.Whenever I plug in the board, uses only 4kb of RAM and I need th...

Problems with changing the torque regulation torque

Hello,We have a problem with the controller wehn changing the torque regulation torque. This problem happens randomly but very frequent. When the motor stops we change the current regulation torque from 1300 mA to 250 mA. And some times we can see so...

We would like to use STPM32 for metering of streetlights.

Does STPM32 provide Line Frequency and Power Factor as parameters that can be read from internal registers?I did not find this in datasheet.
