Hello ST Team,i am developing some projects and i need Energy management chips.. i bought the X-NUCLEO-IPS02A1 and the NUCLEO-F401RE so i could you use your examples in thepackage X-CUBE-IPS02A1.The Problem is i can't download the software package be...

Buck-boost, 3v to 6.4v in, white LED drive out, 3A, how to handle the high end of Vin with a buck-boost

I need to run a while LED (output voltage range from 2.5-4.5v 4A surge, 3A steady state) from a battery source that can range from 3v to 6.4v in. So it's a buck-boost. I haven't been able to find a buck-boost that has a Vin higher than 5, with an abs...

I believe there is an error in AN5114 Section 3.3.1 where R1+R2 is calculated: seems like the V_photo term was disregarded. Was there then higher ripple measured across the TRIAC than was expected?

Hello, dear colleagues! I didn't find any references to the marking and datecode of the LD1117S12CTR component in the documentation.

The first question is: does the LD12 label correspond to the LD1117S12CTR part number? The second question F928 is a datacode? If so, what date is indicated here?

I have just increased the baud rate to 115200 and I am facing a lot of overrun errors. How do I fix it? The code looks optimized.

Configuration advice stc3115

Hello,I have an issue on my stc3115, I can read the battery voltage and the SoC, but the SoC doesen't update (the voltage is udpated well).Here is the schematic of my PCB:For the moment, I am using a battery with two wires, "therm" is left floating. ...

ı am reading wrong Current value at STC3100. I need help to get right Current Value.

Hi,I attach my Power Side of Project Schematic.I will use STC3100 IC at my circuit. I will use Li-ION AA type Cell in my circuit and I charge my cell externally on charge device. So ı don't use STC3100 while charge status monitoring. I will use STC31...

Why and how is PWM implemented in Field Oriented Control (FOC) ?

Hi everyone, I am trying to understand and implement FOC algorithm in MATLAB for a PMSM. I understand we are converting the 3 phase stator currents into 2 time-invariant stator currents: (direct and quadrature currents or Id and Iq, respectively). Bu...
