STPM066S OTP Programming Application Note / Example Code
Hello,I am trying to set up an STPM066S PMIC via OTP (One Time Programming), but without success so far.I am struggling a bit with the description in section 6.7 of the STPM066S data sheet (Rev. 2).a) Is a more detailed application note on OTP availa...
30W Flyback AC/DC Converter with PFC and isolated output
Hello,I have to design a power supply for our new product. I would like to implement this with a flyback converter. The biggest las on our board is the IMX.8, this changes its power profile depending on the requirements.Key points of my design:- 230V...
Resolved! I need a help to identify this part
Hello! I have two components (in SMB package probably). The markings are:1) ME G3 202 (no polarity stripe on package)2) EE G3 223 (with polarity stripe)Can you help me decipher what these elements may be and what may be the difference between ME and ...
Resolved! Regarding ic current to voltage converter
Is there any IC available to convert 4~20 mA current signals to 1 to 5V DC Voltage signals in the SOIC package?
LD1086 DPAK pin configuration
Do we have a clear Pin Numbering configuration for this component as pin numbering which is 1,2,3 the datasheet did not clarify clearly.
Low Power Measurement with X-NUCLEO-LPM01A
Hello Dear Community, I'm trying to learn how to use the X-Nucleo-LPM01A for a Bluetooth application. I am using Nucleo-WB15CC and watching your low power measurement application videos for this card. And I followed all the steps correctly, but I cou...
L4981BD output reference voltage
In the application note for one of ST parts (L4981BD) and it is mentioned that the output voltage can be calculated from the following formula: But in the datasheet, in Figure 9B, the given output voltage does not match with this formula: Does anyo...

Problem with estimating the number of TVS diodes in the clamping circuit
I am designing a clamping circuit for an IGBT driver such as ABB 5SNA 0600G650100.Between the collector and the IGBT gate there will be a set of TVS diodes with a Schottky diode at the end. The gate will have a 6.8k pull-down resistor to the emitter ...
Overvoltage suppresion by clamping circuit in IGBT driver
I am designing clamping circuit for IGBT driver. The max voltage is 4800V. I was thinking about using STTH112A diode. In the datasheet, there is no information about thermal resistance - junction to ambient for SMB or SMBflat version. How can I asses...
