Hi.. It's possible to know the exact code of this component?Thank you so much

I'm currently working on EVAL-SCS001V1. I'm able to switch profiles 9V and 12V. But whenever I choose profiles of 15V and or 20V the output voltage doesn't changes to either 15V and or 20V and it shows explicit contract to 5V. Please help on this  issue, I have tried every possibility to select the 15V or 20V profile but it doesn't worked.

Hello, STMicroelectronics team: Currently, our solution is to communicate with SPI1 four wires on TC233 and SPI four wires on L9301 to read the fault diagnosis information of L9301. The problem we are currently facing is that when I am not externally connected to the load and do not add a driver to L9301, the diagnostic information is read through SPI. However, the 8-way low side register and 4-way high side register are unable to feedback an open circuit fault, There is no open circuit fault feedback in the SR1-SR12 (0x11-0x1C) Driver status register, and when I manually create a short ground fault, only the high side open tube has fault feedback. When I manually create a short power supply fault, only the low side has fault feedback. However, I feel that this power supply fault is problematic because according to the data worksheet, only the high side can report a short power supply fault, and the low side cannot report a short power supply fault. Is there a routine for SPI to read f

안녕하세요VN750PS-E 드라이버를 통해 모터를 구동하는 회로를 작성하겠습니다.INPUT에는 5V MCU 신호가 있고 12V 전압이 VCC에 연결됩니다. OUTPUT에는 모터가 연결되어 있습니다.하지만 STATUS 핀을 처리하는 방법을 모르기 때문에 이런 글을 남깁니다.데이터 시트에 따르면 Rprot는 10k 크기의 저항으로 연결되며, 그 전에 MCU의 5V가 아닌 전원 공급 장치에서 추가 5V가 나오는데 맞습니까? 누구든지 좀 더 이해하기 쉬운 그림을 말하거나 그릴 수 있습니까? STATUS 핀을 제대로 연결할 수 없었던 현재 상황을 게시하고 있습니다.감사합니다.

Hello, I would like to use the current sensor function of the VN920B5HTR-E driver.According to the data sheet, when the Rsense value is used at 10k, it is expressed as 4V when it is 10A above 8V.I use a load of 12V and up to about 8A, so can I use 10K?? The maximum voltage by detection should be less than 5V.This is because the ADC_CURRENT value must be connected to the port of the MCU.I wonder if this circuit design method is correct. I'm asking because I'm curious about the figure because I think it's too big to use as a value for shunt resistance.  

Hi Support team,Could you help us by providing the 3D model of the AECPACK SMIT package? We need to ensure our design mechanism's size for cooling. Thank you!

not any data available in Google pls identify the components.

Hello as I am using Nucleo-L476RG and sx1272mb2DAS I want to mesure consumption with LPM01A. The probleme is when the consumption is very high because the part of Programmer is not isolated. Also the limitation of using an external source of power 3v3 I have to cut the board. Is there any other solution to see the real power consumption of the node.

Hi all,I have observed a phenomenon in my new design where the ripple is significantly large at light loads but decreases to very low levels when the load increases to its maximum.I have attempted to change the frequency and add additional capacitors, but these measures have not resulted in any improvement.I am seeking to understand the cause of this behavior. Could someone provide assistance with this issue? Thank you in advance. 

Hi,Is any PLECS model available for ACEPACK DRIVE power modules? Even under NDA?Thanks

Hi, I'm working on a project and have a question for youFirst, ARC mode is said to increase the radius of X and Y axis of wireless charging by up to 50%.1. why is it CFG register, is the mode always active?2.the setting value is steps of 10mV and I wonder what is the relationship between this and ARC mode?3.GUI related question, how can I take memh files of CFG files and patch files and convert them to hex code and update them to firmware?I have implemented the firmware update, but I want to update it with data from files created in the GUI. 

could you help me to know why the dimension differnet in 2 datasheets while the supplier package is SOT-23 with pincount 3 pins   > the dimension for first diagram is  ( Length = 3.04(Max)    -    Width = 1.75(Max)   -  Height = 1.3(Max)  ) > the dimension for second diagram is  ( Length = 2.9    -    Width = 1.3   -  Height = 0.95  ) i think the 2 parts should have the same dimension because it have  same package and pincount . why there are tolerance in dimension and not unified for same pincount and supplier package .   Thanks          

Hello,Can someone from ST actually provide me with an STEVAL-WLC38RX ? This simple charging board is out of stock everywhere. I've ordered on mouser weeks ago, yet the pending dates seem to be BS as the dates go by an the part is still on backorder.

Hello,I am conducting tests using the STEVAL-L99615C evaluation board. Despite following the L9961BMS Quick Start Guide and User Manual, I am encountering an issue with Demo 1. As shown in the attached picture, the message "No device found" continues to appear. Even when applying 20V to the B+ and B- terminals, the same issue persists.I have ensured that the hardware jumper pin settings match those specified in the Quick Start Guide. However, I am concerned that the difference in versions might be causing the problem. The version of Demo 1 in the Quick Start Guide is 1.1.0 (July 21, 2023), while the version I am testing is 1.3.0 (December 1, 2023). Could the change in version be causing this issue?Thank you for your assistance.

Hi,I am using LNBH23 and LNBH26 for our LNB control. And I have the following question:1) When I power LNB with 18VDC, I can enable/disable 22KHz properly.2) When I power off LNB, I can't enable 22KHz.Anyone can tell me how to enable 22KHz without LNB power applied?Thanks,Christie

I am writing to request specific information regarding the MTBF (Mean Time Between Failures) of the L7805 positive voltage regulator component. We are considering using this component in a critical project and need to assess its reliability for our design.I would greatly appreciate it if you could provide the exact MTBF value or direct us to where we can find this detailed information.Thank you in advance for your assistance

ReleaseSW command fails to bring the motor out of the switch. Is there a reason the ReleaseSW command fails to bring the motor out of the switch? The software reset sequence I follow is as follows: 1. Issue software ResetDevice 2. If the SW is NOT LOW             GoUntil() // move until the sw is low 3. ReleaseSW() 4. Move( offset)   The issue observed is that when the SW is already low out of reset, step 2. is bypassed and step 3. fails. Any idea how to fix the issue?

Hello!I'm trying to make a open source test board which allows people with an Arduino to try out using the STDrive101 chip. However, I'm running into an issue where it appears to be entering fault mode and refusing to leave it (leaving all mosfets disabled and making the board more or less a brick). I've attached the schematic (and here's the repo with the Kicad project and arduino code https://gitlab.com/charlesrwest/stdrive101testboard ) but I've also put a brief rundown on the setup below:Operating voltage: 12.3 volts2 massive 1000uF capacitors to keep source voltage steadyCP set to ground to disable overcurrent shutdown (so CP never higher than Vref)DT/Mode connected to ground with a 200kOhm resistor (should result in dead time of ~2000 ns).SCREF left floating to disable Vds monitoring protectionVS has a 100nf bypass capREG12 has a 22uF cap and a .22uF cap (seem reasonable?)NFault left floating, but adding a pullup resistor doesn't seem to change anything (it pulls down)I

Hey guys. Could anyone help me with the datasheets for these two ICs drivers?

We selected the Triac ST# T1635-600G for refrigerator project, to control the compressor (inductive loads). Tested T1635-600G, the heat is very serious when passing 16A current, even using a heat sink temperature is more than 100°C. Therefore, I want to use T3035H-6G. May I ask how much heat sink is required for this model when it passes 16A? Or do you have app recommendations? Are there any guidelines on heat dissipation? Thank you!

 Hi Team i designed the schematic shown below for my automotive GPS Tracker Screenshot 2024-05-27 1500131355×883 62.2 KBHere i used diodes for droping the voltage main regulator D17 used for 5 to 3.8v approx.auto bat circuit D7 used as 4 - 3.8v approx.so I'm Just thinking that is it the correct way to do this for long runor any better way to do thisplease give your suggestions and recommendations.Thanks in Advance  

Hi, I would like to adjust OCV parameter in STC3115. In datasheet I see equation for calculation OCVtab value. But I don`t understand it. If I have STC3115IQT and I can set 100% SOC from 4.313 V to 4.22V.(4.22-4.313)/0.55 = 0.05 but to register I can only set numbers from -127 to 127 . Please how can I correctly calculate OCV offset value.thx

Hello I want to use STEF12PUR (electronic for 12V) and have following question:1. What is the response time of this fuse (how fast it will trip in case of over current)?2. For me not clear difference between ILIM and ISHORT?3. If I want to set fuse for 2A according paragraph 5.2 I have to use 47.5 ohm resistor (by using formula: 95/2A = 47.5 ohm). But why graph 13 shows much higher values for this resistance - ILIM seems to be even ~3A?  Thank you. Alex

Help me find the diode.

Dear all,I am a BMS engineer looking for an automotive-grade BMS solution. Is L9961 good enough to develop an automotive-grade BMS for onboard battery pack monitoring? Do you have any other suggestions?Thank you very much.
