Does anyone know where I might be able to find a ST90E158-EPB programmer or equivalent? I need to program an ST90T158M9Q6.Thanks.

For the project I am doing, I have to make a solar charging circuit. So, I chose SPV1040T as a DC-DC boost converter. For this feature, I used eDesignSuite to create a solar charging circuit. The circuit should convert the 3v from the solar panel into 4.2v. After receiving the PCB board, I found that the circuit is not working. I have been trying to figure out what went wrong for last one week. But I couldn't. Could anyone please explain how SPV1040T works exactly?. It may help to figure out what went wrong in my PCB board. Thanks

Hi All,I am trying to program STNRGPF01 (EVAL-IPFC01V1), but I have no success so far. I connectedFTDI serial cable to programming connector, but STNRGPF01 programming tool stays in a loopwithout any results. I also found some ld post about this, but it seems, that these pages does not exists any more. Are there any more detailed data available how to program this devices.Thanks and best regards,

Where can we buy this STHV748 and STHV 1600

Hi,I would like to know the power dissipation of "STP6N120K3" under normal operating conditions or the formula to calculate PD and its "Thermal resistance between Junction to Board (°C/W) -RθJB" which is not specified in the datasheet.

I purchased several X-NUCLEO-IDW01M1 expansion boards. Some boards operate normally, while others reset approximately every 3 seconds and do not operate normally. I don't know if it will help but attach the log.

I have comunucation 485 when start the aplication after 10s begin error "FE"​.Baudrate1152008bitsNine paratyI use transiver maxin 485 and pin "DE" by hardware.​

someone knows it? MTGP437

Hi,I wish to use ACST310-8B in light dimming application.1. As shown in typical diagram of Phase Angle control, in the datasheet of ACST310-8B, can we avoid using choke/inductor in series with load?I believe this choke/inductor is needed for di/dt protection, EMI protection. Here lighting load is incandescent lamp.Reference: Figure 17, Page 8 of 14URL: https://www.st.com/resource/en/datasheet/acst310-8b.pdf2. Since this part is mentioned snubber-less, can we avoiding snubber circuit?Reference: Please refer "The circuit can thus be simplified, with no need for MOV or snubber circuits."URL: https://www.st.com/en/thyristors-scr-and-ac-switches/overvoltage-protected-acst-series.htmlAlso please find attached schematic “Phase_Dimmer_Schematic_using_ACST310-8B.png�? for your reference3. Is there any better way to protect ACST310-8B from damages caused due to accidental short circuit/excessive current other than fast blow glass fuse?Thanks in advanceRegards,Dinesh

When we wrote data at 0 location, same value getting reflected at 32768 and vice versa. Same behavior for 65536 and 98304, 131072 and 163840, 196608 and 229376. Not sure why it is writing at two locations same information even though we have written at single location. With this, we are unable to use 2Mbit size, its getting reduced to 1 Mbit. Which is a problem for us to proceed further on project. We are in difficult situation to go for another revision of board.

I am attempting to set the output states of an L9825 using its SPI interface, but no matter what byte is transmitted, the returned diagnostic byte is 0x88 and the output state is unaltered.clock frequency : 1 MHzclock polarity: lowclock phase: data changes on rising edgetransmit order: MSB firstNON1/2 pins are held highnRes is held highVcc: 3.3VWhat am I missing?

This driver is used (2 per module) in a fairly new product we have been shipping 10k modules in past 6 months. Until recently, we have had no driver failures. Now we have two returns from a customer with a driver failure on each.On one unit, one channel of a driver turns on when the input goes high but does not turn OFF when the input is removed. On the second unit, one channel of a driver does not come on when the input is high. Additionally, the inputs are typically driven high by applying 12V through a 10K ohm resistor. The inputs usually clamp around 6V. On this channel, the output goes all the way up to 12V - there is no clamping at all.By the way, 1. The output is OFF initially. It comes ON when the input is asserted and will remain ON until power is removed.2. VDRV is nominally 12V.Have you ever seen this type of failure and if so, what was the cause? NOTE: This question and answer originated from a customer support case which was handled

I'd like to use the x-nucelo gnss1a1 module with the stm32h743zi2 nucleo board. Am I correct in thinking that there is a way to convert an example project that the x-cube gnss provides for the stm32f401re to be usable on the stm32h743zi2?   If so, I imagine it's either a relatively complex task of porting over to the h7 board or a very tedious task of manually porting over.   Could someone shed some light on this for me?

Hi,I am trying to design a power supply using eDesignSuite, having universal input from85~265VAC/50Hz and having 1 isolated output 10V@15mA and two non-isolated outputs 15V@75mA and 3.3V@50mA (flyback converter). But I am unable to design both isolated and non-isolated outputs in eDesignSuite. Could you please help me in this regard?Best Regards,Anayat
