Hello community, Question is related to application note no. 308

Please help to use two anti-parallel SCRs in place of a single triac ? Regards and thanks in advance.

GPIO interrups every system tick

Hi all,I am using F303re to control an e-bike motor. I use GPIO PA6 connected to a speed sensor located on the wheel of e-bike.Every time the wheel takes a loop, an interrupt is sent from the speed sensor. Below is GPIO setting: GPIO_InitStruct.Pin =...

Can Qi 15W charger be used for charging 5W or lower products?

Hi. Have an open support ticket on this request but so far no reply so perhaps staff is on vacation. We are considering the ST devices for a pending product roadmap.Can the STWBC-MC kit be used for charging portable devices (watches, fit bands, etc.)...

Dear Sir/Madam, My question is related to your application note no. 308

I wish to use two anti-parallel SCRs for controlling a transformer with specifications of Pri:220V, Sec:7V, at 3500 amps. Is it possible ? What changes , if any, are required in the circuit ? Please help.Regards.

Starting of STEVAL-ISA147V3

Hi everyone, i bought STEVAL-ISA147V3 to understand well D-SMPS. At first try, i didn't connect fan to output load, so the fuse blow and some diodes at PFC circuit (D9, D12 and D13) become short-circuit . Then, i realized i should connect load to out...

Hello, I'd like to know why is STLD41 limited to 4 strings and could more strings be added if low current LEDs are used? Warm regards!

what's this diode type?the silkscreen is MV 63 746

How is this part marked, LD2985BM33R. What is the required marking code? We see this on the part, "B533". Con you confirm that this is correct marking code?

Hello, I am working on STC3117 for voltage and SoC detection. So far I am able to get voltage correctly but current values and SoC are wrong. Please check configuration if anything wrong.
