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?

I2C address map for STUSB4500?

HiWhich registers can be read/write on the STUSB4500? What are the register addresses?The datasheet only mentions the NVM parameters and their default values, how do you set them via i2c?ThanksJM

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.

Configurations are as followI am using default OCV table and 660mAh battery (4.2v max) with <70 mOhm internal impedancefirst OCV value = 7788REG_CTRLvBattTWI_Write(1, BATT_GAUGE_ADD, REG_CTRL, 0x02);REG_MODEvBattTWI_Write(1, BATT_GAUGE_ADD, REG_MODE,...

BTA12-600B for Dimming of 240V Dimmer Light

We Are Using BTA12-600B for Dimming of 240V Dimmer Light.We Want to Know the Temperature Vs Ampere Graph so We can judge that if we pass 3A through the BTA12-600B then how much heat will dissipate and how much temperature of BTA12-600B. I Am Sending ...

STNS01: LDO Output protection

Having 2 power rails, 3V3 and 5V while STNS01 generates 3V3 (well, 3V1 to be exact) from 5V input (or battery), is it possible to feed 3V3 externally when STNS01 is shutdown? Is STSN01's LDO output reverse protected? Or will we need an ideal diode to...
