Resolved! Heating on VIPER22ADIP-E
Hi STMicroelectronics team,I am using VIPER22ADIP-E to design 15V, 5W power supply with input supply of 230Vac with diode bridge rectifier.The schematics file is attached here,When i am loading it with 5W load, the IC VIPER22ADIP-E is get heated and...
SPV1050 -- best way to switch input power between low impedance source (USB) and high impedance sources (Solar, RF, TEG)
In my application I want to be able to charge a low mAh battery using the SPV1050's built in battery charging functionality (in buck/boost mode), but I want the ability to switch the energy input from a high impedance source (such as Solar), over to ...
STD12NF06LT4
STD12NF06LT4，Is there a "G" marking on the right top corner of the part? How can we read the DC from label? Thank you.
RHFL7913A negative LDO regulator current limit adjustment
Hi,I have a problem of adjusting the RHFL7913A negative LDO regulator current limit to about 0.5A by a Rsh resistor. I tried with 12.4 kOhm but no current limitation is seen even at around 910 mA load. Anyone happen to know the correct resistance val...
Resolved! FERD20H100S MTBF and FIT Reliability Metrics
Hello, I am trying to find reliability data (specifically MTBF and FIT) for the FERD20H100S. If anyone knows where to find it or could point me in the right direction I would be very grateful.Thank you,-M
STM32L0 boot sometimes fails on battery power - intermittent issue
I have an STM32L0 project that operates from a CR2032 coin cell battery. The board operates fine most of the time but there have been a few occassions where the power cuts out after a couple of hours or so and then the board will fail to boot up with...

STUSB1602 - Documentation request
Is there any documentation regarding the I2C registers of the STUSB1602 and the SPI interface?I cannot find information regarding the SPI interface anywhere, other then maybe reverse-engineering the driver.Is this available anywhere?
Resolved! I’m trying to identify an ST component.
I’m trying to find a replacement for this device from a light dimmer. I think it’s a triac, but the numbers on the front don’t match any search results, other than a similar request on this forum, so I’m hoping that someone can help!
TRIACs for Home AC Switching using T2035T-8G
I have been using the "Triac, SCR and ACS Simulator" to simulate the activation of a 10 Amperes load with T2035T-8G (as I am having issues with this component) and I was wondering why it shows a Tj extremly high (388ºC) if this device could handle 20...
