Dear ST/forum team,Would be possible to know the Marking Code of the following MPNs?VNQ7140AJTRVNQ7E100AJTRMany thanks in advance
Resolved! powerSTEP01 motor current unstable in one direction
I have a powerSTEP01 driving a stepper motor with the coil current set to 2A. However, the current flowing in the coils is unstable when it is flowing in one direction:Sorry about the image quality - I have an old 'scope, so had to use a photo ;)The ...
Resolved! STWLC38 not working
Hi! We have designed a custom board using STWLC38 but its not working. We also have the Evaluation kit of STWLC38 and Im using the same coil to test my custom board. Im getting roughly 0.6V at VRECT pins after nearly every second. I aslo have attach...
Resolved! AEK-POW-BMS63EN reset state
Hi,I am working with a battery pack and the BMS. I have connected everything correctly to the board and after a first run everything seemed to work properly, the board was receiving commands from the MCU through the translator ISOSPI, and the green l...
Looking for STWLC89 datasheet
Looking for datasheets for the STWBC2HP and STWLC89, do these exist? I can't find them anywhere on the internet
SPV1050 input current specifications
Hello,I am planning to use the SPV1050 in buck-boost configuration.According to the datasheet, in this mode the charging current (I_batt) has a minimum value of 30 mA.I have two questions:Why is this specified as a minimum value? Can the actual charg...
Flyback with VIPer26: Snubber overheats, but no visible Vds spike. Low Vout.
I am debugging a VIPer26-based flyback converter designed, which fails to regulate and is stuck at a lower voltages. The primary issue is a severely overheating RCD snubber resistor, indicating excessive power dissipation. Paradoxically, the Vds wave...
Is it possible to develop a 150W, AC85-264V power supply unit for LED lighting using HVLED001A?
Edited by ST moderator. Please use English language in this community. HVLED001Aを使用して、150W、AC85~264V、力率0.95のLED照明用電源ユニットの開発は、可能でしょうか? 可能な場合、効率は、どの程度になりますでしょうか？ 参考回路例等がありましたら頂けませんでしょうか？ 電源ユニットしては、非絶縁でもOKです。 150W品でコストをできるだけ安くするには、どのような方式が良いか、制御用ICも含め...
L6494LDTR
Hello I am using the L6494(14PIN) as a driver for a high and low side FET in a half bridge arrangement. My DC volts can be anything from 120Vdc to 220Vdc. and current up to 17AIs there anyway to determine the breakdown mechanism if I do not momentari...
