Resolved! Can I get confirmation that B250 is the correct part marking for LD3985M25R? We are a contract manufacturer and need to confirm this information when assembling boards for our customer. Parts were purchased from Mouser, and bag indicates the correct p/n

Resolved! Hello, please help me identify the name of the chip. How can this procedure be carried out on your official website?

Resolved! Hello. My question would be: can I control the speed on the steval ptool 1v1 board with a pwm signal or just an analog voltage? Or it is possible to give a pwm signal to the analog input? Thanks in advance for the answer. Bela

In search of STPSC6TH13TI.

Resolved! L6480 data sheet says the /CS must be raised between bytes but Figure 19 shows it remains low for the whole message, so one piece of the datasheet must be incorrect as both cannot be true. What is the correct operation please

Current measurement and hall effet sensors in STGIB15CH60TS-L

Dear ST community Hello,I am using the STGIB15CH60TS-L for motor control, I have a question about the schematic in ST documentation.Could you clarify to me please about the switches sw7, sw5, and sw6 used in the low side transistors for current measu...

AC or DC input (ultra-wide input)to DC output SMPS circuit design ?

Dear ST team,I want to design an SMPS circuit with the following specifications:* Input can be either 33-265 VAC or 48-375 VDC (ultra-wide input)* Multiple DC outputs1.output : 24V with 0.7 A2.output : +10V with 0.8 A1.output : -10V with 0.8 ...

PM8804 VC high voltage set incorrect voltage level

I’ve build 5 boards using PM8804 and only one board seems to regulate the VC (Output of the internal high voltage start up regulator) according to the datasheet where the high voltage regulated drop below 6V when it detect auxiliary power detected hi...

i have received parts from supplier STN3NF06 however i have 2 different codes showing on the reels The new stock shows STN3NF06LSV1 The old stock show STN3NF06LSF2 i can find no reference to this on any datasheet online. can someone advise here
