Resolved! STUSB4500 – I²C Pullup with No VBUS/VDD Applied
Hello,I am currently designing a battery-powered device that incorporates the STUSB4500. I have a question regarding the I²C pins: specifically, whether it is safe for these pins to be pulled up (via the system microcontroller’s pull-ups) when no vol...
ST MFU C104 diode info.
Help please!I'm unable to find any info on this diode from an old Siemens Siplus 24RCL PLC controller. Pictures attached.The diode shorted closed. I'm assuming because, someone hooked up the supply backwards!The only marks I've found are "ST MFU C1...

TS514IN
Is this part Non-Rohs? Date Code 0234. I see the newer part TS514AID look to be Rohs. Where can we look up part's to see if they are Rohs or Non-Rohs?
Parameter Definitions of L9678P
Hi,I'm using L9678P. I’d like to confirm the specific definitions of these parameters:Is 1~10KΩ the detectable range?Are the conditions in the "Condition" column strongly correlated with the parameter values?What does "Equivalent to resistance range"...
Problems getting output from the STW81200
Hi, all. I've been beating my head against this problem for a few days now. I'm not getting any output from an STW81200 frequency synthesizer. I used the schematic from the eval board except that the reference is a crystal oscillator. Power is suppli...
Resolved! MIPI_DSI ESD protection
Hello, this is the ECMF4-40A100N10(MIPI DSI ESD protection). I want to implement it in my design and I was wondering if it matters to connect your positive differential pair signals to D1+ and D2+ and negative to D-. Or can acually flip them? So I c...
