MARKING CODE of "L78L05ABUTR"

Hi. There is a question about "L78L05ABUTR" regulators. It's marking code is shown as "8C" in catalogue. But, It's actual product marking code is "8C033" (We bought "L78L05ABUTR" from Digi-Key.) I am curious what is right.

Triac control by pulse transformer

See AN436. I am using T1635-6G in a Hybrid Relay configuration following AN4993. Load is about 2kW at 230 VAC. Circuit works fine at with gate traiin of pulses (2kHz, DC = 50%). I want to trim parameters to optimum, at the moment transformer is make ...

when I use STC3115 why the SOC is not accurate.Using STC3115 and bq25898,when bq25898 indicates that charging is complete,but the soc of STC 3115 is only 43000,not 45688. The STC3115 needs to adjust? AND How to do it.

Resolved! Mouser SO# 490877 Hello, a customer is requesting clarification that the ICs we shipped them for P/N: VN7050ASTR are the correct ICs as the marking only shows "VS7050A".

The customer expected the full part-number as marking..We pointed him to the mfr label which shows the correct part-number and the marking.The hint in the datasheet showing that the marking is limited to 7characters with the last 2chars of the P/N be...

Resolved! Is it possible to use the SPIN3202 with a linear stage with digital end-stops?

I have a STEVAL-SPIN3202 board and I have a linear stage (2-poles, 3 phases). To prevent collision with the endings of the stage, there are connected two end-stops. (One on both ends).Is it possible to use the STEVAL-SPIN3202 board for this setup? Or...

Resolved! HI, I'm using a shield ihm13a1 with nucleo G431RB and DC motor, but I can't regulate the Vref, If I set a Vref = 1,6 (50% d.c) the motor doesn't move, I have set 80% d.c. to make it move. Any idea?

Resolved! What is the purpose of the internal low-side switch in LED5000? Is it a synchronuous converter? If so, then why is an external Schottky shown in the application diagrams?

Hi, I am new to a project with the STEVAL-SPIN 3201. If I connect the board via USB it doesn't appear as a disk. Is there a way to reset the board, to setup it up again? Thanks!

Is a back to back FET required in a USB-C Power Delivery compliant source application?

I have a USB-C Power Delivery source with a receptacle (no captive cable) . The output of the switching mode power supply and the USB-C receptacle must be separated by a switch due to the cold socket principle of USB-C.Is a single FET sufficient or a...
