Clarification on STUSB4710QTR Configuration for 5V/5A Power Source
I just need some clarification regarding the STUSB4710QTR.I'm designing a USB-C power source where a USB 2.0 hub will supply 5 V/5 A to a USB device. The connected device is a USB cellular modem, which typically draws a continuous 5 V/3 A, but requir...
EN 60730-1 and BTA41-800BRG
Hi All,We are making controller for 3 phase heater. It is ON/OFF controller, with heater in delta configuration with mains 400 VAC (phase to phase voltage).Heater is always connected to one phase, while other two are controller with ST's BTA41-800BRG...
STSPIN948 and stepper motor
Hi,does anyone in the world have used a STSPIN948 with a stepper motor?I'm having many problems, also because of lack of documentation and examples.I need to control a NEMA 23 motor, but if it turns slowly it works, over 2 turn per second it hangs.I ...
L4985A_PFC issue
HiI am using L4985A for my 110W PFC design. During testing boost inductor current is getting distorted when i increase the load. And also, audible noise from the boost inductor. Here I attached the waveform. I used eDesign suite for designing and sim...
STC3115 - do we really need to use the RAM
HiI am looking into STC3115 for a device, powered by a LiPo battery. The battery is not removable, main CPU turns off during low-power states.Looking at the AN4324 system integration manual, it describes the procedure to use the embedded RAM to save ...
Resolved! Low side switch to drive 5V automotive relays
Hello ST Team, We are currently desiging an ECU, which require DO that can drive external 5V automotive relays. We have identified L9338(AEC-Qualified part) from ST for our design. Kindly confirm its selection and longevity of the part. Th...
ST1S12G18R Output Voltage Issue - Feedback Not Functioning Properly
Hello,I'm encountering an issue with the ST1S12G18R DC/DC regulator. I've attached the reference schematic from the datasheet and my PCB layout, created in Altium. As you can see, my design matches exactly with the reference schematic provided by ST....
L7987L Not working as expected
Hello All,I am using L7987L to generate +15V from 24V. I have 10 same boards wherein I have used the same circuit (see below), I am able to generate 15V for 2 boards but in rest it is generating 1.22V only. R191 is 6.8kohm and diode D36 is US1M-E3/61...
Resolved! VNH5019A-E- How to understand the thermal resistance (RθJA) in VNH5019A-E datasheet
I need to calculate and estimate the required thermal resistance and temperature in operation for thermal design. When I read in Section 3.1 of datasheet, I do not see the Rja I can use directly, instead, it presents a chipset configuration with vari...
Are WBC86TX, WLC38RX discontinued?
HelloCurrently, all information on WBC86TX and WLC38RX has disappeared from the ST homepage.Does this mean that the two chips are discontinued?I would like to know whether they should not be applied to new designs,and how long they are planned to be ...
