Hello,I use a STPM32 on a battery charge system. The STPM32 is associated with an ESP32 module.The driver used is from ST (V1.0, 17 may 2016).I want to detect some defaults with interrupt, and I configure the interrupt mask only for current and volta...
I have already using L9524C IC for glow plug controller. I have to must to learn that what is the maximum duty cycle value of Control Input (CI) PWM signal?And if I have apply continuous HIGH signal to Control Input pin, how L9524C works? Freq. is 40...
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...
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...
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 ...
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....
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...
Hi, I am designing a 25W power supply for the raspberry pi 5 for my battery powered project. The buck regulator I am using has a fixed 5V output and I want to use the STUSB4710 to offer 5V 5A to the Pi. How can I program the registers to do so via I2...
From what I can read on this diode it is from ST for sure, and it says VU beside the logo, the next line is M R, and the last line is GP922. Any help would be appreciated.
