STPM32 triggers interrupt for non masked bits.
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...
L9524C Control Input Signal Max. Duty Cycle Value
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...
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...
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! 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....
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...

How to set STUSB4710 PDO profiles
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...
Resolved! Looking for datasheet on diode
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.
