Connected discovery board to COM port. Using Demo bin file, have been able to view data with serial monitor. When I connect using Unicleo GUI 1.25.1.11665, COM port message states successfully opened. Unable to view any other data. Firmware: Expansio...
I require assistance with the design of the battery charger schematics involving the L6924D. Referring to the documentation (https://www.st.com/resource/en/datasheet/l6924d.pdf), the pull-up resistor R3 is 1K, and the NTC tuning resistor R9 is 470 oh...
I want to buy a wireless charging IC like STWBC86JR, but the data sheet says that it should be within the standard frequency of 110kHZ to 205kHZ, so can't I use it with a resonant frequency of 13.56MHz? Is there an IC available on that frequency? Is ...
Hi,We have PCB where STSPIN840 is connected to PIC32MK1024MCF100 and DC motors connected to respective OUTX pins. Getting PWM,PH(high),EN(high) when we are checking signals in CRO but OUTX1,OUTX2 both as 3.3v or one 3.3v another 12v sometimes. Accord...
Hi. I am currently evaluating the STEVAL-ASTRA1B as a low-power LoRaWAN-GPS tracker. My goal is to have the device wake up every 10 minutes to send a GPS position.I am however facing some problems getting the current consumption down to the advertise...
Hi, We are planning to use SCTHS300N75G3AG Sic Power MOSFET in our design. For this STPAK package MOSFET please provide Thermal model, PCB guidelines and Heatsink or Mechanical model.
Hi all, In SCTHS300N75G3AG Sic power MOSFET data sheet mentioned that 8.8mΩ Rds constant over maximum temperature. But in graphs Rds(on) reached to above 1.3mΩ. So, which value we need to consider for power dissipation calculation.
Hello, Sorry if this post has the wrong label/location. I have a problem with L6207 dual bridge motor driver. I am using stm32f031k6 mocrocontroller and L6207 to control two motors. While using the devices on evaluation boards they worked perfectly. ...
Hello,Ive designed a PCB with a STUSB4700QTR as a source following the datasheet ref design. The scope was to use the board as a charger with PD.When I plug a USB C phone on my source connector, the board deliver 2.2A at 9V on VBUS and the phone char...
