Hello, I am creating a board using the STUSB4500QTR and I saw something on a video that confused me. I want to use the IC to take in 100W (20V/5A) and output three different voltage rails: 3, 3.3 and 3.7. Each will have a fairly large curren...
I bought the STEVAL-WLC99RX evaluation board for the STWLC99 Qi 1.3 compatible receiver and cannot find a location to download the GUI to program/monitor the receiver. The page that I am pointed to (https://www.st.com/en/embedded-software/stsw-wpstud...
@TDK , @Peter BENSCH we are facing SPV1040 IC failure (burns) in the field, after around 3 months of installation, attached schematic and our solar Panel speciation Voc:4.55V, Vm:3.85V, ISC:1026mA, Im:950mA.Battery spec - 9000mAh, 4.2V Lithium ion.
Hello ST team and community,I’m currently trying to recreate the AN5287 reference design on my own PCB for learning and testing purposes.However, I could only find the application note (AN5287) document itself, and it does not include the PCB layout,...
STWBC86 TX can be use for bi-directional communication, when rx send PP-packet as QI defined, STWBC86 update to 1251 version and use GUI to read i2c reg address 0x0100, and it can read RX PP-packet. https://github.com/STwirelesscharger/STSW-WPSTUDIO/...
We are using 2 MASTERGAN1TR to drive current across an inductor.We are seeing damage on the body of the chip nearest the low side ground connection with a PWM Frequency of 250KHz and a 12% duty cycle.Before the chip fully fails the current decreases ...
Hello STM Community, I'm currently working with the VNQ9080AJTR Quad Channel High-Side Driver, and I'm encountering a couple of issues that I hope someone here can help me resolve 1.Output Voltage Regulation: With a constant VCC supply of 12V, the ou...
Hi all. I've made a dedicated PCB that should control auxiliary lights of my motorcycle. I use CANBUS information by MCP2515 module and using Arduino Nano digital output pins to directly control input pins of VNQ9080. I assembled all elements on the ...

Is there a way to read the motor position while it's moving, such as with a command like "run," "goto," "move," or any other command from the Powerstep01? Does the motor need to be stopped for the motor position to be read correctly? Currently, when ...
