Hello,On my custom designed PCB, there is a USB port for battery charging and programming ESP32 microcontroller. When I plug in to the PC, I get "USB Not recognized" message. In addition, the two LEDs are light up. In the datasheet of the charger IC ...
Hello There! I have bought EVAL- SCS001V1 sink device for my application in which I need the output as 12V/2A from the mentioned sink device. I came across below problems and I seek help on it. 1) Problem related to STSW-STUSB002 GUI version 2.0. The...
Hello everyone,I'm reaching out to the community because I'm encountering an issue with a Wireless Charger board we designed, based on STWBC86 and a similar architecture to the STEVAL-WBC86TX evaluation board.The main problem is the Power Transmitter...
I am using STEVAL-ISB017V1 (evaluation board of STC3117) with i.MX8MP board with linux. I am able to detect the IC and getting the data i.e. Voltage, temperature, current, and capacity. But the data for Current and capacity is not as expected. Curren...
I have assembled PFC and LLC circuit of STDES-3KWTLCP reference design. I followed the procedure as described in the document to assemble whole circuit. When we gave AC voltage to PFC, resistance R154 gets heat up and eventually burn out. I double ch...
Hi @Peter BENSCH can you help me how to modify the STEVAL-ISV020V1 to make the VEOC up to 5.3V?
Hello everyone,I have the STEVAL WBC86TX and RLC38RX evalboard here and I am currently testing them with the STSW-WPStudio.In my application I want to implement an custom inband communication between RX <--> TX. It seems that there is the possibility...
HelloCould someone please help me with information on how to define the values of the capacitors and resistors seen in the figure of the typical circuit? Thanks
Hello,I was wondering why a 1K resistor is connected in series with the VSPI pin of the EV-VNF1048F.The pin has a current consumption of 3mA. So does that make a drop of 3V ?
Hello,I was checking the evaluvation board of VNF1048F for a efuse application to control motor drive. I wish to know how the capcitors for the charge pump selected in the evaluvation board. I am able to see 470nF in the evaluvation board schematics....
