Resolved! Start up L6981(C33) problems
I'm using the L6981C33DR bug converter to convert 24V (from an SDR-120-24 power supply) down to 3.3V. However, I've had instances where the regulator overheats and "exploaded".The circuit only needs to supply around 100mA at startup, so the current d...
Issue with STUSB1700 Negotiating BMS with SYNC
Hello,I am currently integrating the STUSB1700 into a custom circuit board design. However, I am facing an issue where the STUSB1700 is unable to negotiate the Battery Management System (BMS) with the SYNC protocol.To provide more context:The Saleae ...
STWBC2-HP Qi transmitter and CC Handling with Macbook Pro M1 and Mac Mini while using USB data lines
We are developing a wireless charger with additional wireless-to-USB gateway functionality. We have a design where we use the STWB2-HP as a wireless power transmitter - works fine most of the time. In parallel, we implemented an ESP32-S3 with BT and ...
Resolved! STEVAL-WLC38RX and STEVAL-WBC86TX Evaluation Board Firmware Source Code
Where can I find the source code for the firmware on the STEVAL-WLC38RX and STEVAL-WBC86TX boards? I'd like to start there and make some modifications.Thanks.
VNF9Q20F and VNF1048FTR: How to get I2t Curve
Hello,I am working with these two IC's to try and create an SPI programable power distribution module. For the VNF9Q20F I understand that you set Inom and Tnom to get your desired curve. My question is how do you know what Tnom you would need to sele...
SCT1000N170AG_V2 SPICE model uses help
Dear Engineer: Is there an error in the SPI model of SCT1000N170AG_V2? Why do I have such a simple switching circuit, and when SCT1000N170AG_V2 is turned on, the waveform is like this? Theoretically, the conduction should be 500V, and the output shou...
How to set up the SPI communication with powerSTEP01
Hi beloved friends of software architecture,i try to programm an SPI communication protocol of an STM32F373CCT6. It should communicate to the powerSTEP01 in order to move a motor. The problem is that i dont get any answer of the powerSTEP01. Did i d...
