wireless power transfer
Hello experts!my GP is to design an offline DC/DC converter ( LLC ) for cordless home applainces similar to the attached file, now I am aware of how to design LLC for conventional Chargers (wired) to some extent, but i get compeletly confused when i...
Rise/Fall Time Issue with STW3N170 in H-Bridge to test High dv/dt test setup for our sensor using driver used UCC21330
I'm using MOSFET STW3N170 in an H-Bridge configuration along with TI’s gate driver UCC21330. During testing, observed an issue with the switching speed as the test is for high dv/dt Observed Behavior: Rise time ≈ 5 µsFall time ≈ 5 µs Test Conditions...
In the SPI protocol of L9305, how is the cnt bit of bit21 used
Hi, There is no specific writing description for the cnt bit in the manual.I guess it's the first time I've powered on and written 1. If I reset the chip through the reset pin, should the cnt be written to 1 after the reset or keep the negation of th...
STP08CP05TTR: Clarification on Using External Current Control for LED Dimming
Hi Sir,We have connected the REXT resistor with a value of 241 Ohms, which sets the current to 80 mA. I would like to confirm whether it is possible to use an external current control circuit to dim the LED.For example, in the case of STP08CP05TTR, w...
Basic Model vs. Electro-thermal Model of TVS Diodes
Hello,I have some questions about ISO7637-2 and ISO16750-2 transient pulse simulations using the basic model and the electro-thermal model of TVS diodes in LTspice.1) In a DC sweep simulation, I observed different IV characteristic curves between the...
STEVAL STWBC86TX programming
Hello, I would like to program a board with the initial configuration of the STEVAL STWBC86TX. To do this, I need two files: PATCH and CONFIG. Where can I download these files to the STSW-WPSTUDIO GUI of the test board we have?
Looking for STWBC2-HP Fixed Power Output Firmware
大家好，我目前正在研究基于 STWBC50-HP 芯片的 2W 无线功率发射器。我的目标是在不使用 Qi 协议的情况下验证硬件功能，用于学习和测试目的。我已经完成了发射器硬件设计，现在正在努力寻找一种无需 Qi 通信即可输出固定功率的固件，例如演示或示例项目，例如：STWBC2-FW-固定功率输出、或任何允许恒定功率输出（例如，19V 2.6A）而无需协议协商的类似固件。不幸的是，我在 ST 网站资源或 STM32Cube 软件包中找不到确切的固件。任何人都可以分享下载链接或提供在哪里找到此固件...
ST L4986A not working
We’re currently facing an issue with the L4986A PFC controller in one of our designs. The IC is not functioning as expected, and we would appreciate your guidance.:wrench: Issue Summary:• The IC receives all input voltages within the recommended oper...
TCPP03 compatibility with FETs that have a low Vgs(min)
We are looking at using the TCPP03 and TCPP01 for a system with a dual-role power port and a sink port. We want to use this dual MOSFET with both ICs (a dual MOSFET is needed for the TCPP01 to prevent backflow): https://fscdn.rohm.com/en/products/dat...
Resolved! STPMIC25 latching
Hello,I'm in the process of moving from MP1 to MP2 on my device. The latter, used STPMIC1 that suffered the startup problem as described in AN5861 and I had to go thru a re-design to include the latching circuit on my PCBA.Can anybody confirm that th...
