Hi All,I'm working on driving sensorless BLDC motor by 120 degrees trapezoidal control.I'm stuck on to get back-emf voltage like below figure:My result is like this.And the circuit used for voltage sens part is as follow.I don't know if it's a circui...
The SPICE model file for the product SCT040W120G3AG downloaded from the official website is incomplete, it only has the LIB format file. Can someone provide me with the complete SPICE model file? Thank you!
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...
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...
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...
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...
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...
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?
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...
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...
