Poly fuse原理
WebJul 16, 2024 · There are no fuses in the general USB 3.0 controller (unless you count an electronic fuse circuit as a fuse). The fusing is provided by a mosfet that is built into an IC (host controller or external mosfet) with a current level detection circuit. If the current goes beyond the spec, then the circuit is shut down. Web芯片Trim之Fuse(网友总结)_模拟IC设计交流_新浪博客,模拟IC设计交流,
