产品详情

12V, 5A Automotive Reverse Battery Protection

LT8672 是用于反向输入保护的有源整流器控制器。该器件驱动一个外部 N 沟道 MOSFET 以取代一个功率肖特基二极管。其非常低的静态电流和快速瞬态响应可满足存在高达 100kHz AC 输入信号之汽车应用中的严苛要求。对这些信号进行整流时在外部 FET 上产生的功耗极少,从而简化了 PCB 上的热管理。


工具及仿真模型

LTspice

LTspice® is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits.

To launch ready-to-run LTspice demonstration circuits for this part:

Step 1: Download and install LTspice on your computer.

Step 2: Click on the link in the section below to download a demonstration circuit.

Step 3: If LTspice does not automatically open after clicking the link below, you can instead run the simulation by right clicking on the link and selecting “Save Target As.” After saving the file to your computer, start LTspice and open the demonstration circuit by selecting ‘Open’ from the ‘File’ menu.
