Part 1 - UIS/avalanche ratings The unclamped inductive switching (UIS) rating has proven to be a useful parameter since becoming prevalent in MOSFET data sheets in the mid-1980s. While repetitive avalanching of the FET is not recommended in actual applications, engineers have learned to use ...

This document just focuses on simple first order approximations that are compared to lab data. Because the MOSFET VDS slew occurs during the Miller region, the Miller charge (QGD) and gate drive strength can be used to approximate the slew rate. The first assumption that should be made is ...
For more details on common thermal impedance values in MOSFET data sheets, watch the video: Understanding MOSFET data sheets: Thermal Impedances. The overall goal of the thermal optimization of a package and printed circuit board (PCB) is to reduce the temperature rise in the presence of the ...

Gate drivers are used to drive the MOSFETs in our ESC. They’re connected to the gate of a MOSFET, hence the name “gate driver.” Older ESCs use simple transistors to drive the MOSFETs. Using dedicated gate drivers improves active braking effectiveness. Instead of having separate gate drivers...
符号的种类从小而简单的元器件(例如MOSFET)到在多个部件上创建的多引脚元器件(例如FPGA),不一而足。 与符号创建相关的注释: 放置在元器件库编辑器中的对象按照其放置顺序排列,使用Edit»Move命令来更改显示顺序。 引脚只有一端是带电的,该端被称为热点——确保热点远离元器件主体。欲了解更多信息,参阅引...
As an example, excerpts from TI motor driver data sheets are shown below. 3.1 Description The description summary on page one of the data sheet, as well as information on ti.com, usually lists the recommended maximum output current for the device: Features • Dual-H-Bridge Current-Control ...
Understanding Buck Power Stages in Switchmode Power Supplies 25 Component Selection The type of power switch considered in this report is a power MOSFET. Other power devices are available but in most instances, the MOSFET is the best choice in terms of cost and performance (when the drive ...
