BTS7811K数据手册集成电路（IC）的全半桥驱动器规格书PDF

描述 Description

The BTS 7811K is part of the Trilith  IC™ family containing three dies in one package: One double high- side switch and two low- side switches. The drains of these three vertical DMOS chips are mounted on separated leadframes. The sources are connected to individual pins, so the BTS 7811K can be used in H- bridge- as well as in any other configuration. The double high- side is manufactured in SMART SIPMOS ® technology which combines low R DS ON vertical DMOS power stages with CMOS control circuit. The protected high- side switch contains the control and diagnosis circuit. To achieve low R DS ON and fast switching performance, the low- side switches are manufactured in S- FET 2 logic level technology.

简介

BTS7811K属于集成电路（IC）的全半桥驱动器。由制造生产的BTS7811K全半桥驱动器器件属于电桥驱动器电源管理集成电路 (PMIC) 系列，包含两个或多个功率晶体管，以及在外部器件控制下将其用作开关所需的电路。这些晶体管通常在内部配置为成对串联连接（称为半桥），因而任意指定晶体管对之间的结点都可以连接至两个电源轨中的任一个。这类器件常用于将控制器件（如微控制器）提供的低电平信号转换为操作执行器（如步进电机或无刷电机）所需的较大功率信号。
