BTS7751G集成电路（IC）的全半桥驱动器规格书PDF中文资料

BTS7751G属于集成电路（IC）的全半桥驱动器。由英飞凌科技股份公司制造生产的BTS7751G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。

描述 Description

The BTS 7751 G is part of the TrilithIC 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 lead frames. The sources are connected to individual pins, so the BTS 7751 G can be used in H-bridge- as well as in any other configuration. Both the double high-side and the two low-side switches of the BTS 7751 G are manufactured in SMART SIPMOS® technology which combines low RDS ON vertical DMOS power stages with CMOS control circuitry. The high-side switch is fully protected and contains the control and diagnosis circuitry. Also the low-side switches are fully protected, the equivalent standard product is the BSP 78.

In contrast to the BTS 7750 G, the BTS 7751 G offers an open load in Off-mode detection and slightly increased current limitation.
