VN770KP-E数据手册集成电路（IC）的全半桥驱动器规格书PDF

描述 Description

The VN770KP-E is a device formed by three monolithic chips housed in a standard SO-28 package: a double high side and two low side switches. Both the double high side and low side switches are made using STMicroelectronics VIPower™ M0-3 Technology.
This device is suitable to drive a DC motor in a bridge configuration as well as to be used as a quad switch for any low voltage application.
The dual high side switches have built-in thermal shutdown to protect the chips from over temperature and current limiter blocks to protect the device from short circuit. Status output is provided to indicate open load in off and on-state and over temperature.
The low side switches are two OMNIFET II types (fully auto protected Power MOSFET in VIPower™ technology). They have built-in thermal shutdown, linear current limitation and overvoltage clamping. Fault feedback for thermal intervention can be detected by monitoring the voltage at the input pin.

简介

VN770KP-E属于集成电路（IC）的全半桥驱动器。由制造生产的VN770KP-E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。
