VN5772AK-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 VN5772AK-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. The double high-side is made using STMicroelectronics®VIPower®M0-5 technology, while the low-side switches are fully protected VIPower M0-5 OMNIFET III. 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 integrate built-in non latching thermal shutdown with thermal hysteresis. An output current limiter protects the device in overload conditions. In the case of long overload duration, the device limits the dissipated power to a safe level-up to thermal shutdown intervention. An analog current sense pin delivers a current proportional to the load current (according to a known ratio) and indicates overtemperature shutdown of the relevant high-side switch through a voltage flag.The low-side switches have built-in non latching thermal shutdown with thermal hysteresis, linear current limitation and overvoltage clamping. In case of long overload duration, the low-side switches limit the dissipated power to a safe level up to the thermal shutdown intervention. Fault feedback for overtemperature shutdown of the low-side switch is indicated by the relevant status pin.

简介

VN5772AK-E属于集成电路（IC）的全半桥驱动器。由制造生产的VN5772AK-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。
