NCP5338集成电路（IC）的全半桥驱动器规格书PDF中文资料

NCP5338属于集成电路（IC）的全半桥驱动器。由安森美半导体制造生产的NCP5338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。

The NCP5338 integrates a MOSFET driver, high−side MOSFET

and low−side MOSFET into a 6 mm x 6 mm 40−pin QFN package.

The driver and MOSFETs have been optimized for high−current

DC−DC buck power conversion applications. The NCP5338

integrated solution greatly reduces package parasitics and board space

compared to a discrete component solution.
