CSD96497集成电路（IC）的全半桥驱动器规格书PDF中文资料

CSD96497属于集成电路（IC）的全半桥驱动器。由德州仪器制造生产的CSD96497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。

3 Description

The CSD96497 NexFET™ power stage is a highly

optimized design for use in a high-power, highdensity

synchronous buck converter. This product

integrates the driver IC and power MOSFETs to

complete the power stage switching function. This

combination produces high-current, high-efficiency,

and high-speed switching capability in a small 5-mm

× 6-mm outline package. It also integrates accurate

current sensing and temperature sensing functionality

to simplify system design and improve accuracy. In

addition, the PCB footprint has been optimized to

help reduce design time and simplify the completion

of the overall system design.
