CSD95377Q4M集成电路（IC）的全半桥驱动器规格书PDF中文资料

CSD95377Q4M属于集成电路（IC）的全半桥驱动器。由德州仪器制造生产的CSD95377Q4M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 CSD95377Q4M NexFET™ power stage is a

highly-optimized design for use in a high power, high

density synchronous buck converter. This product

integrates the driver IC and power MOSFETs to

complete the power stage switching function. The

driver IC has built-in selectable diode emulation

function enables Discontinuous Conduction Mode

(DCM) operation to improve light load efficiency. This

combination produces high-current, high-efficiency,

and high-speed switching capability in a small 3.5

mm × 4.5 mm outline package. In addition, the PCB

footprint has been optimized to help reduce design

time and simplify the completion of the overall system

design.
