SC32300B数据手册集成电路（IC）的全半桥驱动器规格书PDF

描述 Description

The SC32300B is a high-side and low-side N-channel MOSFET driver with integrated bootstrap switch. This driver can be used as a synchronous buck converter MOSFET driver. It can also be used together with the SC32300A in applications driving a DC motor or similar load. An external capacitor to program the dead-time offers the flexibility to design the switch clamp circuitry and produce more reliable system operation for the DC motor driving application. The SmartDrive™ function at the turn-on of the high-side MOSFET is a standout feature of this part to reduce the EMI. The diode emulation mode operation offers the opportunity to achieve high efficiency at light load. The integrated LDO reduces the cost and the footprint of the system.

简介

SC32300B属于集成电路（IC）的全半桥驱动器。由制造生产的SC32300B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。
