BA5983FM中文资料BTL Driver For CD-ROM数据手册ROHM规格书

描述 Description

Features : 
• Driver exclusively for the 4-ch BTL
• HSOP-M28 PIN power package
• A wide dynamic range [PreVcc=8V, PowVcc=5V, 4V(Typ.) when RL=8Ω]
• A built-in thermal shutdown circuit installed.
• The power supplies such as PreVcc, PowVcc of CH1 and CH2, and PowVcc of CH3 and CH4 are supplied independently to achieve an efficient drive.
• The standby mode can be controlled independently in CH1 to 3 and CH4.
• Setting all of CH1-4 to the standby mode leads the entire circuit to the standby mode.
• The driver pre-stage OP-amp features GND-sense and output rail-to-rail to make this IC suitable for a low voltage DSP.

简介

BA5983FM属于集成电路（IC）的全半桥驱动器。由制造生产的BA5983FM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。
