LA6583MC中文资料Single-Phase Full-Wave BTL Fan Motor Driver数据手册ONSEMI规格书

描述 Description

The LA6583MC is a low-saturation BTL output linear driving motor driver for single-phase bipolar fan motors. It features quite, low power, high efficiency drive that suppresses reactive current. It is optimal for use in applications that require miniaturization and low noise, such as CPU cooling fan motors and 5 to 12V electronic game products.

特性 Features

• Single-phase full-wave linear drive with BTL output (gain resistance 1K-360K)
• Low-voltage operation possible, with wide operable voltage range (2.8 to 13.8V)
• Low saturation output (Upper + lower saturation voltage: VO sat (total) = 1.1Vtyp, IO = 200mA)
• Lock protection and auto return circuits built-in
• Lock protection signal output (L during rotation, H at stop; open collector output)
• FG output (rotation speed detection output: open collector output)
• Hall bias built-in (VHB = 1.3V)
• Heat protection circuit (Design guarantee)
• Compact and high heat capacity package

应用 Application

• CPU cooling fan motors
• 5 to 12V electronic game products

简介

LA6583MC属于集成电路（IC）的全半桥驱动器。由制造生产的LA6583MC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。
