LA6585FA数据手册集成电路（IC）的全半桥驱动器规格书PDF

描述 Description

The LA6585FA is a single-phase bipolar fan motor driver that achieves quite operation, power savings, silent operation and high efficiency that suppresses reactive current through BTL output linear drive. It provides lock protection and rotation signal circuits on chip, and is optimal for applications that require high reliability and low noise, such as notebook personal computers, power supplies in consumer electronic equipment, car audio, and CPU cooling systems.

特性 Features

• BTL output single-phase full-wave linear drive (gain resistor : 1 to 360kΩ, 51dB)
• Supports low-voltage drive and features a wide usable voltage range (2.2 to 14.0V)
• Low saturation output (high side + low side saturation voltage : Vosat (total) = 1.2V (typical), IO = 250mA)
• Built-in lock protection and automatic return circuits
• Built-in FG output
• Built-in Hall sensor bias (VHB = 1.5V)
• Thermal protection circuit
• Small-sized, high thermal capacity package

应用 Application

• Consumer electronic equipment power supply
• Car audio system
• CPU cooling system
• White goods
• Car audio
• Notebook PC

简介

LA6585FA属于集成电路（IC）的全半桥驱动器。由制造生产的LA6585FA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。
