LA6585MC中文资料Single-phase Full-wave BTL Fan Motor Driver数据手册ONSEMI规格书

描述 Description

The LA6585MC is single-phase bipolar fan motor is driven, through BTL output linear drive, at high efficiency, low power, and low sound by suppressing the reactive power. Lock protection, rotary signal circuits are incorporated, which is optimum for the notebook PC, consumer equipment power supply, car audio system, CPU cooler, etc. that require high reliability and low noise.

特性 Features

• Pre-driver for single-phase full-wave drive
• Single-phase full-wave linear drive by BTL output (gain resistance 1kΩ-360kΩ, 51dB)
• Low-voltage operation possible, with wide operating voltage range (2.2 to 14.0V)
• Low saturation output (Upper + lower saturation voltage : VOsat (total) = 1.2Vtyp, IO = 250mA)
• Built-in lock protection and automatic reset circuits
• Built-in FG & RD outputs
• Built-in Hall bias (VHB = 1.5V)
• Thermal protection circuit
• Extra-small & high heat capacity package

应用 Application

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

简介

LA6585MC属于集成电路（IC）的全半桥驱动器。由制造生产的LA6585MC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。
