BA6849集成电路（IC）的电机驱动器控制器规格书PDF中文资料

BA6849属于集成电路（IC）的电机驱动器控制器。由罗姆半导体集团制造生产的BA6849电机驱动器，控制器产品属于电机驱动器和控制器电源管理集成电路 (PMIC) 系列，可用于控制或操作从某电源施加到电机或相关机电执行器的电源。所实现的具体功能和特性集根据预期负载和预期应用的特性有很大差异，范围从用于有刷电机的简单开环速度控制到基于步进电机的高级闭环运动控制。

3-phase motor driver for CD-ROMs

The BA6849 series are ICs developed for CD-ROM spindle motor drives. These ICs possess a short brake and reverse rotation brake for two types of brake functions, and also contain FG output and rotation direction detection (FR) circuits, making them high-functionality and high-performance ICs.

Features

1) Three-phase, full-wave, pseudo-linear drive system.

2) Built-in power save and thermal shutdown functions.

3) Built-in current limiter and Hall bias circuits.

4) Built-in FG output.

5) Built-in rotation direction detector.

6) Built-in reverse rotation prevention circuit.

7) Built-in short brake pin.

Applications

CD-ROM, CD-R, CD-RW, DVD-ROM, and DVD-RAM
