BA6849中文资料3-phase motor driver for CD-ROMs数据手册ROHM规格书

描述 Description

3-phase motor driver for CD-ROMsThe 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.\u0001

特性 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.\u0001Applications
