3-Phase spindle motor driver for CD-ROM

BD6662FS

Description

The BD6662FS is applicable for high speed slim

type CD-ROM due to the charging pump circuit.

This device is equipped with a current limiter,

FG output, reverse protection, rotational direction

detection, and is also power saving. With the use

of direct PWM drive method and MOS FET output,

BD6662FS is very functional and highly efficient.

Features

1) Built-in charging pump

2) Direct PWM drive

3) Low activating resistance

4) Low power consumption due to MOS FET output

5) Built-in reverse protection circuit

6) Built-in rotational direction detection terminal

7) Built-in current limiter circuit

8) Built-in thermal shut-down circuit

Applications

CD-ROM/RW, DVD-ROM
