■ Overview

The AN8472SA is a high performance IC suited for driving a spindle motor of an optical disk such as CD-ROM, DVD etc. Small outline package can be used due to reduced power consumption by adopting the direct PWM drive system.

■ Features

• 3-phase full-wave 120° duty factor system

• Low power consumption due to a direct PWM system

• D-MOS transistor with low ON resistance (0.6 Ω typ.) on the output stage

• With start and stop pins

• Thermal shut-down function built-in

• With FG output pin

• Reverse breaking by EC/ECR voltage

• With Hall bias pin

• Surface-mount small package

■ Applications

• Optical disk drive of CD-ROM, DVD-ROM, CD-R, CD-RW etc.
