■ 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.
