AN8472SA
Spindle motor driver IC for optical disk
s 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 adopt-
ing the direct PWM drive system.

s 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
