AN8470NSA
Spindle motor driver IC for optical disk
s Overview
The AN8470NSA is a high performance IC
suited for driving a spindle motor of an optical disk
such as CD-ROM, PD, DVD, CD-R, CD-RW, etc.
s Features
• Low power consumption due to a direct PWM
system
• With start and stop pin
• Reverse breaking by EC/ECR voltage
• With Hall bias pin
• Surface-mount small package
s Applications
• High speed CD-ROM drive
PD, DVD, CD-R, CD-RW drives
