AN8737SB
3-channel driver IC for optical disk drive
s Overview
The AN8737SB is a BTL type 3-channel driver
IC, adopting a current feedback system for 2 chan-
nels, which makes it optimum for an actuator and a
motor driver of CD-ROM/DVD-ROM. It can also
constitute an optimum system in combination with
the AN8488SB, a spindle plus loading driver IC. A
surface mount-type package of good heat radiation
characteristic is used.
s Features
• Little phase delay due to a current feedback system
(2 channels for actuator)
• The remaining channel is available for either
traverse or loading motor drive.
• Wide output dynamic range (4 V/I_O = 800 mA)
• Standby function built in (all channels can be
muted.)
• Thermal shut-down circuit built in
• With thermal flag pin
s Applications
• CD/CD-ROM player
• DVD/DVD-ROM drive
