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 channels, which makes it optimum for an actuator and a motor driver of CD-ROM/DVD-ROM. It can also constitute an optimum system in bination with the AN8488SB, a spindle plus loading driver IC. A surface mount-type package of good heat radiation characteristic is used.
