ICs for Optical Disk Drive 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 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 combination with the AN8488SB, a spindle plus loading driver IC. A surface mount-type package of good heat radiation characteristic is used. 18.4±0.2 (5.15) (4.8) 28 22 21 15 (1.315) 8.3±0..

AN8737SB 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/IO = 800 mA)

* Standby function built in (all channels can be muted.)
