Features, Applications

The 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.

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.) Thermal shut-down circuit built in With thermal flag pin
