AN8783SB
4-channel linear driver IC for CD/CD-ROM drive
s Overview
The AN8783SB employs one channel of power
op-amp. system and three channels of H-bridge
system. Two channels out of three channels of H-
bridge method are a current feedback system. So
this IC is optimum for driving an actuator and a
motor of CD/CD-ROM drive. It comes with a
surface mount package which excels in a heat ra-
diation characteristic.
s Features
• Little phase delay due to current feedback system
(2-channel for actuator)
• 4 modes of forward, reverse rotations, braking and
standby can be selected from channels for load-
ing motor (H-bridge method) by a digital signal
from a microcomputer.
• Wide output dynamic range regardless of refer-
ence voltage of the system
• Setting the input level of a driver by an external
resistor is possible.
• PC (power cut) function built-in (common for ch.
1, ch. 3 and ch. 4)
• Thermal shut-down circuit built-in (with hyster-
esis)
s Applications
• CD/CD-ROM drive
