AN8787NSB
4-channel linear driver IC for CD/CD-ROM drive
s Overview
The AN8787NSB is a 4-channel driver IC that
has 2-channel of H-bridge method actuator driver
with current feedback, one channel of BTL type
traverse driver and one channel of tri-state output
type loading driver. It is optimum for actuator or
motor driver of CD/CD-ROM player. It comes with
a surface mount package that excels in heat radiat-
ing characteristic.
s Features
• Little phase delay due to current feedback method
(2-channel for actuator)
• Channels for loading motor (H-bridge system) are
available for three modes of forward rotation, re-
verse rotation and braking
• Muting SW with 2 modes: A loading channel is in
operation, and the other 3 channels are in muting;
Loading is in muting and the other 3 channels are
in operation.
• Standby switch to stop all functions
• Wide output dynamic range is available regard-
less of a reference power source on the system.
• I/O gain setting by an external resistor
• Thermal shut-down circuit built-in (with hyster-
esis)
s Applications
• CD/CD-ROM drive
• DVD/DVD-ROM drive
