5-CHANNEL MOTOR DRIVER FOR DVD PLAYER
General Description
The AM5668 is a five-channel BTL driver IC, in
which four channels are voltage-type BTL drivers for
tracking and focus actuators, sled and spindle motors,
the other one channel is DC motor driver for tray
which supports forward/reverse control. This IC also
contains two general-purpose independent precise
voltage comparators.
The AM5668 is available in standard HSOP-28 pack-
age.

Note 2: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to
the device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Max-
imum Ratings" for extended periods may affect device reliability.
