5-CHANNEL MOTOR DRIVER FOR DVD PLAYER
General Description
The AM5669 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 independent precise voltage regulators
with adjustable range from 1.5V to 4V and a free com-
parator for spindle channel motor direction detection.
The AM5669 is available in standard HSOP-28 pack-
age.
