AT5654
4-Channel BTL Motor Driver for CD-ROM
Features
˙AT5654 is a 4 channel driver for optical disc
motor driver. Dual channel current feedback
type drivers are built in, in addition to dual
channel motor driver.
˙Separating Vcc into Pre-power of sled motor,
Power of loading motor and Power of actuator,
can make batter power efficiency, by low
supply voltage drive.
˙Stand-by mode built in.
˙Thermal shutdown circuit on chip.
˙Compatible with BA5954
Description
The AT5654 is a 4-channel BTL driver IC for
driving the motors and actuators in products
such as CD-ROM/DVD-ROM/DVD-Player
drives. Two of the channels use current feedback
to minimize the current phase shift caused by the
influence of load inductance.
Applications
CD-ROM drives, DVD drives, DVD-ROM
drives.
