YD5954
ACTUATOR DRIVER WITH CURRENT FEEDBACK
FOR CD – ROM/DVD YD5954
DESCRIPTION
The YD5954 is a four-channel BTL driver IC for driving the motors and actuators in products such as
CD-ROM/DVD drivers. Two of the channels use current feedback to minimize the current phase shift caused by the
influence of load inductance.
FEATURES
*Wide dynamic range(4.0V(typ.) when Vcc=12V, PVCC=5V, and RL=8
*Level shift circuit on chip.
*Thermal shutdown circuit on chip.
