YOUDA INTEGRATED CIRCUIT 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. ).
