APPLICATIONS
U 4 t .c om AM5868S Motor Driver ICs t a consists of two independent precision voltage comparators. It supports a variety of applications. w w w BTL driver for CD, CD-ROM and DVD. FEATURES
1) Two comparators built-in: Two general-purpose voltage open collector output comparators are built-in. 2) Two channels are voltage-type BTL drivers for actuators of tracking and focus. Two channels are voltage-type BTL driver for sled and spindle motors. It is also built-in one channel bi-direction DC motor driver for tray. 3) Wide dynamic range [9.0V (typ.) when Vcc1= Vcc2= 12V, at RL= 20Ω load]. 4) Separating power of Vcc1 and Vcc2 is to improve power efficiency by a low supply voltage for tracking, focus, and spindle. 5) Level shift circuit built-in. 6) Thermal shut down circuit built-in. 7) Mute mode built-in. w w w .D t a S a e h 8) Dual actuator drivers: A general purpose input OP provides differential input for signal addition. The output structure is two power OPAMPS in bridge configuration.
