Features and Benefits
◈ 1 Channel is bi-directional DC motor driver for tray.
◈ 4 Channels are voltage-type BTL drivers for
actuators[ focus, tracking ] and sled, spindle motors.
◈ Separating power of Vcc1 and Vcc2 is to improve power efficiency.
◈ Built in Level shift circuit.
◈ Built in Thermal shut down circuit.
◈ Built in Mute mode.
◈ Dual Actuator drivers
A general purpose input OP Provides differential input for signal addition.
The output structure is two power OPAMPS in bridge configuration.
◈ Sled motor driver
A general purpose input OP provides differential input for signal addition.
The output structure is one power OPAMP in bridge configuration.
◈ Spindle driver
Single input linear BTL driver. The output structure are two power
OPAMPS in bridge configuration.
◈ Tray Bi-directional driver
The DC motor driver supports forward/reverse control for tray motor.
