Features
1) 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. 2) Wide dynamic range [9.0V (typ.) when Vcc1= Vcc2= 12V, at RL= 20Ω load]. 3) Separating power of Vcc1 and Vcc2 is to improve power efficiency by a low supply voltage for tracking, focus, and spindle. 4) Level shift circuit built-in. 5) Thermal shut down circuit built-in. 6) Mute mode built-in. 7) Dual actuator drivers: A general purpose input OP provides differential input for signal addition. The output structure is two power OPAMPS in bridge configuration. 8) Sled motor driver: A general purpose input OP provides differential input for signal addition. The output structure is one power OPAMP in bridge configuration. 9) Spindle driver: Single input linear BTL driver. The output structure are two power OPAMPS in bridge configuration. 10) Tray in-out driver: The DC motor driver supports forward/reverse control for tray motor. 11) 2 Built-in regulator controllers Adjustable range 1.5V ~ 4V |
Description
The AM5888S is a five-channel BTL driver IC for
driving the motors and actuators such as used in DVD player and consists
of two independent precision voltage regulators with adjustable range
from 1.5V to 4 V. It supports a variety of applications. Also, Pb free
package is selectable (Please refer to Marking Identification).
