5-channel BTL Driver for DVD player

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 1.25V to 4 V. It supports a variety of applications. Also, Pb free package is selectable (Please refer to Marking Identification).

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 1.25V ~ 4V
  
Applications
   BTL driver for CD, CD-ROM and DVD.
