AM5888S
Motor Driver ICs
5-channel BTL Driver for DVD player
AM5888S
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.
Applications
BTL driver for CD, CD-ROM and DVD.
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= 20 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
