om Motor Driver ICs
5A-Mch5.Da8an6ta8nShSeeletB4UT.cL Driver for DVD playerThe AM5868S is a five-channel BTL driver IC for driving the motors and actuators such as used in DVD player and
wwwconsists of two independent precision voltage comparators. It supports a variety of applications.
Applications
BTL driver for CD, CD-ROM and DVD.
omFeatures
.c1) Two comparators built-in:
Two general-purpose voltage open collector
Uoutput comparators are built-in.
t42) Two channels are voltage-type BTL drivers for
actuators of tracking and focus. Two channels are
evoltage-type BTL driver for sled and spindle
emotors. It is also built-in one channel bi-direction
hDC motor driver for tray.
3) Wide dynamic range [9.0V (typ.) when Vcc1=
SVcc2= 12V, at RL= 20Ω load].
ta4) Separating power of Vcc1 and Vcc2 is to
improve power efficiency by a low supply
avoltage for tracking, focus, and spindle.
.D5) Level shift circuit built-in.
6) Thermal shut down circuit built-in.
www7) Mute mode built-in.
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.
9) Sled motor driver:
A general purpose input OP provides differential
input for signal addition. The output structure is
one power OPAMP in bridge configuration.
10) Spindle driver:
Single input linear BTL driver. The output
structure are two power OPAMPS in bridge
configuration.
11) Tray in-out driver:
The DC motor driver supports forward/reverse
control for tray motor.
