CMOS BTL Drivers for DVD players
The ML58C88 is a five-channel CMOS BTL driver IC for driving the motors and
actuators in DVD players or other applications. The ML58C88 has independent
precision voltage regulators with adjustable range from 1.5V to 4 V.
APPLICATION
BTL. Driver for CD,CD-ROM and DVD.
FEATURES
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.
Wide dynamic range [4.5V
(typ.) when Vcc1 = Vcc2 = 5V,
at RL=20Ω load].
Separating power of Vcc1 and
Vcc2 is to improve power
efficiency by a low supply
voltage for tracking, focus and
spindle.
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 dirver. The
output structure are two power
OPAMPs in bridge configuration.
Tray in-out driver:
The DC motor driver
forward/reverse control
motor.

2 Built-in regulator controllers:
Adjustment range 1.5V ~ 4V
Level shift circuit built-in.
Thermal shut down circuit
built-in.
Dual actuator drivers:
A general purpose input OP
provides differential input
for signal addition. The
output structure is two
power OPAMPs in bridge
configuration.
