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.

F

S

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.

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.

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

supports

forward/reverse

control

for

tray

motor.

2 Built-in regulator controllers:

Adjustment range 1.5V ~ 4V
