Description

The S3045 is a four-channels BTL motor driver for driving the

actuators and motors for products of DVD-P/R/RW.

It embrace a two channels of current feed-back BTL drivers.

those use current feed-back process to minimize the current phase

shift from the load inductance of actuators

It supports various applications with pb free and heat-sink package.

Application

◈CD-ROM

◈CD-RW

SSOPH-28N

With Heat-sink

◈DVD-PLAYER

◈DVD-ROM

◈DVD-RW

① Device Code

◈Dual Actuator drivers [ Current Feedback ]

The current feedback technique can reduce the current

phase shift caused By the load inductance of actuators

◈Sled motor driver

② Year & Week Code

A general OP-AMP connected to the input terminal helps

compute additions of differential inputs or signals.

◈Loading motor driver

Single input linear BTL driver. The output structure are two

power OP-AMPS in bridge configuration.
