S30454CH BTL Motor Drive IC
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.

Device Code
Year & Week 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
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.
