M56749FP - 4 CHANNEL ACTUATOR MOTOR DRIVER

General Description

The M56749FP is a semiconductor integrated circuit designed for a CD-ROM actuator driver.

This device can function 4 channel actuators by 1 chip due to include 4 channel BTL drivers.

Also, this device include a mute circuit, a Vcc check circuit and TSD function.
