M56749FP

4 CHANNEL ACTUATOR MOTOR DRIVER

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.

FEATURES

●Lower saturation voltage.
(typical 1.35V at load current 500mA)

●Wide supply voltage range.
(4.5V to 13.2V)

●Lower cross-over distortion.
