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
qLower saturation voltage.
(typical 1.35V at load current 500mA)
qWide supply voltage range.
(4.5V to 13.2V)
qLower cross-over distortion.
