M56753FP
2-CHANNEL ACTUATOR MOTOR DRIVER
DESCRIPTION
The M56753FP is a semiconductor IC developed as the motor
driver used DVD, DVD-ROM, CD-ROM and CD Player.
This device include 2 channel BTL drivers and can drive 2actuators
with one IC at the same time.
Also, the mute circuit, thermal protection circuit and VREF voltage
monitor circuit functions are included.
FEATURES
●Low output saturation voltage (typ. 1.35V at 0.5A).
● Wide operating supply voltage range (4.5 to 15V).
● High current drive capability (maximum 0.9A).
● Low crossover distortion.
● High frequency capability.
APPLICATION
DVD, DVD-ROM CD-ROM, CD PLAYER
