M56782FP
4 CHANNEL ACTUATOR DRIVER
DESCRIPTION
The M56782FP is a semiconductor integrated circuit in order to
drive 4ch actuator.
FEATURES
q Large power dissipation
q 3.3V DSP available.
q Low saturation voltage.
(Typical 1.35V at load current 0.5A and no bootstrap condition.)
q There are two motor power supplies.
Vm1 CH1, 2 motor power supply-1
Vm2 CH3, 4 motor power supply-2
q Flexible Input amp. setting. (It enables PWM control.)
q Low cross-over distortion.
q Wide supply voltage range. (4.5V – 13.2V)
q Built-in Thermal Shut Down circuit.
q Built-in Mute circuit.
APPLICATION
MD, CD-audio, CD-ROM, VCD, DVD etc.
