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