MITSUBISHI <CONTROL / DRIVER IC>
M56783AFP
3 CHANNEL ACTUATOR DRIVER
DESCRIPTION
The M56783AFP is a semiconductor integrated circuit in order to
drive 3ch actuator.
FEATURES
●3.3V DSP available.
●Low saturation voltage.
●By taking advantage of the bootstrap function, the saturation
voltage can be lower.
●There are two motor power supplies.
Vm12 CH1, 2 motor power supply-1
Vm3 CH3 motor power supply-2
●7V power-supply is possible (Vm12 = 12V and MGND12 = 5V)
●Flexible Input amplifier setting. (It enables PWM control.)
●CH1 and CH2 can act in the Current Control mode.
●Low cross-over distortion.
●Wide supply voltage range. (4.5V – 13.2V)
●Including Thermal Shut Down circuit.
●Including 2 Operational Amplifiers.
●Including Mute circuit (2 lines).
APPLICATION
MD, CD-audio, CD-ROM, VCD, DVD etc.
